Dengue and chikungunya
Dengue and chikungunya are viral diseases that are transmitted by the Aedes mosquitoes. These mosquitoes mainly bite during the day.
Most people have no symptoms.
However, some develop a fever, headache, pronounced muscle and joint pains or skin rashes after a few days up to two weeks.
In rare cases, dengue can cause severe symptoms such as shock and life-threatening bleeding.
There is no specific treatment for these diseases.
However, in recent years there have also been several outbreaks in non-tropical regions, such as Southern Europe.
The mosquitoes primarily live in and around buildings in cities, but also in rural areas. There is usually no risk above an altitude of 2000 metres.
