SIMPLE METHOD TO CONTROL BRUGIA-TIMORI BY DIETHYLCARBAMAZINE ADMINISTRATION

The results of mass treatment using 50 mg diethylcarbamazine per kg body-weight followed one year later by short term selective re-treatment in a highly endemic area of Brugia timori are described. The criteria for selection of re-treatment are simple and practical for use in rural areas. The microfilaria rate by finger prick decreased from 24% to 0 and by NucleporeR filtration from 30% to 2·5%. The disease rates were also affected favourably. 88% of persons receiving the drug reacted to treatment, this percentage slightly exceeding the total filarial infection rate (71%). The prevalence, onset, duration and nature of side reactions are briefly discussed and related to the presence of microfilaraemia and disease manifestations among the study population. © 1979.
