Malaria is a major vector-borne disease in the Indian sub-continent and has been pestering Andaman and Nicobar islands (ANI's) as well since British colonial times. A retrospective data mining technique has been adhered to assess the status of malaria for nineteen years from 2000 to 2019 in ANI's. The altered environment due to 2004 tsunami had increased malaria incidence significantly during (2005-2010). The Nicobar district recorded high incidence of malaria while the least in the north and middle Andaman district. Comparative high incidence of malaria was documented due to than in the Nicobar district between 2005 and 2009. The declining trend of malaria-positive cases in ANI's was observed post 2010, articulating various initiatives taken by the local Andaman and Nicobar administration to curb this vector-borne disease. The initiatives were like (1) large-scale release of larvivorous fish, in the transient water pools, (2) outdoor application of DDT, (3) indoor application of Pyrethrum, (4) malaria awareness drive that led to the curbing of the proliferation not only the malaria vector but also other potential mosquito vector species as well, and (5) implementation of revised drug policy.
疟疾是印度次大陆一种主要的媒介传播疾病,自英国殖民时期以来也一直困扰着安达曼和尼科巴群岛(ANI)。采用回顾性数据挖掘技术评估了2000年至2019年这19年间ANI地区的疟疾状况。2004年海啸导致的环境变化使2005年至2010年期间疟疾发病率显著上升。尼科巴地区疟疾发病率较高,而安达曼北部和中部地区最低。2005年至2009年期间,尼科巴地区记录的疟疾发病率相对较高。2010年后观察到ANI地区疟疾阳性病例呈下降趋势,这表明安达曼和尼科巴地方政府采取了各种举措来遏制这种媒介传播疾病。这些举措包括:(1)在临时水池中大规模投放食蚊鱼;(2)在户外喷洒滴滴涕;(3)在室内喷洒除虫菊;(4)开展疟疾防治宣传活动,不仅遏制了疟疾媒介的繁殖,还遏制了其他潜在蚊虫媒介物种的繁殖;(5)实施修订后的药物政策。
