Coronavirus outbreak: WHO says the ‘hypothesis’ behind China’s new outbreak needs further testing

The origins of a new cluster of coronavirus infections in Beijing are uncertain, World Health Organization officials said on Monday, describing the claim that it might have been caused by imports or packaging of salmon as a “hypothesis.” Several districts of the Chinese capital put up security checkpoints, closed schools and ordered people to be tested for the coronavirus on Monday after an unexpected rise in cases linked to the biggest wholesale food market in Asia.
