Coccidiomycosis cases.

A significant increase in coccidiomycosis cases in Arizona between 1998 and 2001 is attributable to climatic factors, an investigation revealed.

In 1998 there were 33 cases of the disease, also known as valley fever, per 100,000 population; in 2001 there were 43 cases per 100,000 population. The disease has previously been linked to soil disruption, construction, and even earthquakes. In this study, certain climatic and environmental factors (particularly hot and dry conditions) were strongly associated with outbreaks, Benjamin J. Park, M.D., of the Centers for Disease Control and Prevention, Atlanta, and his colleagues reported.

Known risk factors for infection were not significantly more prevalent during the high- vs. low-incidence periods, the investigators noted (J. Infect. Dis. 2005;191:1981-7).

The findings could help public health officials predict seasonal outbreaks of the disease, which is associated with considerable morbidity and a substantial public health burden and allow for the use of appropriate preventive measures, they concluded.
