Dengue hemorrhagic fever is a viral infection that is carried through mosquito bites. This disease is most commonly found in tropical regions, including Indonesia. Cases of dengue hemorrhagic fever (DHF) are most common in areas with high population density such as Bali and East Kalimantan.
Recognizing areas that are vulnerable to dengue can make you more careful if you are occupying an area, intend to occupy an area, or travel to these areas.
DHF Prone Areas in Indonesia
Indonesia is one of the countries with the highest DHF cases in Southeast Asia with the incidence rate (IR) of DHF tends to increase from year to year.
Based on 2016 DHF IR data per province owned by the Ministry of Health, the following are the three provinces with the highest morbidity rates: Bali, East Kalimantan and DKI Jakarta. While the provinces with the lowest occurrence in 2016 are: West Papua, West Kalimantan and East Nusa Tenggara. The number of deaths due to DHF throughout Indonesia in 2016 reached 1585 cases with the highest death cases found in the province of East Java.
If you live or intend to travel to this area, it is recommended to be more careful in protecting yourself from mosquito bites. Some regions, such as Maluku, have high mortality rates even though the sickness rate is the lowest among other provinces. Of all the dengue cases that occurred in Maluku, as much as 6 percent resulted in death.
The mortality rate due to DHF in each region is certainly different. But overall, the death rate (Case Fatility Rate / CFR) due to DHF in Indonesia has fallen significantly since the beginning of the DHF case in Indonesia. Part of this is due to improved medical treatment, more adequate health facilities, and increased public awareness.
The number of cases of disease transmitted by Aedes aegypti mosquitoes tends to be high in places where conditions are dominated by the following factors:
Mosquito populations generally increase in the rainy season. High rainfall is the best habitat for dengue-carrying mosquitoes to breed. But in Indonesia, mosquito breeding occurs almost throughout the year. This is because the behavior of residents who tend to be less maintain the cleanliness of their homes, such as letting a pile of used goods, so it becomes a breeding ground for mosquitoes. In addition, throughout Indonesia four types of dengue virus have developed that continue to circulate throughout the year.
Data from the Ministry of Health revealed that most dengue cases occur in cities with high population density such as on the island of Java. This density is exacerbated by inadequate infrastructure such as waste collection and disposal facilities, as well as reservoirs of clean water.
In addition, the behavior of residents to collect water in reservoirs without maintaining cleanliness makes these containers an ideal location for larvae to breed. These conditions cause mosquitoes to breed throughout the year.
Health facility factors
The existence of fogging or fogging equipment is not accompanied by maintenance and repair costs so that its use is not optimal. In addition, it is also feared that resistance to insecticides will be used for smoking.
Recognizing the factors that cause an increase in dengue cases as well as high-risk areas can make you more alert for this disease. Now to facilitate the monitoring of mosquito larvae to support the control of DHF, there are applications that you can use, namely Pokentik. This application can help eradicate mosquito larvae.
Take precautions, such as maintaining environmental cleanliness and avoiding yourself from mosquito bites, is very beneficial in reducing the risk of contracting dengue.
