BEIJING (AP) — Chinese state media says the city of Wuhan is shutting down outbound flights and trains as new virus spreads more widely.

A national health official says 440 cases are confirmed in China.

China's Hubei province announced Wednesday that the death toll from the new virus has risen to 17. All of the deaths have been in Hubei province, where the first cases were reported last month.

The illness comes from a new coronavirus that experts say may be spread through the respiratory tract and may be mutating.

The outbreak initially was connected to a seafood market in the central city of Wuhan, but human-to-human transmission could make the virus spread more quickly and widely.
