“…This result supports other studies conducted in SP (Wanderley et al 1985, 1994), MG (Chaves et al 1995) and SC (Machado et al 2003). The higher proportion of malaria cases in men may be because they travel to endemic areas to work in high-risk occupations such as mining, farming and timber extraction (Alves et al 2000).…”

“…The greater number of P. falcipa- rum imported cases in these countries has been attributed to the increase in international travel, especially to and from West Africa. Several studies conducted in other extra-Amazonian regions showed different results, with a predominance of P. vivax following the national burden (Wanderley et al 1994, Chaves et al 1995, Alves et al 2000, Bértoli & Moitinho 2001, Machado et al 2003, Falavigna-Guilherme et al 2005, Couto et al 2010, MS/SVS 2013). Moreover, it should be noted that four of the eight cases caused by P. malariae reported in RJ were autochthonous.…”

“…For instance, local malaria cases have been reported in the states of São Paulo (SP) (Wanderley et al 1994, Branquinho et al 1997, Couto et al 2010), Espírito Santo (ES) (Cerutti Jr 2007), Minas Gerais (MG) (Chaves et al 1995), Santa Catarina (SC) (Machado et al 2003) and Paraná (PR) (Bértoli & Moitinho 2001, Falavigna-Guilherme et al 2005). However, there is scarce information about autochthonous malaria in RJ.…”

The lethality of malaria in the extra-Amazonian region is more than 70 times higher than in Amazonia itself. Recently, several studies have shown that autochthonous malaria is not a rare event in the Brazilian southeastern states in the Atlantic Forest biome. Information about autochthonous malaria in the state of Rio de Janeiro (RJ) is scarce. This study aims to assess malaria cases reported to the Health Surveillance System of the State of Rio de Janeiro between 2000-2010. An average of 90 cases per year had parasitological malaria confirmation by thick smear. The number of malaria notifications due to Plasmodium falciparum increased over time. Imported cases reported during the period studied were spread among 51% of the municipalities (counties) of the state. Only 35 cases (4.3%) were autochthonous, which represents an average of 3.8 new cases per year. Eleven municipalities reported autochthonous cases; within these, six could be characterised as areas of residual or new foci of malaria from the Atlantic Forest system. The other 28 municipalities could become receptive for transmission reintroduction. Cases occurred during all periods of the year, but 62.9% of cases were in the first semester of each year. Assessing vulnerability and receptivity conditions and vector ecology is imperative to establish the real risk of malaria reintroduction in RJ.

“…With the aims of finding active cases, conducting entomological studies and applying insecticides, all homes within a five-kilometer radius from the home of the index case were considered to pertain to the focus area. In the event of detecting other possible transmission areas, new five-kilometer radiuses were delineated, totaling an area of 110km 2 . The epidemiological follow-up on the outbreak was carried out over a two-month period, by means of active and passive searches every fifteen days.…”

In March 2005, a resident of the municipality of Monte Alegre de Minas, State of Minas Gerais, without any history of traveling to endemic areas for malaria, was diagnosed with Plasmodium vivax infection and local mosquito-borne transmission was suspected. The epidemiological investigation identified another 10 cases with local transmission and all of them were related to the imported malaria case that was detected in this region. The potential exposure site was the banks of the river Tejuco, an area frequented by mineral prospectors. Some of these prospectors were known to have come from states with malaria transmission. In the autochthonous cases, Plasmodium vivax and Plasmodium falciparum were diagnosed. Entomological investigation identified Anopheles (Nyssorhynchus) darlingi, Anopheles (Nyssorhynchus) albitarsis, Anopheles (Nyssorhynchus) triannulatus and Anopheles (Nyssorhynchus) parvus. After the first outbreak, another three autochthonous cases were notified in municipality of Monte Alegre de Minas, in the same year. The occurrence of these outbreaks highlights the importance of surveillance systems in areas that are nonendemic for malaria.

“…O Estado de Minas Gerais, apesar de não ser considerado atualmente como uma área de elevada transmissão de malária, já o foi no passado 1 e ainda possui relatos de transmissão 3 . A fauna de anofelinos no Estado é elevada e documentada em algumas localidades perfazendo aproximadamente 27 espécies 12 .…”
