OUTBREAK OF FALCIPARUM MALARIA IN SUBMERGED VILLAGES OF NARAYANGANJ PHC, DISTRICT MANDLA DUE TO NARMADA IRRIGATION PROJECT, CENTRAL INDIA (MADHYA PRADESH)

摘要

On receipt of a report about high prevalence of malaria and deaths inn submerged villages of Narayanganj Primary Health Centre (PHC) of district Mandla, Central India (Madhya Pradesh) due to Bargidam in October-November 1996, an investigation into the causes was carried out in 20 villages. Blood smears from fever cases and contacts of deceased patients were collected. Slide positivity rate was over 70%, of which more than 90% was Plasmodium falciparum. Mass blood surveys of infant and pregnant women revealed 39% and 62% parasite prevalence rate respectively. More than 80% children (2-9 yrs) had enlarged spleen. Such high malaria prevalence appeared to be maintained by Anopheles culicifacies and An. fluviatilis which could not be suppressed by intensive surveillance, prompt radical treatment with 1500 mg chloroquine and 45 mg primaquine and two rounds of special focal spray with DDT in October 1996 and January 1997, There is, therefore, an urgent need to develop suitable malaria control strategy by replacement of insecticides in conjunction with prompt and effective radical treatment.
