[Frequency of malaria relapse due to Plasmodium vivax in a non-endemic region (São Paulo, Brazil)].
Very few well-established information is available about the frequency and timeliness of relapses in cases of Plasmodium vivax malaria acquired in Brazil. So, we analysed a series of correctly treated patients observed out of endemic areas. The rate of relapses seen in São Paulo, which may represent that of the parasitosis in the whole country, was high, ranging from 7.5% to 24.5%, and early in most cases, i.e. appearing by three months, what anticipates a high endemicity.
