From the Background: "COVID-19 [coronavirus disease 2019] has spread rapidly around the world, affecting every community directly or indirectly. Stringent public health and social measures (PHSM) have been put in place by all countries to slow the spread of COVID-19. These include limitations on domestic and international travel; stay-at-home orders; closing of schools, shops, and religious centers; among other measures. As public health authorities consider the lifting some of these measures, it is critical that robust surveillance is in place or put in place to control the spread of COVID-19 and guide ongoing implementation of control measures. The aim of surveillance for COVID-19 is to limit the spread of disease, enable public health authorities to manage the risk of COVID-19, and thereby enable economic and social activity to resume to the extent possible. Surveillance is also necessary to monitor the longer-term trends of COVID-19 transmission and the changes in the virus. This guidance should be read in conjunction with WHO's [World Health Organization] guidance on preparedness, readiness and response actions."
