Two new cases of smallpox (MPOX) have been detected in Réunion, the Regional Health Agency (ARS) announced on Monday. These infections are linked to the second imported case from Madagascar, confirmed on February 9. The two individuals live in the same household. Since the beginning of the year, four cases have been recorded on the island.
In response to the spread of the virus in the Indian Ocean region, particularly in Madagascar, the Regional Health Agency (ARS) launched a preventive vaccination campaign on February 9th targeting the most at-risk groups: travelers to high-risk areas, healthcare professionals, immunocompromised individuals, sex workers, and people with multiple sexual partners. Vaccination is also offered to close contacts after exposure, ideally within four days of the potential exposure.
Vaccination and enhanced prevention measures
The injections are administered by appointment at three vaccination centers on the island. The schedule involves two doses, four weeks apart, with protection considered acquired two weeks after the second injection. Only one dose is required for individuals who were vaccinated against smallpox in childhood.
Mycox primarily manifests as a skin rash or mucous membrane ulcers, sometimes accompanied by fever, headache, and swollen lymph nodes. Transmission mainly occurs through close contact with an infected person, via skin lesions, mucous membranes, or contaminated objects. The Regional Health Agency (ARS) recommends that anyone experiencing suggestive symptoms, particularly upon returning from an area with active virus transmission, contact a doctor or emergency medical services (SAMU 15) immediately and self-isolate while awaiting medical advice.
