Protecting the Health of U.S. Military Forces in Romania: Endemic Disease Threat Considerations

INTRODUCTION

Romania is located in southeastern Europe, on the lower Danube, bordering on the Black Sea. Romania shares borders with Hungary and Serbia to the west, Ukraine and Moldova to the northeast, and Bulgaria to the south. Romania has an area of 91,699 square miles, with 90 miles of Black Sea coastline, which provide an important outlet to the Mediterranean Sea and the Atlantic Ocean. Almost all of the Danube Delta is located within Romanian territory.

Romania has 22.3 million inhabitants with about 55% living in urban areas. The capital Bucharest is also the country's most populous city, home to 1 .9 million people according to a 2002 national census.

In 2002, the World Health Organization (WHO) estimated the life expectancy in Romania to be 71.4 years on average (75 years for females and 67 years for males).1 Communicable diseases accounted for about 1% of deaths. Infectious/parasitic diseases and respiratory diseases ranked 8th and 10th, respectively, in the top 10 conditions tìiat account for about 90% of the burden of diseases in Romania (3.2% and 3.1% total disability-adjusted life years Disability-adjusted life years (DALY) is a measure for the overall "burden of disease." Originally developed by the World Health Organization, it is becoming increasingly common in the field of public health and health impact assessment (HIA).  [DALYs], respectively). Respiratory diseases accounted for 6% of all deaths in 2003, with pneumonia causing higher mortality rates than chronic lower respiratory diseases. By contrast, cardiovascular and neuropsychiatrie conditions accounted for the highest burden of disease (42% total DALYs) among the Romanian population regardless of sex.1 Sexually transmitted diseases Sexually transmitted diseases

 cases). Since 1994-1995, there has been a steady increase in the HIV/AIDS HIV/AIDS Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome  incidence rate among adults, mainly related to transmission of the virus via sexual contact and injected drug use. The increase in sexual transmission is correlated with a growing incidence in other STDs, particularly syphilis.1

The country is divided into 41 counties or districts (see Figure 1), with one municipality each where the seat of county administration is located. A network of 5,500 dispensaries constitutes the primary health care system, while polyclinics and hospital emergency rooms deliver ambulatory secondary heahh care.2 Tertiary care is delivered through a network of civilian and military hospitals, with a range of subspecialty subspecialty,

The 1 1 military hospitals also provide civilian care, and are located in the following cities: Sibiu, Piteçti, Timi§oara, Oradea, Braçov, Cluj-Napoca, Craiova, Focsani, Constanza, and Bucharest. Most of the health care system is owned by the state, though private practice has been allowed since 1990. The quality of health care available varies greatly, but overall, it is well below U.S. standards.

The term "lily pads" was coined in 2003 by General James Jones, the former Supreme Allied Commander Supreme Allied Commander is the title given to the most senior commander of some multinational military alliances. It originated as a term used by the Western Allies during World War II and is currently used by NATO.  in Europe, to describe the concept of 'jumping-off points. Others have referred to them as frontier posts along the U.S. security perimeter. Whatever the name, the new installations constitute a strategic shift (part of the Military Global Posture Review) intended to place U.S. forces closer to potential areas of conflict in North Africa, the Middle East, and Central Asia.

All U.S. Army and Air Force training operations in Romania will fall under the command of JTF-East. From the headquarters at the MK Air Base between 100 and 300 personnel will oversee rotations of brigade-sized Army units, and Air Force weapons training deployments, at Cincu, Smârdan, and Babadag Training Ranges. JTF-East will also oversee training in neighboring Bulgaria, at Bezmer Air Base The Bezmer Air Base is situated in the eastern part of the Upper Thracian Lowland, in Yambol Oblast (Region), 10 km west of the city of Yambol and 30 km southeast of the city of Sliven, between the villages of Bezmer and Bolyarsko, and near the Sofia-Burgas railway.  and the Novo Selo Army Training Range near the border with Turkey, and Graf Ignatievo Airfield in central Bulgaria, according to the U.S.-Bulgaria agreement signed in 2006.

