French health authorities have announced the discovery of 51 cases of monkeypox amid an increase in the number of confirmed cases worldwide.

Paris reported the first cases in May, bringing the total number of confirmed cases to 33 on Wednesday.

On Friday, the US Centers for Disease Control and Prevention said they are aware of more than 700 cases of monkeypox worldwide, including 21 cases in the United States.

And the French Public Health Authority indicated that all the injuries were recorded in men between the ages of 22 and 63, and that only one person was admitted to the hospital and was later discharged from it.

According to the World Health Organization, monkeypox is a rare zoonotic viral disease (the virus is transmitted from animals to humans), and the symptoms of human infection are similar to those experienced by humans with smallpox, but less severe.

In some patients, lymph nodes swell even before the rash appears, which distinguishes monkeypox from other similar diseases.

There is currently no treatment or vaccine available to combat this virus, but smallpox vaccination has proven to be highly effective in preventing monkeypox.

Monkeypox was first identified in the Democratic Republic of the Congo in 1970, and since then most cases have been reported in the rural rainforests of the Congo Basin and West Africa.
