Beijing: A preliminary investigation into viral pneumonia illnesses sickening dozens of people in and around China has identified the possible cause as a new type of coronavirus, state media said on Thursday.

Chinese health authorities did not immediately confirm the report from state broadcaster CCTV.

Coronaviruses are spread through coughing or sneezing or by touching an infected person. Some cause the common cold and others can lead to more severe respiratory diseases, such as SARS and MERS.

The novel coronavirus is different from those that have previously been identified, CCTV said.
