Potential of rainfall, humidity and temperature, against the increasing of larvae in makassar city, Indonesia

Abstract

Cases of dengue hemorrhagic fever are associated with the potential for rainfall, temperature, and humidity. In a month mosquitoes can lay eggs approximately four times. In a month mosquitoes can lay eggs between 400 to 600 eggs. Mosquito eggs can survive, do not hatch, for six months because they do not touch the water. The existence of rainfall, humidity, and the appropriate temperature can accelerate the process of hatching mosquito eggs. Secondary data analysis research methods on BMKG data and Makassar City Health Department data in 2014, 2015, 2016, 2017 and 2018. The data analysis was carried out on 1–8 October 2019. The observation results revealed that high rainfall occurred in January, February, March, April, May and June. In July, August, September the rainfall is very low. Then entering November and December, the rainfall starts to high again. Air temperature does not occur significantly or not too extreme a difference every month. Humidity in the rainy season tends to be high. The incidence of dengue fever in the rainy season tends to increase. The number of mosquito larvae also tends to increase in the rainy season. It is recommended that before entering the rainy season, it should increase awareness of the incidence of dengue fever by reducing mosquito breeding sites through draining, closing, stockpiling. Drain and close the bathtub, and bury cans, plastic, and objects that can become mosquito breeding grounds.
