FRAYRE-TORRES, María José et al. Mortality from contact with poisonous snakes and lizards in Mexico from 1979 to 2003. Gac. Méd. Méx [online]. 2006, vol.142, n.3, pp.209-213. ISSN 0016-3813.

Objective: To describe the trend of standardized mortality by contact with poisonous snakes and lizards in Mexico from 1979 to 2003. Material and methods: We describe the standardized mortality trend by contact with poisonous snakes and lizards occurring in Mexico from 1979 to 2003, and report the mortality data bases from the INEGI (Instituto Nacional de Estadística, Geografía e Informática). We determined frequencies, percentages, mortality rates, standardized mortality rates and mortality relative risks with 95% confidence intervals. Results: The general trend shows a statistically significant descent of 63.8%. The highest mortality rate within the 2000-2003 period was reported in Quintana Roo (7.47/1 '000,000), Oaxaca (4.01/1 '000,000), Veracruz (1.56/1'000,000), Chiapas (1.48/1'000,000), Campeche (1.43/1 '000,000) and Yucatan (1.29/1 '000,000). The groups with the highest risk are those older than 60 years and males. Conclusions: In spite of the detected decrease in mortality, the contact with poisonous snakes and lizards still is a public health problem in Mexico. As timely treatment saves lives, it is necessary to include and offer treatment in all emergency units of the country.
