Study on The Eco-epidemiology of Chikungunya in U T of Lakshadweep.

An unusual increase in the incidence of viral fever was noticed in Androth and Kalpeni Island, U.T of Lakshadweep during November 2006. The Ecoepidemiology of the disease was studied in detail. The study indicated that Aedes albopictus is the predominant species (98.74%) and it exhibited a wide spectrum of breeding preferences with a clear-cut predilection for rat-damaged coconuts (RDCs). All the entomological indices were very high in both the Islands with a marked increase in Kalpeni Island. The clinical presentation of the cases was typical of chikungunya and the laboratory study confirmed this. Based on the investigation, control and preventive measures were planned, advised and implemented. The details regarding the bio-ecology of vectors, clinical presentation, laboratory investigations and effectiveness of control measures are discussed.

Awareness of health personnel about lymphatic filariasis and mass drug administration in Kerala State.

The mass drug administration programme to eliminate lymphatic filariasis with DEC in Kerala was started in 1997, extended to all the 11 endemic districts by 2005. Since the beginning of Mass drug Administration, the drug consumption rate was found to be not satisfactory. The reasons for noncompliance indicated that the community is not fully convinced about the programme. The knowledge of the medical and para medical workers is certainly a factor in the success of implementation of the programme and is vital. To ascertain the knowledge, a study was undertaken and found not satisfactory. Hence intensive training on all aspects of lymphatic filariasis and the Mass drug Administration programme to achieve the requisite drug consumption rate to meet the goal is needed.

Study on the factors affecting the MDA programme in Kerala state.

The Mass Annual Single dose DEC administration (MDA) was initiated in India from 1997. In Kerala MDA was studied as a pilot project in Alappuzha and Kozhikode District from 2000-04 and the first round of MDA was launched in Kerala covering eleven endemic districts, in March 2005. On evaluation, the drug distribution coverage, compliance, etc. were found to be not satisfactory and a need to elicit the factors for poor performance of MDA is felt essential. The main reasons for poor performance of MDA in Kerala state were the lack of adequate prior information to the target population regarding the importance LF elimination programme and inadequate awareness. The fear of side reactions, antipropagonda, poor IEC activities repeated postponement of programme, insufficient time for mobilisation etc. were the other reasons for poor compliance. The purpose of the present study was to bring the observations to the notice of the authorities so that appropriate remedial measures are incorporated.
