On 9 February 2020, Shin Min Daily News quoted the findings of China and Hong Kong experts on aerosol transmission of novel coronavirus. 









Under the prominent news heading "Virus can be transmitted via aerosol, risk of infection without contact symptoms increases" , the newspaper quoted Hong Kong media as reporting that possible venues of aerosol transmission of novel coronavirus  at homes and social communities include taking a hot shower, massage shower, sauna, steam bath, using devices that generate a lot of water vapour including hotpot, humidifier and steam iron. 

Patients with respiratory symptoms are advised not to sit together with others that are without symptoms of the disease around hotpot.

In China, the route of transmission of novel coronavirus has been confirmed to include direct transmission, aerosol transmission and contact transmission.

According to the official explanation, direct transmission refers to droplet transmission, which refers to droplets inhaled from the patient's mouth and nose. Contact transmission is the contact of hands with items contaminated by the virus. Both of these require close contact.

The so-called "aerosol transmission", which is the official term, means that droplets are mixed in the air to form a suspended "aerosol", which causes infection after inhalation. Aerosols can flow with air and travel long distances, increasing the risk of contactless infection.

Prior to this, the spread of the virus through the air has long been widely suspected by the public but similar cases have repeatedly appeared in official reports. Earlier, some experts even reminded readers that in the home sewers, patients' viruses contained in the faeces of the patients may drift to other homes with the air flow in the sewers.

On a separate note, China expert Tong Chaohui has advised patients who have recovered from novel coronavirus and discharged from hospitals after two weeks should self-quarantine for another two weeks as there is a possibility of the patients contacting the virus again as respiratory symptoms may re-appear. Therefore the quarantine period can be as long as one month.
