Dengue fever in Europe: how you can protect yourself effectively

The distribution of dengue fever is increasingly a risk for travelers, especially in regions that have become popular holiday destinations. An expert in travel medicine explains how important it is to protect yourself from an infection to minimize health risks.

growing threat from dengue fever

In recent years, the number of dengue cases has increased worldwide, which is on alert. The virus, which is transferred through the Asian tiger mosquito (Aedes Albopictus), is no longer limited to tropical countries. In the spring of 2024, record numbers of infections were reported in Brazil, which the health authorities alerted. In Italy, especially around Lake Garda, more outbursts are also documented.

The most important thing: insect protection and medical advice

Frieder Schaumburg, director of the Institute for Medical Microbiology and Head of Travel Medicine Vacation Consultation at the University Hospital Münster, emphasizes that travelers can protect themselves with two simple measures: the use of mosquito sprays and vaccination. The sprays should contain ingredients such as deet or icaridine that have proven to be particularly effective against mosquito bites.

Vaccination against Dengue fever: a controversial decision

The constant vaccination commission (STIKO) currently does not recommend vaccination as a use of travel against dengue fever, since there can be considerable complications if there are already antibodies. The phenomenon of the "antibody branch enhancement" could lead to vaccination increasing the risk of severe disease courses if the traveler later develops to dengue. Experts warn of such a vaccination without medical advice.

Identify endangered travel destinations

When trips to tropical countries such as Thailand, Brazil or Mexico are planned, Schaumburg advises travel medical advice. Individual protective measures can be developed here. Popular travel destinations affected by Dengue cases include:

• Brazil
• Argentina
• peru
• chile
• Colombia
• Costa Rica
• ecuador
• Mexico
• Hawaii
• Thailand
• Vietnam
• Bali
• Singapore
• Malaysia

Symptoms recognize and act

The early detection of dengue infection can be a challenge, since the symptoms are often unspecific. Frequent signs are fever, body aches and fatigue as well as a rash. After a stay in tropical regions, it is important to see a doctor if such symptoms appear to have possible infections clarified, including malaria, which can occur in a similar way to travelers.
