Mpox, previously known as monkeypox, is a viral infection that affects humans and shares similarities with smallpox, albeit being less fatal. While the majority of cases are reported in Africa, there have been outbreaks in other countries due to international travel and the trade of exotic pets. The discovery of Mpox or monkeypox dates back to 1958 when a group of monkeys, imported from Singapore, fell ill at a research facility in Denmark. However, it wasn’t until 1970 that the first confirmed human case emerged, involving a child from the Democratic Republic of Congo who was initially suspected of having smallpox.
Endemic to Africa
Monkeypox is a viral disease that is endemic to Africa, with the majority of cases being reported in the Democratic Republic of the Congo. However, since 2016, there has been a noticeable increase in cases across other African countries. It is important to note that the actual number of cases is likely to be much higher than reported, as most incidents occur in rural areas where proper diagnosis and reporting are limited.
There are several complex factors contributing to the rise in monkeypox cases, but one significant reason is the eradication of smallpox. The elimination of smallpox as a natural competitor has potentially allowed the monkeypox virus to thrive and spread more easily.
Cases of Monkeypox Outside of Africa
Monkeypox, a disease typically endemic to Africa, has also been reported in other parts of the world on sporadic occasions. In 2003, an outbreak occurred in the American Midwest when rats imported from Ghana infected prairie dogs, leading to over 50 human cases. Additionally, cases of individuals contracting the virus after traveling to Africa were reported in 2018, 2019, and 2021.
According to the World Health Organization, there has been a significant increase in monkeypox cases in countries where the disease is not endemic since May 2022. Surprisingly, some of the affected individuals had a confirmed travel history, but their travel was limited to North American and European countries. This marks the first time that widespread clusters of monkeypox cases have been observed outside of Africa.
