COVID-19 Data and Surveillance
Data and surveillance play a vital role in managing a pandemic. The data that is collected can tell us how the pandemic is evolving, assess severity and risk and develop the necessary interventions to prevent further spread.
Since the onset of COVID-19, PHO has worked closely with the Ministry of Health and our local public health partners to collect, interpret and share COVID-19 data.
