Coronavirus Disease 2019 (COVID-19)

In January 2020, a novel (new) coronavirus (COVID-19) was identified as the cause of an outbreak of pneumonia originating in Wuhan, China. The situation is rapidly evolving and Public Health Ontario, along with the Ministry of Health, is closely monitoring the outbreak, conducting surveillance and appropriate laboratory testing, and providing public health and infection control guidance.

Coronaviruses are a large family of viruses that originate in animals but are known to cause respiratory illness in humans, particularly during the fall and winter months. Other novel coronaviruses have included Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS-CoV).

Current Situation in Ontario

On January 30, 2020, the International Health Regulations Emergency committee of the World Health Organization declared the outbreak a “public health emergency of international concern”. However, the risk to Ontarians is still considered low. Additional information about the evolving situation can be found on the Ministry of Health website.

For case definitions please refer to the Ministry of Health COVID-19 Guidance.
