What is Monkeypox?
Monkeypox is a viral disease caused by the monkeypox virus, a member of the Orthopoxvirus genus in the Poxviridae family1. This virus is closely related to the viruses that cause smallpox and cowpox1. Despite its name, the primary animal reservoirs for the monkeypox virus are not monkeys but small mammals like squirrels and rodents2.
First identified in 1958 in laboratory monkeys in Denmark, the first human case was recorded in 1970 in the Democratic Republic of the Congo1. Monkeypox is a zoonotic disease, meaning it can be transmitted from animals to humans and vice versa3. The disease presents with symptoms similar to smallpox but is generally less severe4.
Common symptoms of monkeypox include fever, headache, muscle aches, back pain, low energy, and swollen lymph nodes, followed by a rash that can last for 2-4 weeks1. The rash typically starts on the face and then spreads to other parts of the body, including the genitals3. The lesions go through several stages before eventually forming scabs and falling off5.
Understanding monkeypox is crucial for effective prevention and control, especially given its potential to cause significant outbreaks. By staying informed about the nature of the virus and its transmission, we can better protect ourselves and our communities.
Differences Between Monkeypox and Other Poxviruses

1. Causative Agent
- Monkeypox: Caused by the monkeypox virus (MPXV), which has two distinct clades: Clade I (Central African) and Clade II (West African)1.
- Smallpox: Caused by the variola virus, which has been eradicated globally since 19802.
- Cowpox: Caused by the cowpox virus, primarily affecting rodents and occasionally transmitted to humans3.
- Vaccinia: Used in the smallpox vaccine, the vaccinia virus is less pathogenic and is used for immunization purposes4.
2. Transmission
- Monkeypox: Transmitted through direct contact with infected animals or humans, and through respiratory droplets1.
- Smallpox: Spread primarily through respiratory droplets and direct contact with infected bodily fluids or contaminated objects2.
- Cowpox: Typically transmitted from animals (especially cats and rodents) to humans through direct contact3.
- Vaccinia: Not naturally occurring; transmission is primarily through vaccination4.
3. Symptoms
- Monkeypox: Symptoms include fever, headache, muscle aches, back pain, swollen lymph nodes, and a characteristic rash that progresses through several stages1.
- Smallpox: Characterized by high fever, fatigue, and a distinctive rash that develops into pustules and scabs2.
- Cowpox: Causes localized skin lesions, often on the hands or face, and mild systemic symptoms3.
- Vaccinia: Generally mild symptoms, including localized skin reactions at the site of vaccination4.
4. Severity and Mortality
- Monkeypox: Generally less severe than smallpox, with a mortality rate varying between 1-10% depending on the clade1.
- Smallpox: Highly severe with a historical mortality rate of about 30%2.
- Cowpox: Usually mild and self-limiting in humans3.
- Vaccinia: Rarely causes severe illness, primarily used for vaccination4.
5. Geographical Distribution
