ANALYSIS ON CURRENT SITUATION OF MALARIA IN NANQIAO TOWNSHIP, A MOUNTAINOUS AREA OF HAINAN PROVINCE

In 1994 - 1995, an investigation onthe malaria annual parasite incidence (API)and theprevalence was conducted in Nanqiao township toaid in further understanding of the malaria currentsituation and related endemic rule in the mountainous areas of Hainan province. As a result, the APIin 1994 and 1995 were 3.52% and 3 - 53% with afalciparum malaria API of 0. 96 % and 1. 16 %, respectively. The proportion of villages with an APIof >5 .0% (average 8.70% ) was 22.0%;and 1. 1- 5.0% (average 2.69% ), 45-8%; and 0.11.0% (average 0.72% ), 15.2%; and zero,16.9% . Thfference between villages in malariaprevalence depending on its topography and amountof people who stay overnight in mountain.

The seasenal peak of both vivax and falci parum malaria was from May tc September. A sur vey based on five high risk villages showed thattheAPI was 10. 34% (range 7 .78 - 17 .71 % ) dur ing from January of 1994 to May of 1995, while theparasite rate waS 7 .44% (range 2 .43 - 13. 08% )in June of 1995.
