True versus apparent malaria infection prevalence: the contribution of a Bayesian approach.

Aims: To present a new approach for estimating the "true prevalence" of malaria and apply it to datasets from Peru, Vietnam, and Cambodia.

Methods: Bayesian models were developed for estimating both the malaria prevalence using different diagnostic tests (microscopy, PCR & ELISA), without the need of a gold standard, and the tests' characteristics. Several sources of information, i.

[Efficiency and specificity of the KAT-test for rapid diagnosis of falciparum malaria].

A new rapid KAT Quick Malaria test for the diagnosis of falciparum malaria, which is based on the detection of a monoclonal antibody-antigen complex of malaria parasites, has been worked out by the KAT Medical CC in South Africa. The efficiency and specificity of the KAT test were compared with those of the microscopic method and with the ICT test for rapid diagnosis of P. falciparum and P.
