A new strain of norovirus that was detected in Guangdong province now appears to be spreading across the globe. The stomach bug, known as GII.17, causes vomiting and diarrhea and could potentially sicken hundreds of millions of people worldwide, researchers say.
Concerns were high after “hundreds” of passengers were believed to have been infected with GII.17 on a Fred. Olsen & Co. cruise ship in Scandinavia last month.
Norovirus outbreaks are most prevalent in the winter, Bloomberg explains, but the number of infections witnessed over warmer months could determine how severe the outbreak will be when the mercury begins to drop.
