Characteristic fever patterns of malarial infection are clues for diagnosis. However, checking fever patterns in febrile patients has been usually missed, and unnecessary tests have been performed. We reviewed electrical medical record to check whether history-taking included questions on fever pattern in febrile patients.

Microscopy performed on stained films of peripheral blood for detection, identification and quantification of malaria parasites is an essential reference standard for clinical trials of drugs, vaccines and diagnostic tests for malaria. The value of data from such research is greatly enhanced if this reference standard is consistent across time and geography. Adherence to common standards and practices is a prerequisite to achieve this.

Why do better diagnostic tests give false impressions of malaria control?

January 2, 2013 - 13:40 -- William Jobin

Epidemiological Nugget Number Two........Many malaria programs are slowly converting to better diagnostic methods for reporting the prevalence of malaria. However the numbers have to be carefully analyzed, because of the artifacts caused by changes in False Positivity of the better diagnostic tests. The most common diagnostic method used in Africa - and reported through WHO - is called Clinical Diagnosis. This method, relying on the clinical judgement of the health care worker, has a False Positivity Rate of about 80%.
