RESUMO
During 1983, a multinational military intervention took place on Grenada. After deployment, troops from several U.S. Army units noted signs and symptoms consistent with soil-transmitted helminthic infection. Of 684 soldiers screened five to seven weeks post-development, over 20 percent reported abdominal pain and/or diarrhea during or after the action. Eosinophilia of at least 10 percent was observed in 119 (22.5 percent) of 529 soldiers evaluated further; eosinophilia of 5-9 percent was documented in another 126 (23.8 percent) of the 529 soldiers. Stool examinations confirmed hookworm infection in 35 soldiers. One case of strongyloidiasis was also documented. Infection was attributed to ground exposure near homes with compromised sanitation. Units that joined the operation after the initial assault phase were at low risk of hookworm infection. (AU)
