The World Health Organisation (WHO) has warned that it appears likely the novel coronavirus can be passed between people in close contact.
This comes after France confirmed a second case of a deadly new respiratory virus related to Sars, as they increased efforts to inform the public about how to avoid the illness and watch for its signs.
A hospital roommate of the 65-year-old man who initially contracted the virus tested positive for the illness. The second patient's condition has deteriorated, requiring treatment in intensive care, Health Minister Marisol Touraine said at a news conference. The minister added that the first patient is "in a stable but worrisome situation."
The virus is known to cause pneumonia and sometimes kidney failure.
