MALARIAL SURVEY IN DIFFERENT EPIDEMIOLOGICAL ZONES IN NIGER DURING THE RAINY SEASONS
S. Hamani Boureima

SUMMARY
An update of our knowledge concerning malaria would appear to be necessary when recent epidemiological developments along with the need to reinforce the evaluation capabilities of endemic malaria in Niger are taken into account.
Within this context, a small number of representative sites were chosen in order to carry out our study which consisted of a parasitological examination of blood, the measurement of body temperature and a clinical examination of the spleen.
As a result, the prevalence of malarial infection was shown to be high and there were no major differences between villages during this rainy season. Plasmodium falciparum was the predominant strain, followed by Plasmodium malariae.
The main objective of this study was the on-site compilation of several epidemiological indices in order that all health professionals concerned would themselves be updated, which would help them in their investigations. To this end we retained the following parameters for the subsequent analysis: age, sex and blood parasitology findings; the measurement of temperature and the splenic index not having any influence on the results.
