Monkeypox is a viral disease that primarily affects animals, including monkeys, rodents, and other mammals. However, it can also infect humans, causing symptoms similar to those of smallpox. The origins of monkeypox can be traced back to central and West Africa, where it was first identified in the 1950s. In this article, we will explore how monkeypox started and spread to various parts of the world.

The first known case of monkeypox was reported in 1958 when a pox-like disease affected captive monkeys in Copenhagen, Denmark. Initially, it was believed to be smallpox, but further investigation revealed that it was a new distinct disease. The disease was later named “monkeypox” after its initial outbreak in monkeys.

In the subsequent years, researchers identified several outbreaks of monkeypox in African countries, including Nigeria, the Democratic Republic of the Congo, and Cameroon. These outbreaks mainly affected rural areas, where individuals were in close contact with infected animals. People who hunted, prepared, or consumed bushmeat were found to be at higher risk of contracting the disease.

Monkeypox is caused by the Monkeypox virus (MPXV), which belongs to the Orthopoxvirus genus, the same family as the smallpox virus, Variola. Although smallpox was successfully eradicated through vaccination, monkeypox remains a public health concern, especially in Africa.

The virus is primarily transmitted to humans through direct contact with infected animals through broken skin, respiratory droplets, or consuming undercooked meat. Additionally, it can also spread through person-to-person contact, mainly through respiratory droplets or contact with bodily fluids. This person-to-person transmission has been observed in recent outbreaks outside of Africa, including the United States, Europe, and Asia.

The first recorded case of monkeypox outside Africa occurred in the United States in 2003 when a shipment of exotic rodents originating from Ghana was imported. The infected prairie dogs, intended as pets, transmitted the virus to humans. This outbreak, known as the Midwest outbreak, resulted in over 70 confirmed cases in the United States.

In 2019, the first case of monkeypox in Singapore was reported, linked to a Nigerian national who had traveled to the country. The case raised concerns about the potential global spread of the disease due to increased international travel and trade.

Preventing the spread of monkeypox relies on implementing strict surveillance measures, early detection, and rapid response to outbreaks. Vaccination, although not widely available, has shown promising results in preventing severe illness and reducing transmission.

Research efforts have been focused on developing a more effective vaccine against monkeypox. Several experimental vaccines have shown promising results in animal models, and clinical trials are underway. As the global health community continues to monitor and study the disease, improved surveillance systems, as well as public education on preventive measures, will be vital in controlling the spread of monkeypox.

In conclusion, monkeypox originated in Africa and primarily affects animals like monkeys and rodents. However, it can also infect humans, leading to a pox-like illness. The disease spreads through direct contact with infected animals or person-to-person transmission. With increased international travel and trade, monkeypox has been observed in various countries outside Africa, emphasizing the need for vigilant surveillance and preventive measures. Ongoing research and vaccination efforts are essential in controlling the disease and preventing potential outbreaks.
