Chikungunya, dengue and Zika: the role of health professionals

2024-06-06 22:00:00

Dengue, chikungunya and Zika viruses are typical tropical diseases caused by arboviruses. They are regularly imported into French territory by travelers (imported cases), where they can be transmitted by tiger mosquitoes (Aedes albopictus). The mosquito-borne activity period for these diseases began on May 1, and since 2023, there has been a sharp increase in dengue cases imported into the region. effect. In fact, informing patients, including travelers, about preventive measures, early diagnosis and reporting of these diseases can reduce the risk of local transmission chains (indigenous cases). That is why the French Public Health Agency has provided health professionals with a practical guide describing these elements and the main prevention information to give to patients with dengue, chikungunya or Zika virus.

Health professionals: a central role in the system

Health professionals play an important role at multiple levels of arbovirus surveillance and control systems, in particular through:

Disseminate personal prevention messages to patients, especially the correct actions to avoid mosquito bites; report cases to the Regional Health Service (ARS) so that investigations can be initiated and guidance on mosquito control; measures.

Reporting also allows for measures to be taken to ensure the safety of human products if a local outbreak occurs.

How do I report these illnesses?

Chikungunya, dengue and Zika are notifiable diseases and must be notified year-round. The CERFA forms to be filled out can be downloaded from our website denguethis Chikungunya and Zika virus.

Tiger mosquitoes are particularly active in much of France between May and November, so monitoring is intensified. During this period, early reporting of cases is critical to reducing the risk of local transmission.

Report each case immediately to your area’s ARS Regional Surveillance and Health Emergencies Platform.

What’s the situation like in mainland France?

The risk of local transmission in mainland France is real, with a few cases detected every year. Additionally, increased transmission has also been seen over the past two years.

This risk becomes more severe in 2024 due to an unprecedented number of confirmed imported cases, largely related to the ongoing dengue epidemic in the French West Indies.

Weekly updates are published on our website, allowing us to track changes in case numbers.
