Monkeypox Resurfaces in Yucatán After Four Months

Yucatán Returns to High Incidence List After Four Months Without Cases

After four months without records, Mpox infection (previously called monkeypox) has reappeared in Yucatán, placing it among the 15 states in the country with the highest incidence, according to information from the federal Ministry of Health.

So far this year, this is the second epidemic outbreak in Yucatecan territory, accumulating four confirmed cases. The reappearance occurred during epidemiological week 48, corresponding to November 23-29, a period in which seven new infections were identified in the country: three in Mexico City, two in the State of Mexico, one in Puebla, and one in Yucatán.

At the moment, Campeche does not record active or accumulated cases in 2025, so it remains within the group of entities free of Mpox during the year.

Quintana Roo Ranks Sixth Nationally with 19 Confirmed Cases

Quintana Roo, for its part, ranks sixth nationally, with 19 confirmed cases, equivalent to 2.51% of the total. It is the state with the highest incidence. Health authorities urge the population to reinforce prevention measures, especially among people with multiple sexual partners, the group with the highest number of infections.

The recommendations include:

• Avoiding contact with people who present skin lesions
• Not sharing clothing or personal objects
• Washing hands frequently
• Using condoms as a complementary measure
• Seeking medical attention if fever, swollen lymph nodes, or rashes appear

Nationally, Mexico has recorded 758 Mpox cases in 2025, representing an increase of 570.8% compared to the same period last year, when only 113 were counted.

The highest concentration of cases remains in Mexico City, with 432 infections (57.78%), followed by Jalisco with 82 (10.82%), and Nuevo León with 57 (7.52%). In contrast, the disease is absent in Campeche, Colima, Guerrero, Sonora, and Tabasco.

In Yucatán, the four records correspond to males. Epidemiological surveillance remains active throughout the peninsular region.
