US President Joe Biden said: “Monkeypox is a concern and we are looking into available vaccines and treatments.”

And the U.S. Food and Drug Administration has approved a new drug to treat monkeypox as cases of the rare virus have been found in 11 countries, including the U.S. and the U.K., where New York City-based SIGA Technologies announced that it has received the green light to receive an intravenous form of TPOXX, a smallpox medicine that is already available for oral administration.

And the drug has been added to doctors as a rare but potentially devastating virus as it continues to spread around the world after it was confirmed or suspected in dozens of cases in 11 countries in Europe and North America.

TPOXX is approved for use in Europe, the US and Canada, the three places where monkeypox is most active outside of Africa.
