COVID-19 Timeline

A timeline of COVID-19 and OT&P updates.

When managing epidemics of new infectious disease it is important to learn the lessons of the past, but also to recognise the specific variables and uncertainties of the present. Communicating risk in evolving epidemics involves recognising those uncertainties and being prepared to change advice on the basis of new and evolving evidence. Education, reliable information and effective communication are key factors in the management of epidemics of infectious disease.

As COVID-19 continues to spread in Hong Kong, and globally, information around this new disease evolves at a rapid pace. We have compiled a historical record of this evolving process for our patients. We have loaded all our previous communications such that they can be assessed in context.

Navigate through the months to see key disease milestones.
