Aedes aegypti mosquito vector disease susceptibility index, environmental factors in Parvathipuram Manyam District, Andhra Pradesh, India

Dengue Hemorrhagic Fever (DHF) is common in the Parvathipuram Manyam District of Andhra Pradesh, India. According to the Public Health Office in the district headquarters, there has been an increase in dengue cases at Parvathipuram Manyam Community Health Center over the past six months of 2022. The dengue virus, which causes dengue hemorrhagic fever, is transmitted by the Aedes aegypti mosquito. If DHF is not treated immediately, it can be fatal. Over the last five years, the Parvathipuram Manyam district of Andhra Pradesh, India, has seen an increase in dengue fever cases. The incidence rate will have an impact on the community health development index and general health status in Parvathipuram Manyam. The goal of this study was to determine how vulnerable the Parvathipuram Manyam district was to dengue fever using the disease vulnerability index. The methodology used to calculate the Village Development Index was investigated. The index of environmental disease vulnerability is divided into seven categories and 23 sub indicators. The district is at an intermediate level of risk, with a DHF vulnerability index score of 2.771. If this condition is not addressed and significant preventative measures are not implemented, it has the potential to become extremely vulnerable in the coming year. Addapuseela was the most vulnerable village, with a value of 3.348, while Parvathipuram was the least vulnerable, with a value of 2.304. According to the findings, every village in the Parvathipuram Manyam district is vulnerable in some way. True and effective efforts on the part of all parties involved, particularly the Community Health Center and the surrounding community, are required to prevent and manage the underlying causes of DHF disease. This is critical if we are to see a decrease in DHF cases and, eventually, its abolition. Using the chi-square test, the statistical analysis produced a p-value of 0.666, indicating that p> 0.05. Hence, there exists a correlation between behavioral factors and the incidence of DHF.
