Malaria in Indian Perspective: A Review
Abstract: Malaria is in its pre-elimination stage in India. It is particularly widespread in low-income rural areas of eastern and northeastern states. In this scenario, community-based strategies are important for malaria control. In order to intensify elimination activities, we need to have a better awareness of malaria in the rural areas. Though there are facilities available in the urban population, due to unhygienic surroundings of slum areas, increase in the waste …
