Malaria survey at Humera, northwestern Ethiopia.

Any attempt to control malaria in a locality should be preceded by an evaluation of the magnitude and conditions of transmission of the disease. A malaria survey was carried out at Humera, Northwestern Ethiopia from September 5 to 25, 1991 because no information was available regarding the malaria situation in the area for the last two and half years. The present survey was carried out as soon as the area was made accessible. The results showed a splenomegaly rate of 18.8% and parasite rate of 10.9% in children aged 2 to 9 years. These results correspond to mesoendemic malaria transmission of unstable malaria. This survey is the beginning of a series of follow-up studies to arrive at the final conclusion about the endemicity of the disease in the area.