Cincu Training Range is located on the territory of two counties, Sibiu and Brasov (15 miles east of me city of FagarasJ. The range has approximately 40 square miles of land and 62 miles of maintained access roads, but no fixed billeting facilities.

Smârdan (Malina) Training Range is located in the county of Galati, a port on the Danube River. Established in 1951, it occupies nearly 33 square miles of land, and has billeting facilities for 600 troops.

Babadag Training Range is located in the county of Tulcea, 12 miles southeast of Babadag city. It occupies 10 square miles of land and has fixed billeting facilities for 230 troops. The range is in the immediate vicinity of the Danube Delta, the largest and best preserved of Europe's deltas, home to 12,00016,000 people and over 2 million birds. MK Air Base is located in me county of Constanta. It has an 1 1,480-foot concrete runway and facilities for flight management, administration, and personnel billeting, as well as warehouses and hangars.3

The counties of Constanta and Tulcea comprise the Romanian (northern) portion of the Dobrogea region, located between the lower Danube Delta and the Black Sea. To the west of this region there are the counties of Galati (where the Smârdan Training Range is located), Braila, Calarasi, and Ialomija (see Figure 1). Southern Dobrogea region belongs to Bulgaria (and includes Dobrich and Silistra territorial areas). For the purpose of this article, discussions refer to the Romanian portion of the Dobrogea region and includes the nearby county of Galati (where the Smârdan Training Range is located).

There are several sources of information with regard to Romania and related Force Healtii Protection measures (summarized in Table I), which include infectious disease threat awareness and immunization immunization: see immunity; vaccination.  requirements. However, it is this author's opinion that a proactive clinical and environmental surveillance in the Dobrogea region and an integration of open source information will substantially help in informing the commanders' decision on implementing a successful Force Health Protection program regardless of the duration of deployment for training.

Anthrax

Natural outbreaks of anthrax occur periodically in Romania especially in the Dobrogea region. Human cases are usually linked to the consumption of contaminated meat, although herding infected animals and handling carcasses are also risk factors. Vector transmission of the causative agent Bacillus anthracis is rare; however, cutaneous anthrax, the result of transmission by horseflies, has been historically described.4

The chronology of anthrax outbreaks in Romania, reported in recent years by local health authorities and the media is as follows:

* August 2000, 38 human cases and 2 deaths; 17 were lab confirmed; disease was detected in sick cattle, horses, pigs and sheep.

* July 2005, 42 people consumed anthrax-infected beef and goat meat.

* September 2005, 1 person dead (bacteria detected in the cerebrospinal fluid (CSF Cerebrospinal Fluid (CSF) Analysis Definition

 cases.

The extent of anthrax disease may be underestimated because of underreporting and self-treatment (antibiotics are purchased over the counter). Although Romania has an ongoing livestock vaccination program, the occurrence of natural outbreaks suggests both noncompliance noncompliance

failure of the owner to follow instructions, particularly in administering medication as prescribed; a cause of a less than expected response to treatment.

noncompliance 
 with the program and a significant reservoir of spores in the soil. Anthrax spores are very hardy and may persist in soil for decades. Ploughing soil containing B. anthracis spores can infect large numbers of livestock. Louis Pasteur reported that spores can pass through the digestive tract of earthworms.5 This would help spread the disease through the soil if the carcasses were simply buried or left for long times in the field. Although the disease does not readily pass directly between animals, this dispersal mechanism can contaminate large areas of land fairly rapidly. Of note, wouldbe terrorist Larry Wayne Harris reportedly obtained anthrax bacteria by exhuming cattle that had died of anthrax.5

