Health authorities on Réunion Island have confirmed two new cases of mpox, also known as monkeypox, bringing the total number of confirmed infections on the French overseas department to four since the start of the year.
Household Cluster Linked to Imported Case
According to a statement released Monday, February 23, by the Regional Health Agency (ARS) of Réunion, the two new patients are linked to a second case imported from Madagascar that was confirmed on February 9. The agency specified that both individuals reside at the same address, indicating a household cluster of the viral infection.
Preventive Vaccination Campaign Launched
In response to the observed circulation of the virus in the Indian Ocean zone, particularly in Madagascar, the ARS launched a preventive vaccination campaign on February 9. The campaign targets the most exposed groups, including:
- Travelers to areas with active virus circulation who may have potential risk exposures.
- Individuals with multiple sexual partners and sex workers.
- Healthcare professionals at risk of exposure.
- Immunocompromised persons.
Vaccinations are available by appointment at three centers on the island. The vaccine regimen involves two doses administered four weeks apart, with full protection considered effective two weeks after the second injection. Only one dose is required for individuals previously vaccinated against smallpox in childhood.
Symptoms and Public Health Advice
Mpox is a viral infection that primarily manifests through a skin rash or ulcerations of the mucous membranes, sometimes accompanied by fever, headache, and swollen lymph nodes. Transmission occurs through close contact with the lesions or mucous membranes of an infected person, or via contact with contaminated objects.
The ARS reiterates that anyone showing suggestive symptoms, especially travelers returning from Madagascar or other active virus circulation zones, should promptly contact their doctor or emergency services and self-isolate while awaiting medical advice.
