A new strain of norovirus, which has made people sick in Japan and Western Europe, is now sweeping through the US, according to the Centers for Disease Control and Prevention.
CBS News reported the CDC said there have been over 140 outbreaks of the new strain since September in the US, which now accounts for over 60 percent of the global cases.
The stomach bug which appeared in Australia last March was dubbed the "GII 4 Sydney," according to the Washington Post.
Norovirus causes both vomiting and diarrhea and some deaths, but mostly among babies and the elderly.
Nursing homes and cruise ships are a common way it is transmitted, the Post wrote.
