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 March 11, 2020, the World Health Organization (WHO) classified COVID-19 as a pandemic. The number of cases are changing quickly and the provincial and federal governments are rapidly putting in place measures that are precautionary to minimize the risk of exposure and spread.
Since the outset, Public Health Ontario has been conducting laboratory testing and working with healthcare partners to expand testing capacity. We have also been working very closely with the Ministry of Health and local public health units to provide evidence and expertise to inform decisions and policy around surveillance, case and contact management, and infection control.
Please check the Ministry of Health website for additional information about the evolving situation, the provincial response and case numbers.