The airborne anthrax infectious dose is not well defined and it may vary widely, from a few hundred spores to a few thousands depending on the agent virulence, environmental and host factors.6,7 B. anthracis can be readily grown on blood agar plates from contaminated soils but scientific data to support human infection from spores present in the soil are not available. In the absence of such data and of studies assessing the anthrax spore load of soil in the Dobrogea region or the risk of acquiring infection during military training operations such as live fire exercises at the Babadag training area (especially during the dry summer months) when the soldiers are more at risk for being exposed to contaminated dust, it is difficult to foresee whether the implementation of an anthrax vaccination program (for troops deploying to Romania for training and not previously vaccinated) would provide an added value to the Force Health Protection. However, an increased awareness of potential pulmonary disease occurrence as a result of inhalation of anthrax spores present naturally in the environment should be underscored.

Brucellosis

Most cases can be traced directly to infected livestock. Infection with Brucella Brucella /Bru·cel·la/ (broo-sel´ah) a genus of schizomycetes (family Brucellaceae). B. abor´tus causes infectious abortion in cattle and is the most common cause of brucellosis in humans. B.  spp. can come from handling contaminated meat or hides or from drinking milk from infected herds. The bacteria can survive for several weeks in milk, water, urine, or damp soil. However, it will die relatively quickly in dry conditions and is killed by sunlight.

Human cases of brucellosis in Romania are rare, but outbreaks in livestock do occur. In 2000 there were 47 cases in swine and 270 cases in sheep.8 Brucellosis (caused by B. melitensis) has been a notifiable disease since 19% and no cases have been officially confirmed since then. However, data on human zoonotic Zoonotic

 cases are sparse in Romania and were not provided to the European Commission in 2000.9 In March 2007, a case of human brucellosis was reported in the local media but it was believed to have been contracted in Spain.7 Brucellosis outbreaks may occur after a significant time as is the case with Bulgaria, which did not have B. melitensis cases since 1941 but recently (June 12, 2006) reported to the World Organization for Animal Healtii several cases of infection. Four goats were diagnosed with B. melitensis infection, all of which were destroyed. In August 2007, in the Bulgarian village of Vuce, three human cases of brucellosis were reported and four others were suspected.

Brucellosis may present itself as an acute, febrile febrile /feb·rile/ (feb´ril) pertaining to or characterized by fever.

Q Fever

Q fever (also known as the Balkan flu) is a rickettsial disease caused by Coxiella burnetii. Tick species may transmit bacteria by infecting livestock and pets. Extremely virulent, one bacterium can cause infection. Moreover, Coxiella are also very hardy for nonsporulating organisms and can survive for months in dust and feces particles not affected by hot dry conditions. In 2004, in Avrig, Romania, an outbreak of Q fever was reported by local health authorities and the media.10 Fourteen cases of atypical pneumonia hospitalized between March and April 2004 were confirmed serologically to be the result of Q fever. The disease was linked to the consumption of unpasteurized dairy products and/or contact with feces of infected animals.

However, Q fever should be considered in differential diagnosis when there is a history of animal contact.

Rabies

It is a zoonotic disease caused by a rhabdovirus rhabdovirus

Any of a group of viruses responsible for rabies and vesicular stomatitis (an acute disease of cattle and horses, characterized by blisters in and about the mouth, that resembles foot-and-mouth disease).
 of the genus Lyssavirus, affecting a wide range of domestic and wild animals, including bats. However, in Europe, bat rabies is an epidemiologically distinct disease from classical rabies found in terrestrial animals. Animal bites are the most efficient means of transferring the virus but rarely infection can be caused by scratches that are contaminated with saliva.

Although a 2007-2016 Rabies Eradication Program based on vaccination of wild and domestic animals is ongoing in Romania, sporadic cases of human rabies are still reported. In 1986-2001 there were 42 human cases including one fatality, most of them involving contact with wild rabid animals. Quarantine was recently instituted in 4 counties because of rabies in a cow bitten by a rabid fox and all people who had contact with the animal have been vaccinated. 12 From January 1 to March 31, 2007, 71 cases of rabies were reported to the WHO, a reduction from the 106 cases reported for the first quarter of 2006 (54 in wildlife, 16 in domestic animals, 0 in bats, and 1 in humans).13 The human case reported in Romania (admitted on March 16, 2007; deceased on March 27, 2007) was diagnosed as rabies only at the necropsy necropsy /nec·rop·sy/ (nek´rop-se) examination of a body after death; autopsy.

