Abstracts

Thick blood films and malaria indirect fluorescent antibody test (P. falciparum and P. vivax) were done in four different regions in Amazonas. There was a very low prevalence of parasites anã the antibody rates suggest a small amount of transmission and that P. vivax was the predominant parasite. The calculation of probability of being infected per year was about 8% in Tefé. Coari, Colonia Fernanão Costa and Labrea and 0.8% in Anori.

ABSTRACT

Thick blood films and malaria indirect fluorescent antibody test (P. falciparum and P. vivax) were done in four different regions in Amazonas. There was a very low prevalence of parasites anã the antibody rates suggest a small amount of transmission and that P. vivax was the predominant parasite. The calculation of probability of being infected per year was about 8% in Tefé. Coari, Colonia Fernanão Costa and Labrea and 0.8% in Anori.

RESUMO

Os autores fizeram pesquisa de hematozoário e reação de imuno-fluorescência indireta (P. vivax e P. falciparum) em 922 pessoas vivendo em Tefé, Coari, Anori, Colônia Fernando Costa (Roraima) e Lábrea. Verificaram que a transmissão da malária era baixa e que havia preãominância do P. vivax. Calcularam que a probabilidaãe de se infectar em um ano era ãe 8% em Tefé, Coari, Colônia Fernanão Costa e Lábrea e ãe 0,8% em Anori.
