Objectives To study clinical aspects of the 2001 outbreak of malaria at Medical Officer of Health Division, Mawanella and to analyse the incidence in subsequent years.

Design & Setting A prospective study of all blood film positive malarial cases presenting to the Base Hospital, Mawanella from June to September, 2001 and in subsequent years.

Method Data was collected from the Register of Anti-Malarial Campaign, Microscopy Service, Mawanella, Bed Head Tickets, interviewing patients and visiting the area.

Results During outbreak a total of 366 malaria infections were detected and 120 patients (32.78%) were in the paediatric age group (0-14 years). Of the infections, 277 (75.68%) were due to Plasmodium vivax and 89 (24.32%) to Plasmodium falciparum. Emergence of P. falciparum was detected by the Antigen Test. During this 4 month period a significant number of children had repeated infections mostly due to relapse with P. vivax or reinfection with P. falciparum. Two children were treated with quinine. A very low incidence of malaria was observed in the four subsequent years.

Conclusions Outbreak of malaria should be expected when suitable climatic and geographical conditions prevailed in wet zones. Antigen Test is important in identifying species in difficult cases. Low incidence.  

Key words: Plasmodium falciparum, antigen test, drug resistance