; the body did not show any signs of animal bites. In 2004, in the county of Brasov, a rabid brown bear killed two people and injured several others; all the injured received appropriate postexposure prophylaxis.14 From 2002 to 2005, the number of domestic animals (mostly dogs and cats) diagnosed with rabies increased.14 Urban rabies, because of feral or stray dogs roaming city streets, often in packs, is of concern since dog attacks are not uncommon (i.e., a 68-year-old Japanese businessman was killed in 2006 downtown Bucharest after a stray dog bit him in the leg severing an artery). In Galati city the number of stray dogs increased from a few hundred in 1989 to about 10,000 in 2004.15 The large number of stray dogs may also pose a risk for echinococcosis/hydatidosis as human cases are sporadically reported.

Rabies virus infects the central nervous system, causing swelling of the brain (encephalopathy) and eventually death within days of the onset of symptoms, if not treated.11 The U.S. Embassy in Romania recommends rabies pre-exposure immunization for everyone over the age of 2 for embassy personnel before arriving in the country.16 There are currently two rabies vaccines licensed in the United States. The current Department of Defense (DOD (1) (Dial On Demand) A feature that allows a device to automatically dial a telephone number. For example, an ISDN router with dial on demand will automatically dial up the ISP when it senses IP traffic destined for the Internet. ) policy is to administer rabies vaccine to personnel with a high risk of exposure (e.g., animal handlers; certain laboratory, field, and security personnel; personnel frequently exposed to potentially rabid animals in a nonoccupational or recreational setting).17 Postexposure prophylaxis with rabies immunoglobulin is also available. Most importantly, the risky behavior of petting or feeding stray dogs should be avoided as the perception of rabid dogs as aggressive and foaming at the mouth is misconstrued (these symptoms begin only after the brain is infected).

Cholera

Cholera is caused by Vibrio cholerae, which leads to severe diarrhea, a massive loss of fluid from the body that can cause death in a few hours. Sporadic cases were reported, especially in or nearby Danube Delta counties. Infections associated with the consumption of raw seafood have been reported along the Black Sea coast. Although 300 cases have been reported to WHO between 1990 and 1995 (with 66 cases in August 1990 in Tulcea County), the epidemiology of cholera in Romania is unknown and data are further complicated by over-the-counter sales of antibiotics and self-medication.

The rule of thumb for protection against food- or waterborne diseases, as recommended by USACHPPM USACHPPM United States Army Center for Health Promotion and Preventive Medicine , is to assume that all food, ice, and water not approved by the U.S. military are contaminated. Oral rehydration rehydration /re·hy·dra·tion/ (-hi-dra´shun) the restoration of water or fluid content to a patient or to a substance that has become dehydrated.

HFRS

HFRS is an elevated disease threat in the Balkans. It is caused by hantavirus infection, which can result from the inhalation of aerosolized Adj. 1. aerosolized - in the form of ultramicroscopic solid or liquid particles dispersed or suspended in air or gas

In general, case-fatality rates range from less than 0.1% for HFRS caused by Puumala virus to 5-10% for HFRS caused by the Hantaan virus. Supportive care is indicated in hantavirus infection, as there is no specific treatment or licensed vaccine available.

Tick-Borne Diseases

Tick-borne diseases should be considered a serious threat to personnel deployed to the region because of the high level of exposure to tick vectors. Medical threat awareness, use of DOD insect repellent system and proper wear of permethrintreated uniforms will help minimize the risk of acquiring a tick-borne disease especially during the spring and summer when the ticks are most active. No tick-borne encephalitis encephalitis (ĕnsĕf'əlī`təs), general term used to describe a diffuse inflammation of the brain and spinal cord, usually of viral origin, often transmitted by mosquitoes, in contrast to a bacterial infection of the meninges  (TBE) vaccines are available or licensed in the United States.

