Monkeypox overview
Monkeypox is a rare viral disease that occurs primarily in remote parts of Central and West Africa, near tropical rainforests. The virus is similar to human smallpox but less severe. The disease is transmitted to humans from animals, usually rodents or primates, through contact with the animal’s blood, bodily fluids, or bites or scratches.
It can also be transmitted from person to person through respiratory droplets or contact with bodily fluids. Symptoms of monkeypox include fever, headache, muscle aches, and a rash that develops into pustules. There is no specific treatment for monkeypox, but the smallpox vaccine has been shown to be effective in preventing the disease.
What is the monkeypox virus?
Monkeypox virus is a member of the Orthopoxvirus genus, which also includes the variola virus (the cause of smallpox), vaccinia virus (used in the smallpox vaccine), and cowpox virus. It is a double-stranded DNA virus that is similar in structure to other poxviruses. Monkeypox virus is known to infect a variety of animals, including rodents, primates, and even some species of birds. In humans, it causes a disease called monkeypox, which is similar to smallpox but is less severe.
What are the causes of monkeypox?
Monkeypox is caused by a virus called monkeypox virus, which belongs to the same family of viruses as the smallpox virus. The virus is primarily transmitted to humans through contact with infected animals, particularly rodents and primates such as monkeys, chimpanzees, and squirrels. The virus can also be transmitted from human to human through close contact with infected bodily fluids, such as saliva, blood, and skin lesions.
In some cases, the virus can also be transmitted through respiratory droplets, such as when an infected person coughs or sneezes. This type of transmission is rare and generally occurs only in outbreaks where there are many infected people in close quarters.
It is important to note that while monkeypox is similar to smallpox, it is generally a milder disease with a lower mortality rate. However, in rare cases, severe illness and death can occur, particularly in people with weakened immune systems.
What is the pathogenesis of monkeypox?
Monkeypox is a rare viral disease that is caused by the monkeypox virus, which belongs to the family Poxviridae. The exact pathogenesis of monkeypox is not completely understood, but it is believed to involve several steps.
First, the virus enters the body through contact with infected animals or contaminated materials. The virus then begins to replicate within the host’s cells, particularly in the skin, lymph nodes, and respiratory tract.
As the virus replicates, it causes damage to the host’s cells and triggers an inflammatory response, leading to the formation of characteristic skin lesions and other symptoms. The virus can also spread to other organs, including the liver, spleen, and lungs, causing further damage and inflammation.
The severity of monkeypox can vary widely, ranging from a mild illness with few symptoms to severe and potentially fatal disease. The severity of the disease is thought to be influenced by factors such as the virulence of the virus strain, the immune status of the host, and the age and overall health of the host.
Treatment for monkeypox is primarily supportive, and there is currently no specific antiviral therapy available. Vaccination against smallpox, a related virus, has been shown to provide some protection against monkeypox.
How prevalent is monkeypox?
Monkeypox is a rare disease and is not very prevalent. It is primarily found in central and West African countries, including Cameroon, the Central African Republic, the Democratic Republic of the Congo, Gabon, Nigeria, and the Republic of the Congo. However, sporadic cases have also been reported outside of Africa, including in the United States, the United Kingdom, and Israel, mostly among travelers who had been to areas where monkeypox occurs. The overall number of cases reported each year is relatively low.
What are the Monkeypox Symptoms?
The symptoms of monkeypox can vary widely in severity, ranging from a mild illness with few symptoms to severe and potentially fatal disease. The incubation period, or the time from infection to onset of symptoms, is usually 7 to 14 days.
Some common symptoms of monkeypox include:
- Fever
- Headache
- Muscle aches
- Fatigue
- Backache
- Swollen lymph nodes
- Chills
- Sweating
- Rash that begins on the face and then spreads to other parts of the body
- Lesions that progress to pustules, and then scab over and fall off

In severe cases, monkeypox can also cause:
- Encephalitis (inflammation of the brain)
- Pneumonia (infection of the lungs)
- Sepsis (infection of the bloodstream)
- Bleeding disorders
The severity of the disease is thought to be influenced by factors such as the virulence of the virus strain, the immune status of the host, and the age and overall health of the host. Treatment for monkeypox is primarily supportive, and there is currently no specific antiviral therapy available.
Vaccination of monkeypox
Currently, there is no specific vaccine for monkeypox available to the general public. However, a smallpox vaccine is known to provide protection against monkeypox as well. The smallpox vaccine is made from a virus called vaccinia, which belongs to the same family as the monkeypox virus.
In countries where monkeypox is endemic or outbreaks occur, vaccination with the smallpox vaccine is recommended for people who are at high risk of exposure, such as healthcare workers, veterinarians, and laboratory personnel. The vaccine is also recommended for people traveling to endemic areas or who are in close contact with infected individuals.
It is important to note that the smallpox vaccine can cause serious side effects, and it is not recommended for people with certain medical conditions, such as weakened immune systems. Therefore, it is crucial to consult a healthcare professional before getting vaccinated with the smallpox vaccine.
precaution for monkeypox ?
The best way to prevent monkeypox is to avoid contact with infected animals and materials. If you live in or travel to areas where monkeypox is known to occur, you should take the following precautions:
- Avoid contact with animals that could carry the virus, such as rodents and primates.
- Wear gloves and other protective clothing when handling potentially infected animals or materials.
- Wash your hands frequently with soap and water, especially after handling animals or materials that could be contaminated with the virus.
- Avoid touching your face, particularly your eyes, nose, and mouth, with unwashed hands.
- Cover any cuts or wounds with a bandage before handling potentially infected animals or materials.
- Cook all meat thoroughly before eating it.
- Practice good hygiene, such as regular hand washing and avoiding sharing personal items like towels and clothing.
If you think you may have been exposed to monkeypox, you should seek medical attention immediately. Early diagnosis and treatment can help improve outcomes and reduce the risk of complications.
