RESUMEN
We performed a cross-sectional study of Trypanosoma cruzi seroprevalence in 14 communities in three provinces of Ecuador and estimated the magnitude of the association of seropositive individuals within households. A total of 3,286 subjects from 997 households were included. Seroprevalence was 5.7%, 1.0%, and 3.6% in subjects in the Manabí, Guayas, and Loja provinces, respectively. Seroprevalence increased with increasing age in Manabí and Guayas, whereas in Loja, the highest prevalence occurred in children Asunto(s)

RESUMEN
This survey evaluated tobacco use of migrant tobacco workers in eastern North Carolina. Sixty-nine (38%) out of 181 mostly male, Mexican farmworkers were smokers. Compared to non-smokers, three times more smokers reported alcohol use in the past week (p=0.002). More smokers compared to non-smokers reported poor to fair health, and fewer had worked previously in tobacco agriculture, but these differences were not statistically significant. Also not statistically significant, those smokers who were older and those who understood the most English smoked more cigarettes per day. Because farmworkers are exposed to many non-tobacco respiratory irritants, and because of the health risks of smoking, those who smoke should be urged to quit.

BACKGROUND: Green tobacco sickness (GTS) is a highly prevalent occupational illness among tobacco workers. Working in wet tobacco is a major risk factor for GTS. Little is known about preventing GTS. This analysis examines possible GTS preventive measures. METHODS: Data were collected from 36 patients with GTS and 40 controls who presented at clinics in eastern North Carolina in 1999 and 2000. Each participant completed an interview that included questions about their personal characteristics, work characteristics, and GTS risk factors. RESULTS: Participants were Mexican men. Those with GTS were much less likely to have worn rain suits while working in wet tobacco and more likely to be in the United States on a work contract. CONCLUSIONS: Wearing a rain suit while working in wet tobacco can significantly reduce the risk of GTS among tobacco workers. Care must be taken that farmworkers do not have heat stress from wearing rain suits.
