Definition

Global Surveillance for human infection with coronavirus disease (COVID-19).

The objectives of this global surveillance are:

  1. to monitor trends of the disease where human to human transmission occurs;
  2. rapidly detect new cases in countries where the virus is not circulating;
  3. provide epidemiological information to conduct risk assessments at the national, regional and global level; and
  4. provide epidemiological information to guide preparedness and response measure
