Abstract
Findings in a sample population in SE Peru with a very high rate of malaria infection, due to P. malariae and P. vivax with apparently no P. falciparum, are described. The proportion of persons with P. malariae in this sample population, as determined by slide examination, appears to be the greatest ever reported for any area before the introduction of control measures. Although very few P. vivax were found on stained slides, results of the indirect immunofluorescence test indicated that this species was probably as prevalent as P. malariae; the absence of P. falciparum was supported by results of serologic tests. Possible reasons for this focus of malaria with no P. falciparum are discussed.
