Bottom Line: The present work offers a critical review of the main estimates undertaken since 1954.It is interesting to note contradictions between textual and graphic information within the same article, variations over time in the work of a same researcher and differences among distinct authors, and that all these issues remain unmentioned or undiscussed.Comparison among such estimates and the data available at the Brazilian Information System on Diseases of Compulsory Declaration (Sistema de Informação de Agravos de Notificação - SINAN) creates an opportunity to identify the degree of imprecision present in those articles, and draws attention to the need for the production of studies at both the regional and national levels, based on concrete data collected at national, state and municipal levels, which has been available on the internet since 2001.

ABSTRACT
Being distant from Brazil's great natural diversity, from its long tradition in the study of snakebites and from the fact that it is one of the few countries which has a national information system for monitoring incidents involving venomous animals, non-Brazilian researchers face risks when estimating the incidence of these accidents in the country. The present work offers a critical review of the main estimates undertaken since 1954. It is interesting to note contradictions between textual and graphic information within the same article, variations over time in the work of a same researcher and differences among distinct authors, and that all these issues remain unmentioned or undiscussed. Comparison among such estimates and the data available at the Brazilian Information System on Diseases of Compulsory Declaration (Sistema de Informação de Agravos de Notificação - SINAN) creates an opportunity to identify the degree of imprecision present in those articles, and draws attention to the need for the production of studies at both the regional and national levels, based on concrete data collected at national, state and municipal levels, which has been available on the internet since 2001.

Mentions: The maps that Kasturiratne et al. present [37] display minimum values of cases and deaths for snakebites. These are reproduced in Figures 4 and 5, respectively. By not taking into account country populations, and consequently being able to calculate the number of incidents per 100,000 inhabitants, the possibility of undertaking comparative analyses among regions and the various estimates becomes more difficult. According to these maps, Brazil is classified into the category that encompasses 10,001 to 100,000 cases and 101 to 1,000 deaths, figures which are much less clarifying than those presented earlier, and which are derived from the authors’ very own tables [37]. This being the case, the relevance and pertinence of these maps should be questioned, since they do not faithfully represent the data presented in the same article.
