This week, an Australian man was diagnosed with monkeypox, a rare and deadly virus. The news has raised fears of an outbreak in the country, and officials are working to contain the virus. Monkeypox is closely related to smallpox, and can be fatal in up to 10 percent of cases. There is no known cure or prevention for the disease, which is believed to have originated in Africa. So far, there have been no confirmed cases of monkeypox in Australia, but health officials are urging people to take precautions against the virus. Anyone who suspects they may have contracted monkeypox should seek medical attention immediately.
