Prevalence of bancroftian filariasis in Burdwan district, West Bengal: II. Vector and microfilariae density in colliery and non-colliery areas.

The paper reports the density of Culex quinquefasciatus, infection and infectivity rates, microfilariae(mf)- density and microfilaraemic persons in the colliery and non-colliery areas of Burdwan district, West Bengal. The numbers C. quinquefasciatus were significantly higher in colliery areas, as compared to non-colliery areas. The infection rate and infectivity rates of the vector were found to be higher in colliery areas. The higher vector density in colliery area is one of the major reasons of higher prevalence of filariasis in that area. However, other environmental factors like exposure of the host to the coal might influence the pathogenesis of filariasis in the colliery area.

Efficacy of a single dose treatment of Wuchereria bancrofti microfilaria carriers with diethylcarbamazine in Matara, Sri Lanka.

OBJECTIVE: To test the efficacy of diethylcarbamazine DEC single dose regimen of 6 mg/kg body weight (bw) on a sample of Wuchereria bancrofti microfilaria (mf) carriers in Matara. DESIGN: 6 mg/kg bw DEC dose in 50 mg tablets given under direct observation to the subjects at 23.00 hours after pre-treatment blood collection for mf counts. Post-treatment mf counts were at 1, 2 weeks and 1, 3, 6, 12 months. SUBJECTS: 31 asymptomatic mf carriers, 14 males, age range 6 to 62 years. RESULTS: Treatment resulted in 89 to 97% success rate, 19 to 28% cure rates and 74 to 80% reduction in mf density. There was no difference statistically in the success rate and cure rate at 6 and 12 months. The effect of DEC treatment at 6 and 12 months compared by sex, age group and pre-treatment mf level showed no difference. 64.5% of the carriers treated had at least one mild adverse reaction. Rates of the common reactions were 41.9% fever, 22.6% headache and 16.1% joint pains. CONCLUSION: A new mass treatment program has been initiated by the national Antifilariasis Campaign using the single dose DEC 6 mg/kg bw regimen. The satisfactory reduction in mf density at 6 and 12 months following DEC single dose treatment we observed provides support for this program.
