Mpox Resurgence in Réunion: What the Latest Cases Inform Us
Two new cases of mpox (formerly known as monkeypox) have been detected in Réunion, bringing the total confirmed cases for 2026 to six. These developments, announced by the Regional Health Agency (ARS) La Réunion, highlight the ongoing global circulation of the virus and the importance of preventative measures.
Understanding the Recent Outbreak
The latest cases are linked to a previously imported case from Madagascar, confirmed on February 9th. One of the new cases is a contact of that individual. Notably, the sixth case has no recent travel history to areas with known mpox circulation and no established epidemiological link to previously identified cases. This suggests potential community transmission is occurring.
Health officials are intensifying contact tracing efforts to identify all potential contacts, offering medical follow-up, and recommending vaccination. Vaccination is being offered proactively to those at higher risk, including travelers, healthcare professionals, individuals with weakened immune systems, and those with multiple sexual partners.
What is Mpox and How Does it Spread?
Mpox is an infectious disease characterized primarily by a skin rash. This rash can appear on the face, around the genital area, and on the palms of the hands and soles of the feet. It may spread to other parts of the body and mucous membranes, often accompanied by itching. The rash can be preceded by or occur alongside fever, headache, muscle aches, and swollen lymph nodes.
Transmission occurs mainly through close contact, including:
- Direct contact with skin lesions of an infected person
- Contact with contaminated objects (clothing, bedding, dishes)
- Sexual contact, even with condom use
Transmission via respiratory droplets (saliva, sneezing, coughing) is considered less common and requires prolonged, close face-to-face contact without a mask.
The illness typically lasts between two and three weeks, and individuals are contagious from the onset of symptoms until all lesions have fully healed. A three-week period of isolation is recommended to prevent further spread.
The Role of Vaccination and Public Health Response
The ARS La Réunion launched a preventative vaccination campaign on February 9th, targeting at-risk populations. This proactive approach is crucial in controlling the spread of mpox, particularly given the ongoing circulation of the virus in the Indian Ocean region.
The availability of vaccines and the implementation of targeted vaccination strategies are key components of the public health response. Coordination between healthcare providers, infectious disease specialists, and vaccination centers is essential to ensure appropriate and timely vaccination.
Future Trends and Considerations
The emergence of cases with no clear travel history or epidemiological link suggests the virus may be establishing itself in new communities. Continued surveillance, robust contact tracing, and expanded vaccination efforts will be vital to mitigate further spread.
The Réserve sanitaire, a network of volunteer healthcare professionals managed by Santé publique France, plays a critical role in responding to public health emergencies like mpox. This reserve provides a readily available pool of skilled personnel to reinforce local healthcare systems when needed.
