The virus originates from primates and other wildlife and causes fever, body aches, chills and fatigue in most patients. People with severe cases can develop rashes and lesions on the face, hands and other parts of the body.
The smallpox-related disease, which first causes flu-like symptoms before progressing to a rash on the face and body, is common in parts of Central and West Africa. But this year, 1,880 infections have been reported in more than 30 countries where monkeypox is not common.
About 85% of cases are in Europe. There are no reports of deaths.
The World Health Organization has said that people with monkeypox can be contagious for up to four weeks and advised them to isolate themselves until they fully recover.
Lebanon is in the grip of the worst economic crisis in its history, and its medical sector is struggling with a shortage of medicines and medical equipment. The country is home to about 6 million people, including 1 million Syrian refugees.
