The World Health Organization said on Sunday that while its analysis indicated that limited transmission of the virus is possible, there is no evidence yet that it can easily spread from one person to another. The group said it would continue to examine the issue.

That acknowledgment raises the possibility that the virus could be present in other markets in Wuhan, experts said, adding to fears that more people might be at risk.That acknowledgment raises the possibility that the virus could be present in other markets in Wuhan, experts said, adding to fears that more people might be at risk.
“If you cannot find the source and control the source of the virus, you cannot extinguish the fire,” said David Hui, the director of the Stanley Ho Center for Emerging Infectious Diseases at the Chinese University of Hong Kong.“If you cannot find the source and control the source of the virus, you cannot extinguish the fire,” said David Hui, the director of the Stanley Ho Center for Emerging Infectious Diseases at the Chinese University of Hong Kong.
Dr. Hui said the risk of widespread human-to-human transmission still appeared to be low, though he noted that the virus could mutate. Dr. Hui said the risk of widespread human-to-human transmission appeared to be low, though he noted that the virus could mutate.
Some experts have suggested that there are most likely far more cases of the illness than the authorities have disclosed. In previous incidents, including during the 2003 outbreak of severe acute respiratory syndrome, or SARS, the Chinese government has withheld critical information, drawing widespread criticism.

The new virus has brought back memories in China of the SARS outbreak, which was also caused by a coronavirus. That virus, which is believed to have jumped to humans from animals at markets, originated in China and was spread to other countries by travelers, infecting more than 8,000 people and killing more than 800.

“Until it becomes capable of human-to-human transmission, there’s not a major threat of a pandemic,” said Dr. Lipkin, the director of the Center for Infection and Immunity at the Columbia University Mailman School of Public Health. “We need to prepare for the possibility that this could be a larger outbreak and it could become a pandemic. But that doesn’t mean that it will.” “Until it becomes capable of human-to-human transmission, there’s not a major threat of a pandemic,” said Dr. Lipkin, the director of the Center for Infection and Immunity at the university’s Mailman School of Public Health.
