Monkeypox in Madagascar: 16 confirmed cases of Mpox in Mahajanga, according to authorities

Mis à jour le 21 May 2026

A worrying resurgence of the monkeypox virus, also known as Mpox, is currently affecting Madagascar, with a notable intensification in Mahajanga. At the heart of this outbreak, 16 confirmed cases have been identified by health authorities in this strategic region of the Indian Ocean, sending shockwaves through the public health community. The situation, occurring within a global context of heightened vigilance against this ancient but formidable virus, raises numerous questions regarding the management, prevention, and understanding of this disease, which has demonstrated renewed resilience in various geographical areas in recent years. As the threat becomes more pronounced in Madagascar, the scientific community—alerted by this resurgence—must mobilize all its resources to curb this emerging epidemic, while simultaneously fostering a multidimensional awareness of the real risks of contamination.

Epidemiological context: a resurgence of monkeypox in Madagascar Since the beginning of 2026, Madagascar has seen a significant increase in Mpox cases, with a notable concentration in Mahajanga. The official confirmation of 16 cases by the Ministry of Public Health illustrates an alarming situation requiring an immediate and coordinated response. The first symptoms, such as fever, headaches, lymphadenopathy, and skin rashes, often appear in children under five or pregnant women, further complicating treatment. The Mahajanga region, a key hub for logistics and economic exchange, is seeing its health stability jeopardized by this new wave. Factors contributing to this resurgence in a tropical environment

Several factors contribute to the resurgence of the disease in Madagascar. Population density in certain neighborhoods, combined with increased mobility, facilitates transmission through direct contact with lesions or via contaminated objects. Proximity to wild animals, particularly monkeys, constitutes an additional vector of spread. The weakness of the epidemiological surveillance system, exacerbated by a lack of resources for hygiene and public awareness campaigns, partly explains this resurgence. The circulation of the virus in an environment where awareness of the disease remains insufficient calls for increased vigilance, especially in a context of ever-increasing migration, requiring a collective response. Transmission through close contact is further reinforced by the fact that some detected cases involve children and pregnant women, particularly vulnerable groups.

Measures taken by health authorities to contain the spread of Mpox in Madagascar

Faced with this emerging epidemic, the Ministry of Public Health A Public Health Emergency Operations Center was immediately mobilized. Its objective: to coordinate and monitor the evolving situation while limiting the spread of infection. Informed by experts, the strategy relies primarily on the implementation of strict preventative measures. These include not sharing personal belongings, covering lesions with clothing or bandages, wearing a mask in public places, and maintaining rigorous hand hygiene with disinfectant solutions. The implementation of information and awareness campaigns is also crucial in this context. Local collaboration with the Pasteur Institute, an expert in virology, ensures continuous monitoring, notably through regular laboratory testing and epidemiological tracking.

The Role of Local Communities in the Fight Against Pox

To curb this contagion, the authorities also emphasize the essential role of communities on the front lines. Awareness campaigns, particularly in working-class neighborhoods, aim to strengthen understanding of transmission methods and preventative measures. Training healthcare workers, increasing the availability of medical equipment, and providing free masks are all concrete actions to limit the spread. Collaboration with community leaders allows for constructive dialogue and reassures the population about the health risks involved. Collective mobilization appears to be one of the key factors in quickly controlling the situation, thus preventing a wider health crisis. How is the Mpox virus transmitted and what precautions should be taken?

The virus responsible for monkeypox, or Mpox, is primarily transmitted through close contact. Transmission can occur through direct contact with lesions, bodily fluids, or objects contaminated by an infected person. While rare, transmission via respiratory droplets is also possible during prolonged close contact. To limit these risks, it is essential to strictly follow a few simple but effective rules:

• 🧴 Do not share personal belongings, especially clothing, towels, or medical supplies.
• 🧥 Cover lesions with clothing or bandages to prevent further spread.

😷 Wear a mask when in close proximity to someone with symptoms.

🧼 Wash your hands regularly with soap and water or use an alcohol-based hand sanitizer.

💉 Follow quarantine guidelines if you suspect or confirm a case.

Specific vulnerabilities in the Malagasy context

This disease finds fertile ground in certain segments of the local population where a lack of healthcare infrastructure and low awareness exacerbate vulnerability. Families living in precarious housing or in marginalized rural areas face difficulties accessing timely care. The stigma often associated with the disease can further isolate confirmed cases, delaying treatment and increasing the risk of transmission. Prevention must therefore include an educational approach, so that the population understands that Mpox can affect anyone, regardless of age or socioeconomic status.

Epidemiological surveillance and prevention: a challenge for Madagascar in 2026

Effective management of the Mpox threat requires continuous surveillance and multifaceted collaboration between health, scientific, and community institutions. Regular testing and close monitoring of case progression allow for the anticipation of potential mutations or more severe forms of the disease. Vaccination, still advocated in some countries for at-risk groups, remains an option under consideration for Madagascar, but requires political and logistical mobilization. Furthermore, increased public awareness remains a cornerstone for preventing stigmatization and encouraging adherence to preventive measures. International collaboration, particularly with the WHO, must be strengthened to build a truly united front against this worrying resurgence of the virus in the region.

1. The challenges and stakes for better management of this epidemic in Madagascar Strategically, Madagascar must strengthen its surveillance and diagnostic capacities, while ensuring the effective flow of information. Awareness campaigns must target both healthcare professionals and the general public, emphasizing the importance of rapid detection and the need for immediate isolation. The difficulty also lies in the management of resources, which are often limited, sometimes preventing an effective response. Political will must be combined with international commitment for optimal care. Implementing a comprehensive plan, integrating prevention, case management, and follow-up, will prevent the situation from worsening further, without excluding the possibility of resorting to vaccination in cases of urgent need.
2. The socio-economic impacts of the recent resurgence of monkeypox.
3. Beyond the health crisis, the resurgence of the Mpox virus in Madagascar poses significant socio-economic challenges. Fear of infection, coupled with a cluster of cases in Mahajanga, breeds suspicion and sometimes stigmatization of victims or affected areas. The fear of local economic activity slowing down or being suspended, as well as the disruption to tourism, exacerbates an already fragile situation in this region. Communication must play a crucial role in reassuring the population and preventing harmful mass panic. Implementing support measures, particularly for vulnerable families, will help mitigate the impact of this health crisis and maintain social stability, while pursuing a sustainable prevention strategy.

What are the first symptoms of monkeypox?

Monkeypox typically manifests as fever, muscle pain, swollen lymph nodes, and skin rashes, often on the face, hands, or arms, which can rapidly develop into pustular lesions requiring immediate medical attention.

How is the Mpox virus transmitted?

The virus is primarily transmitted through close contact with an infected person or their lesions, but also via contaminated objects, such as clothing or medical equipment. Standard precautions, such as wearing masks and rigorous hygiene, remain essential to prevent infection. What preventive measures do you recommend in Madagascar?
