WHILE (Alert): cases of dengue hemorrhagic fever (DHF) in the province of North Sumatra (North Sumatra) have increased.
North Sumatra Health Service (Kadiskes) chief drg Ismail Lubis MM said the number of dengue cases in 2020 reached 3,192 people, in 2021 cases dropped to 2,918 people. Then, from 2022 to August, the cases rose to 4,856 people.
“Compared to 2020-2021 (the Covid-19 pandemic), the cases are increasing. However, compared to 2019 and before, the increase in cases until August is still lower than that year, “said Ismail Lubis on Thursday (15/9).
However, he said his party is still making efforts to reduce the number of dengue cases, among other things by sending circulars on the appeal for the implementation of preventive and preventive measures, distributing the DHF Rapid Diagnostic Test (GDR). for early diagnosis of cases.
Provide guidance in the epidemiological analysis of rising DHF cases to districts / cities. Carry out epidemiological investigations (PE) to increase dengue cases in districts / cities.
Thus, advocating with the local government has indicated an increase in dengue cases. Conducting fogging in locations that have the potential for dengue transmission and investigating dengue vectors.
When asked about current weather conditions, about the development of the Aedes Aegypti mosquito, he said that only female mosquitoes can spread the dengue virus (and they can also carry Zika, Chikungunya and yellow fever viruses).
In tropical climates, especially when it enters the rainy season because it makes the environmental conditions very favorable for the reproduction of mosquitoes. It has an anthropophilic nature, in the sense that it prefers to suck human blood. Black and white stripes all over the body and small in size.
It can fly up to 100 meters and up to 400 meters, so the spread of the virus can occur up to long distances from where mosquitoes nest. Happy in clean, clear water i.e. water tanks, such as bathtubs, flower pots and gutters, pet water drinking places and refrigerator / dispenser water disposal.
He loves hiding in corners of the room that lack sunlight, while outside the home he loves hollows in trees that are flooded with water. Active biting from morning to evening is the most active time to search for prey around two hours after sunrise and several hours before sunset.
Multiple feeding which can suck blood multiple times at a time until the mosquito is full so it can pass the virus to more than one person at a time. The typical jentingnya usually actively moves from the bottom to the top of the water surface repeatedly.
The most effective steps to prevent DHF that can be taken by the community are to keep the house and environment clean so that it does not become a nesting place for Aedes Aegypti mosquitoes by carrying out the 3M movement (closing water tanks, drainage bathtubs, recycling of used goods) in addition to the use of mosquito repellent lotions, installation of wire mesh and use of mosquito nets, planting mosquito repellent plants such as lavender.
“If not done simultaneously and jointly by all levels of society and stakeholders (cleaning services, settlements, education, district / lurah / village heads and others), dengue cases will continue to increase in North Sumatra.” he concluded. (cbud)