Crimean-Congo hemorrhagic fever Crimean-Congo hemorrhagic fever

a zoonotic disease of humans, in central Asia through to eastern Europe, who are in contact with livestock. Caused by a bunyavirus, it is transmitted by ticks. The principal signs are fever, widespread hemorrhages and necrotizing hepatitis.
 (CCHF CCHF Crimean-Congo Hemorrhagic Fever
CCHF Congo Cerebral Hemorrhage Fever
) is a viral encephalitis transmitted by Hyalomma marginatum ticks, which are most active April-August, reaching peak feeding activity April-May. Health care workers may be at risk for acquiring infection via contact with contaminated body fluids if proper infection control measures are not used. Treatment of CCHF is primarily supportive but ribavirin ribavirin /ri·ba·vi·rin/ (ri?bah-vi´rin) a broad-spectrum antiviral used in the treatment of severe viral pneumonia caused by respiratory syncytial virus, particularly in high-risk infants; also used in conjunction with interferon  has also been used with some benefit.11 European TBE is transmitted by Ixodes ricinus (the same tick transmits Lyme disease) and is widely distributed in brushy and forested areas at elevations up to 1,500 m. TBE is endemic in Europe except in the Benelux countries and the Iberian Peninsula. In Romania there is higher risk of TBE in Tulcea County and in Transylvania. The exact number of humans affected by TBE in Romania is not known and epidemiological studies of prevalence are not available. The only treatment currently available is supportive.

Boutonneuse fever (also known as Mediterranean spotted fever) is also endemic along the Black Sea coast and in the city of Bucharest and is transmitted by the dog tick Riphicephalus sanguineus. From January until June 2007 there were 13 cases of boutonneuse fever reported at the Infectious Diseases Hospital in Constanta.20 Symptoms include fever, myalgia myalgia /my·al·gia/ (mi-al´jah) muscular pain.myal´gic

The risk of acquiring boutonneuse fever upon contact with dogs should be emphasized to troops deployed in the area.

Mosquito-Borne Diseases

West Nile Virus West Nile virus, microorganism and the infection resulting from it, which typically produces no symptoms or a flulike condition. The virus is a flavivirus and is related to a number of viruses that cause encephalitis.  

West Nile virus (WNV WNV West Nile Virus

). However, infection will complicate diagnoses since fever cannot be clinically distinguished from other arboviral fevers. WNV has an infection cycle that involves birds and mosquitoes feeding on both birds and humans (primarily members of the Culex Culex /Cu·lex/ (ku´leks) a genus of mosquitoes found throughout the world, many species of which are vectors of disease-producing organisms.

Tahyna Virus

Tahyna virus, which causes influenza-like fever and respiratory symptoms and sometimes central nervous system involvement, is widespread across Europe and the virus was isolated and detected serologically in Romania.24 Birds and rabbits are vertebrate hosts. Since the Danube Delta is a major migratory route for birds, Tahyna virus has the potential to emerge as a significant human pathogen in the area. Other two Bunyaviruses, Batai and Lednice viruses, have also been reported in Romania.24

For Force Health Protection guidance on mosquito-borne diseases see references provided in Table I. There is no specific treatment for the West Nile or Tahyna virus infections; in severe cases, supportive therapy is indicated.

