A new virus from the same family as the deadly SARS pathogen could have been spread between family members in the Chinese city of Wuhan, local authorities said Wednesday.

The outbreak, which has killed one person, has caused alarm because of the link with SARS (Sudden Acute Respiratory Syndrome), which killed 349 people in mainland China and another 299 in Hong Kong in 2002-2003.

One of the 41 patients reported in the city could have been infected by her husband, Wuhan’s health commission said in a statement on Wednesday.
