Human infection by orthopoxvirus is a rare but serious infection caused by a virus in the Orthopoxvirus family. It can cause a range of symptoms, including fever, rash, and swollen lymph nodes. In some cases, it can lead to more serious complications, such as encephalitis or even death. Vaccines are available to protect against some types of orthopoxvirus, but there is no specific treatment for the infection.

The symptoms of human infection by orthopoxvirus can vary depending on the specific virus, but generally include fever, headache, muscle aches, and fatigue. In more severe cases, a rash may develop, along with Lesions in the mouth, throat, and on the skin. In rare cases, orthopoxvirus can cause serious complications such as pneumonia, encephalitis, and even death.

The primary cause of human infection by orthopoxvirus is contact with infected animals, such as cows, sheep, goats, and camels. Human-to-human transmission is also possible, but it is rare. Other potential causes of infection include contact with contaminated objects, such as bedding or clothing, and inhalation of aerosolized virus particles.

1. Vaccination: Vaccination is the most effective way to prevent infection by orthopoxvirus. Vaccines are available for smallpox, cowpox, and monkeypox.

2. Antiviral medications: Antiviral medications, such as cidofovir, can be used to treat orthopoxvirus infections.

3. Supportive care: Supportive care, such as fluids and pain medications, can help to reduce symptoms and speed recovery.

4. Immunotherapy: Immunotherapy, such as interferon, can be used to boost the body’s immune response to the virus.

5. Surgery: In some cases, surgery may be necessary to remove infected tissue.
