Coronavirus disease (COVID-19) in China

Updated: March 04, 2020


Original publication: January 7, 2020

Current situation

An outbreak of respiratory illness, first identified in Wuhan, Hubei Province, continues to spread within China. The outbreak now affects all provinces in the country. It is being caused by a novel (new) coronavirus. Disease caused by this novel coronavirus has been given the name COVID-19. Confirmed cases are being reported in countries outside of China, including Canada, and more are expected. Confirmed cases have also been reported amongst international travellers on cruise ships, resulting in the quarantine of passengers on board the vessel.

Chinese health authorities and the World Health Organization (WHO) have confirmed human-to-human transmission is occurring. Available information indicates that older people and people with a weakened immune system or underlying medical condition are considered at higher risk of severe disease. Travellers who get ill while travelling in China may have limited access to timely and appropriate health care. For these reasons, it is recommended that travellers consider avoiding non-essential travel to China. 

Chinese officials in some cities are implementing exceptional measures to reduce further spread of the virus. Given these safety and security risks, the Government of Canada is continuing to recommend that Canadians avoid non-essential travel to China and avoid all travel to Hubei province.

On January 30, 2020 the WHO declared the outbreak to be a Public Health Emergency of International Concern (PHEIC)

About the COVID-19 outbreak

While it is believed that the virus originated from an animal, the widespread outbreak is due to human-to-human transmission.

As with other respiratory illnesses, COVID-19 can cause mild symptoms including cough and fever. It can also be more severe for some people and lead to pneumonia or breathing difficulties.

A number of countries and territories have begun screening travellers arriving from China. Travellers returning to Canada from areas affected by the COVID-19 outbreak, particularly from Hubei Province, should be attentive to messages and instructions being provided at Canadian airports. They will be asked about their travel history and may be asked further questions about their health.

The Public Health Agency of Canada is actively monitoring the situation and working with the WHO and other international partners to gather additional information. The situation is evolving rapidly. Please verify travel health recommendations regularly as they may change over the course of your travel as new information becomes available.

About coronaviruses

Coronaviruses are a large family of viruses that cause respiratory illnesses. Some coronaviruses can cause no or mild illness, like the common cold, but other coronaviruses can cause severe illness, like Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and the Middle East Respiratory Syndrome Coronavirus (MERS-CoV).

Some human coronaviruses spread easily between people, while others do not.

There are no specific treatments for illnesses caused by human coronaviruses. Most people with common human coronavirus illnesses will recover on their own.