Tuberculosis (TB)

TB is a major health problem in Romania. In 2004, 31,567 cases ofTB were reported to WHO (134.6 cases per 100,000), and a total of 2,387 TB deaths were reported in 2003 (the second highest notification rates in the WHO European Region), 10 times higher than the average rate in the European Union (EU).25 Eastern Europe also has the highest levels of multi-drug resistant TB (MDR-TB MDR-TB Multi-Drug Resistant Tuberculosis ) in the world and TB here is 10 times more likely to be MDR-TB than in the rest of the world.25

The first outbreak of H5N1 highly pathogenic avian influenza (HPAI HPAI Highly Pathogenic Avian Influenza

) in domestic poultry was registered in October 2005 in Tulcea County (less than 20 miles from the Babadag training area). By May 31, 2006, the total number of reported avian flu outbreaks in Romania had reached 116 (in the Danube Delta, Transylvania, and Bucharest). Romanian authorities have taken measures to contain the outbreaks including culling of tens of thousands of birds, banning the sale of live birds and pigs in markets, confining domestic birds and pigs indoors or in closed yards countrywide, giving annual influenza vaccine to residents and military operating in the area, disinfection disinfection,

 of vehicles, and restricting access to affected areas.

Romanian military were actively involved in quarantine and infection control measures.27 Seventeen patients with suspected H5N1 infection were tested at the National Influenza Centre in Bucharest, and all tested negative. A second outbreak in backyard poultry was reported in November 2007 in Murighiol village, Tulcea County.

Although there is currently no vaccination for the H5N1 virus that causes avian influenza, maintaining good basic hygiene practices and avoiding contact with wild birds or poultry remain the best defense at this time when the virus is not yet adapted for human infection and transmission.

Since the avian outbreaks first occurred in the Danube Delta region, it is likely that the H5N1 HPAI was introduced in the country by migratory waterfowl waterfowl, common term for members of the order Anseriformes, wild, aquatic, typically freshwater birds including ducks, geese, and screamers. In Great Britain the term is also used to designate species kept for ornamental purposes on private lakes or ponds, while in  and transmitted via contact of wild migratory or shorebirds with poultry as well as human factors.

The U.S. government is actively involved in providing technical and financial assistance to Romania for avian influenza surveillance, epidemiology, rapid diagnostics, and disease containment training.28

DISCUSSION

The NCMI (formerly Armed Forces Medical Intelligence Center The Armed Forces Medical Intelligence Center (AFMIC), based in Fort Detrick, Maryland, is an agency within the United States Department of Defense (DoD) within the Defense Intelligence Agency (DIA); its mission is to track and assess the full range of global health issues for the  [AFMIC AFMIC Armed Forces Medical Intelligence Center

]) assessment of Romania indicates an intermediate risk for infectious diseases, with food and water-borne diseases posing the main operation threat (11-50% attack rate per month).

Although this risk assessment applies to the country overall, unique regional factors should be considered when implementing an effective FHP program for U.S. military forces deploying at the Romanian training bases. The JTF-East headquarters and 3 out of 4 training bases (Babadag, MK, and Smârdan) are located in the Dobrogea region, in the immediate vicinity of Danube Delta where over 2 million birds and up to 16,000 people live. Outbreaks in this population of fishermen, cattle and bee breeders occur frequently, and have historically included WNV, anthrax, diphtheria, cholera, and suspected HPAI. Population-specific data in the region are not available, and disease cases may be underreported because of over-the-counter sale of antibiotics.

Deployments to Eastern Europe thus pose unique challenges but also opportunities for implementing robust infectious disease surveillance and control measures. In addition to a proactive clinical and environmental surveUlance, a joint U.S.-Romanian implementation of surveillance and testing of mosquitoes, ticks, and sand flies for various arthropod-borne diseases, characterization of pathogens, and their use in serological serological

Although the surveillance of environmental quality of the air, soil, and potable water supplies at FOBs is a matter of standard policy, the U.S. bases in Romania may require a biological site assessment to include soil sampling and testing for the presence of Coxiella burnetti, Brucella spp, and B. anthracis bacteria and spores, to evaluate the risk of potential exposures to biological hazards. The occurrence of anthrax outbreaks suggests both noncompliance with the government sponsored livestock vaccination program and the presence of a large reservoir of spores in the environment.

