Health impacts. (Technical Briefs).Potential infectious risks include the spread of sometimes resistant microorganisms from health care establishments into the environment. These risks have so far been poorly investigated. Wastes and by-products also can cause injuries. Sharps Throughout the world, an estimated 12 billion injections are administered every year. Not all needles and syringes are properly disposed of, so sharps pose a considerable risk for injury and infection, through accident as well as reuse. * The reuse of syringe needles without sterilization is estimated to cause eight to 16 million hepatitis B Hepatitis B Definition Hepatitis B is a potentially serious form of liver inflammation due to infection by the hepatitis B virus (HBV). It occurs in both rapidly developing (acute) and long-lasting (chronic) forms, and is one of the most common chronic infections each year, 2.3 to 4.7 million hepatitis C Hepatitis C Definition Hepatitis C is a form of liver inflammation that causes primarily a long-lasting (chronic) disease. Acute (newly developed) hepatitis C is rarely observed as the early disease is generally quite mild. infections, and 80,000 to 160,000 HIV HIV (Human Immunodeficiency Virus), either of two closely related retroviruses that invade T-helper lymphocytes and are responsible for AIDS. There are two types of HIV: HIV-1 and HIV-2. HIV-1 is responsible for the vast majority of AIDS in the United States. infections. The reuse of disposable syringes and needles for injections is particularly common in certain African, Asian, and Central and Eastern European countries. * In developing countries, additional hazards result from scavenging scavenging of anesthetic. See anesthetic scavenging. at waste disposal sites and manual sorting of the waste recuperated at the back doors of health care establishments. Vaccine waste In June 2000, six children were diagnosed with a mild form of smallpox after they played with glass ampoules containing expired smallpox vaccine smallpox vaccine n. A vaccine containing vaccinia virus suspensions that is inoculated subcutaneously to immunize against smallpox. at a garbage dump in Vladivostok, Russia. The vaccine ampoules should have been treated before being discarded. Radioactive Wastes The public is occasionally exposed to radioactive waste, usually originating from radiotherapy treatments, that has not been properly disposed of. Serious accidents have been documented: In Goiania, Brazil, four people died in 1988 from acute radiation syndrome radiation syndrome Any condition induced by radiation Examples Radiation arthropathy, radiation carditis, radiation cytitis, radiation dermatitis, radiation enteropathy, radiation fibrosis, radiation hepatitis, radiation nephritis, radiation pneumonitis. , and 28 suffered serious radiation burns. Similar accidents happened in Mexico City in 1962, in Algeria in 1978, in Morocco in 1983, and in Ciudad Juarez in Mexico in 1983. Blood Wastes and Chemicals Risks from these wastes have been relatively poorly assessed and need to be investigated. In the meantime Adv. 1. in the meantime - during the intervening time; "meanwhile I will not think about the problem"; "meantime he was attentive to his other interests"; "in the meantime the police were notified" meantime, meanwhile , precautionary measures should be taken. |
