Each year, a flu epidemic occurs. Three or four times a century , a pandemic takes place caused by a new influenza virus. The type of the virus that circulates and the vulnerability of the population determine the severity of the epidemic or pandemic. That is why a flu surveillance should be organised every year. In Belgium, the Scientific Institute of Public Health (WIV-ISP) manages the existing surveillance systems, financed and controlled by the Federation Wallonia-Brussel, the Flemish Agency for Care and Health of the Flemish Community, and the Brussels Common Community Commission. The objectives of the flu surveillance are:
- To describe the epidemic over time (i.e. to design the epidemic curve) and per age groups;
- To identify the circulating viruses and their main characteristics;
- To evaluate the severity and impact of the epidemic in the population.
