Two people have been confirmed dead from a mystery virus in China, the officials said on Thursday.
The virus was also reported in Thailand, with dozens feared to have caught the deadly virus.
The latest fatality was a 69-year-old man from Wuhan in Central China. The city is believed to the epicenter of the outbreak.
Health officials say the virus is of the same family with the deadly Severe Acute Respiratory Syndrome (SARS) pathogen.
SARS killed 349 people in mainland China and 299 others in Hong Kong in 2002-2003.
According to a statement by Wuhan health officials, at least 41 people were hit by pneumonia linked to the mystery virus. Twelve patients have since been treated and released.
