Nationwide risk: Protect from mosquitoes due to dengue fever in Sri Lanka
This year, over 160,000 people in Sri Lanka are suffering from dengue fever. There is a risk of transmission across the country. If you want to vacation on the island state in the Indian Ocean, you should therefore protect yourself from mosquitoes.
Dengue fever epidemic in Sri Lanka
Anyone who spends their vacation in Sri Lanka should definitely protect themselves from mosquitoes. Because around 163,760 dengue fever cases have already been reported this year on the island nation in the Indian Ocean, which is “more than three times as many as last year. About 390 people have died, ”reports the Center for Travel Medicine (CRM) on its website. It is the worst outbreak of the dangerous tropical disease in the South Asian country to date.
Disease is transmitted by diurnal mosquitoes
According to the World Health Organization (WHO), around 2.5 billion people worldwide are threatened by dengue viruses. The infectious disease is transmitted in the tropics and subtropics by predominantly diurnal mosquitoes.
The clinical spectrum in the case of an infection ranges from mild forms that are almost symptom-free, to flu-like complaints with fever, headache, muscle and limb pain, to cases in which there is internal bleeding and vascular damage.
Not all infected people develop symptoms of the disease. The complaints usually last about a week. For most of those affected, dengue fever disappears without further consequences.
Vacationers are also at risk. "The number of dengue infections that travelers import to Germany each year is heavily dependent on the epidemiological situation in the countries of infection," writes the Robert Koch Institute (RKI).
In 2015, 722 dengue diseases were reported to the RKI, most of them from Thailand. This also has to do with "that this is a heavily frequented long-distance travel destination."
Protect against mosquito bites
The viral disease also occurs regularly in Sri Lanka. "A transmission risk can be expected nationwide, especially during and after the rainy season," says the CRM.
The western province with the administrative districts of Colombo, Gampaha and Kalutara is currently worst affected. However, the number of new infections has decreased since the beginning of August.
Vaccination against dengue fever is just as little as medication for causal treatment.
To protect yourself from infection, you should avoid mosquito bites. Wearing light, loose clothing and using mosquito nets are options that help to combat annoying mosquitoes.
Above all, the chemical defense is effective. Agents with the active ingredient DEET (diethyltoluamide) are recommended as mosquito repellent. (ad)
