Introduction
Monkeypox is a rare viral disease that is similar to human smallpox. It is caused by the Monkeypox virus, which is a member of the Orthopoxvirus family. The virus is believed to be transmitted to humans through direct contact with infected animals or through bites from infected rodents such as squirrels, monkeys, and rats. Monkeypox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was reported in 1970 in the Democratic Republic of Congo (DRC) during a period of intensified smallpox eradication efforts.
Symptoms of Monkeypox
The incubation period of Monkeypox is typically 5-21 days, and symptoms can range from mild to severe. The symptoms of Monkeypox include fever, headache, muscle aches, backache, swollen lymph nodes, chills, and exhaustion. A rash then typically appears, often beginning on the face then spreading to other parts of the body.
The rash may initially appear as raised bumps that are red and flat. These bumps quickly become fluid-filled and may be accompanied by a fever. Within a few days, the bumps will turn into pustules, which are raised bumps that contain pus. The pustules may be painful and itchy, and they may eventually break open and form a scab. The rash is often accompanied by itching and can last for several weeks.
The severity of Monkeypox varies, with severe cases being more common in Africa where the disease is endemic. Severe cases can cause a range of complications such as pneumonia, sepsis, and encephalitis. Encephalitis is a condition where the brain becomes inflamed and can cause seizures, confusion, and other neurological symptoms.
Causes of Monkeypox
Monkeypox is caused by the Monkeypox virus, which is a member of the Orthopoxvirus family. The virus is closely related to the human smallpox virus and is believed to have originated in animals, specifically rodents such as squirrels, monkeys, and rats. The virus is thought to be transmitted to humans through direct contact with infected animals or through bites from infected animals.
Humans can also become infected with the virus by coming into contact with infected body fluids such as blood, saliva, or respiratory secretions. The virus can also be spread through contact with contaminated objects such as bedding or clothing.
Monkeypox is most commonly found in central and West Africa, where it is endemic in animals. Outbreaks of the disease typically occur in rural areas where people have close contact with animals. The disease has been reported in several countries in Africa, including the Democratic Republic of Congo (DRC), Central African Republic, Cameroon, and Nigeria.
Diagnosis of Monkeypox
The diagnosis of Monkeypox is typically made based on the patient's symptoms and a physical exam. A healthcare provider will examine the patient's skin for the characteristic rash and may take a sample of the fluid from the lesions for testing.
Laboratory tests can be used to confirm the diagnosis of Monkeypox. These tests include PCR, which can detect the presence of the virus in the patient's blood or other body fluids, and serology, which can detect the presence of antibodies to the virus in the patient's blood.
Treatment of Monkeypox
Treatment for Monkeypox is mainly supportive and aims to relieve symptoms. There is no specific treatment or cure for the disease, and vaccination against smallpox does not provide immunity to Monkeypox. Treatment may include antiviral medications such as cidofovir or brincidofovir, which may help to reduce the severity of the disease.
