Monkeypox is a rare viral disease that is similar to, but less severe than, smallpox. It was first identified in 1958 when outbreaks in monkeys kept for research purposes occurred. Since then, sporadic cases of monkeypox have been reported in humans, mainly in central and West African countries, including Nigeria, Cameroon, and Democratic Republic of the Congo. The recent outbreak of monkeypox in the United States in 2021 has raised concerns and highlighted the importance of understanding how this disease is contracted.

Monkeypox is primarily a zoonotic disease, meaning it is transmitted to humans from animals. The virus that causes monkeypox belongs to the family Poxviridae, which also includes variola virus, the causative agent of smallpox. The most common source of infection is through close contact with infected animals, mainly rodents and primates such as monkeys, squirrels, and rats. Direct contact with the bodily fluids or skin lesions of infected animals can lead to the transmission of the virus.

Another mode of transmission is human-to-human, although this is considered less common. Human-to-human transmission occurs through respiratory droplets generated by coughing or sneezing, close contact with infected secretions or lesions, or by touching contaminated objects or surfaces. However, compared to smallpox, the transmission rate of monkeypox from human to human is relatively lower. It requires prolonged and close contact for efficient transmission to occur.

Understanding the specific routes through which monkeypox is transmitted is crucial for preventing its spread. The risk of contracting monkeypox is higher in areas where the disease is endemic, mainly parts of Central and West Africa. Additionally, individuals who live in or travel to remote, rural areas where contact with wild animals is common are at higher risk. People engaged in hunting, trapping, and butchering animals for meat or those involved in the healthcare of infected patients are also at increased risk of exposure.

The incubation period of monkeypox is usually 7 to 17 days after exposure, during which an individual may not show any symptoms. The initial symptoms resemble those of flu, including fever, headache, muscle aches, and chills. As the disease progresses, a distinctive rash develops, initially as flat, red spots that later turn into fluid-filled blisters. These lesions are usually found on the face, palms of the hands, and soles of the feet. Additional symptoms may include swollen lymph nodes, fatigue, and a general feeling of discomfort.

Preventing monkeypox infection involves a combination of various measures. Vaccination against smallpox, which provides cross-immunity to monkeypox, can be effective in preventing the disease or reducing its severity. Avoiding contact with wild animals, especially sick or dead animals, is essential. Proper hand hygiene, including regular handwashing with soap and water or using alcohol-based hand sanitizers, is recommended. Wearing gloves and protective clothing when handling animals or their products can also help reduce the risk of infection.

In conclusion, monkeypox is a viral disease primarily transmitted from animals to humans. Direct contact with the bodily fluids or skin lesions of infected animals is the most common mode of transmission, although human-to-human transmission can also occur. Understanding the routes of transmission and implementing appropriate preventive measures are crucial in controlling the spread of this disease. Vaccination, avoiding contact with sick animals, practicing good hand hygiene, and using personal protective equipment are some of the key strategies in reducing the risk of monkeypox infection.
