Tiger mosquitoes and dengue fever: what's the situation in Switzerland?
Content-Team SWICA
Transmission and symptoms
It generally takes four to seven days for any symptoms to develop after being bitten by a tiger mosquito that is carrying the dengue fever virus. In many cases the victim shows no signs of illness at all – it is asymptomatic. In 20 to 60% of cases, however, they will experience symptoms such as high fever, headache and aching limbs or a rash. Some people may get a more severe type of dengue with bleeding, liver damage and, in the worst cases, circulatory failure – but this is rare. There isn't yet any specific treatment for dengue fever. Patients are treated with pain relief and fever-reducing medication.
No cases of transmission in Switzerland
The good news is that no one has yet caught dengue fever within Switzerland. All known cases of the disease have occurred in travellers who have been bitten abroad, become infected and returned to Switzerland with the fever. The bad news is that because both the number of infected travellers and the prevalence of tiger mosquitoes is growing, the risk of transmission in Switzerland is also increasing. If a tiger mosquito bites an infected person, it can pass the virus contained in their blood to the next person, thereby spreading dengue fever.
How can we stop the spread of the tiger mosquito?
The tiger mosquito lays its eggs in places where water collects, such as water butts or plant pot saucers. So it's important to avoid standing water in our gardens or on balconies, to prevent the mosquito from breeding. Water that has a moving surface, such as s swimming pool, is fine. Various measures are being taken to try and halt the spread of the tiger mosquito in Switzerland. Anyone who spots a tiger mosquito should report it here.For your health: santé24 and SWICA Benecura
