Malariometric parasitological survey in El-Fayoum Governorate, Egypt.

Egypt represents the only focus in the Mediterranean region where Plasmodium falciparum transmission still occurs. A total number of 9065 individuals of different ages of both sexes were examined. 7236 (79.82%) individuals examined during (MBE) i.e. house-to-house visit; 1184 (13.06%) individuals examined by (PCD) i.e passive case detection; and 645 (7.12%) individuals represented (NOD). The total number of positive cases was 52. Out of them, two only were P. vivax. But, the rest were P. falciparum, 32 cases (61.54%) were detected by MBE, 12 cases (23.08%) by PCD and 8 cases (15.38%) by NOD. The mean age of the total positive cases was 20.54 +/- 14.93 years. It was found that malaria infection didn't get affected by sex. The parasite rate (PR) among was 0.57%, parasite formula was 96.15% for P. falciparum and 3.85% for P. vivax, species infection rate (SIR) was 0.55% for P. falciparum and 0.02% for P. vivax. Gametocytaemia was 74% of the total positive malaria cases. High parasite density (PD) was encountered among the younger age groups less than five years.