 procedures were historically applied elsewhere (for instance in former BW testing sites such as the Rebirth Island in the Aral Sea and the Gruinard Island near Scotland) and were deemed not to cause soil infertility while killing the anthrax spores (among others, the British used a solution of formaldehyde 5% in seawater applied at a rate of 50 liters per square meter).29 U.S. Army personnel with expertise in environmental testing and remediation may originate from the following organizations:

- U.S. Army Center for Health Promotion and Preventive Medicine (USACHPPM) provides worldwide technical support for implementing preventive medicine, public health, and health promotion/wellness programs.

- U.S. Army's first and ninth area medical laboratories (AMLs) provide health hazard surveillance to Army, joint, or combined forces through robust analytical capabilities.

- The 20th Support Command Chemical, Biological, Radiological, Nuclear, and High- Yield Explosive (CBRNE CBRNE Chemical Biological Radiological Nuclear Explosive

A robust preventive medicine (PVNTMED PVNTMED Preventive Medicine ) in the context of a sustained FHP program should be an integral part of JTF-East Force Health Protection operations regardless of the length of deployment for training of U.S. troops in Romania, and effective tools should be implemented to standardize and enhance human and animal infectious disease surveillance in the area. Because of the presence of endemic biological agents of BT/BW concern in Romania, a robust laboratory capability is essential in early recognition of a natural outbreak versus a bioterrorism attack. A delay in the identification of causative agents of disease may delay the time to treatment. In addition, although the municipal hospital in Constanta may provide urgent medical care for troops, the availability of advanced laboratory testing or specific medical countermeasures such as the botulinum antitoxin antitoxin, any of a group of antibodies formed in the body as a response to the introduction of poisonous products, or toxins. By introducing small amounts of a specific toxin into the healthy body, it is possible to stimulate the production of antitoxin so that the  may be optimally provided by U.S. Army Medical Department personnel on site considering the overall status of health care facilities in Romania.

Another area of consideration and improvement would be the medical intelligence collection. Currently, data on clinical and basic research on military significant pathogens in a country of interest can only be obtained from disparate sources since the NCMI does not provide such information on these topics. Such a pathogen-specific database may arm U.S. personnel with scientific and epidemiological data to implement an effective PVNTMED/FHP program and focus future studies on emerging pathogens.

Monitoring of local media by deployed U.S. personnel as demonstrated during the ROMEX'05 U.S.-Romanian exercise may provide advance knowledge of current or emerging medical or environmental threats in the area to the JTF-East commander, so that preemptive or mitigation measures can be planned for and rapidly implemented.

Although usually used to address the need for increased awareness to the social, ethnographic, cultural, economic, and political elements of the people among whom a force is operating, the principles of the "human terrain system The Human Terrain System is a program under the auspices of the US Military in Iraq and Afghanistan. It utilizes experts in anthropology, language and intelligence to understand how societies make decisions and how attitudes are formed in order to assist the US Military in "30 may potentially be applied in the medical context to give commanders an organic capability to understand and mitigate at the operational and tactical levels the regional medical threats and thus the "medical human terrain." A putative "medical human terrain team" in the JTF-East could function as an FHP advisor to the brigade-size units rotating for training in the area ensuring all activities account for the human terrain/medical threat dimension of the AOR, providing three primary capabilities: (a) expert medical advice based on a constantly updated, userfriendly medical threat database on the AOR; (b) the ability to direct focused study on medical issues of specific concern to the commander; and (c) a reach-back link to a network of subject matter experts in the United States. No such system currently exists for understanding the human "medical threatcentric" terrain and integrating this "medical human terrain layer" into the common operational picture to achieve medical, situational, and regional awareness.

Last but not least, organizing a multinational conference focused on military PVNTMED and FHP issues in the JTF-East AOR would lead to an increased understanding of host nations' capabilities and an invaluable exchange of PVNTMED information in a combined force environment.
