Lymphatic filariasis remains a significant public health problem in many rural areas of India due to limited awareness, misconceptions, and inadequate preventive practices. The National Service Scheme (NSS) provides a vital platform for community-based health interventions through student participation. The present study aimed to assess the impact of an NSS-led survey followed by an awareness drive on filariasis prevention in an adopted village. A survey-based qualitative research design was adopted for the study. Data were collected from 100 villagers using a semi-structured interview schedule focusing on awareness, knowledge, attitudes, and preventive practices related to filariasis. Following the baseline survey, NSS volunteers conducted an awareness drive through health talks, interpersonal communication, and distribution of informational materials. The qualitative responses were organized into themes and sub-themes, and results were presented using frequency and percentage analysis. The findings revealed that while a majority of respondents had heard about filariasis, substantial gaps existed in knowledge regarding its causes, transmission, and government prevention programmes. Awareness about Mass Drug Administration (MDA) was notably low. Post-awareness intervention, a significant improvement was observed in participants’ understanding of mosquito-borne transmission and preventive measures. Increased acceptance of mosquito control practices and positive attitudes toward prevention were also reported. The study concludes that NSS-led surveys combined with structured awareness drives are effective in enhancing community knowledge and promoting preventive behaviors against filariasis. Such student-led initiatives can play a crucial role in strengthening grassroots-level public health interventions and supporting national filariasis elimination efforts.
