How did malaria spread in south Asia?

Answer 1

malaria spread in South Asia primarily through the Anopheles mosquito, which acts as the vector for the Plasmodium parasite. Factors such as monsoon rains, which create breeding habitats for mosquitoes, along with population movement, urbanization, and inadequate healthcare infrastructure, have facilitated its transmission. Additionally, environmental changes, like deforestation and irrigation practices, have contributed to the proliferation of mosquito populations. Efforts to control malaria have included the use of insecticide-treated bed nets, indoor spraying, and antimalarial medications.
