The situation across Europe
According to the European Influenza Surveillance Network and the WHO, the intensity of the spread of influenza remains low within the European Union, as well as elsewhere in the world. The various hygiene and social distancing measures which have been implemented in order to prevent the spread of the SARS-CoV-2 virus have also played a role in preventing the spread of the influenza virus.
Influenza is caused by viruses from the Orthomyxoviridae family, and primarily by the influenza A, B, and C viruses. Influenza A viruses have the highest pandemic potential. The symptoms of the disease include rapidly increasing fever, headache, dry cough, and/or head cold, tiredness and weakness, and muscular and joint pain. Influenza may cause serious complications, such as pneumonia or an intensifying of chronic pulmonary or cardiovascular diseases.
Influenza is an acute viral disease which spreads in the form of outbreaks; either as an epidemic or as a pandemic. The disease mainly affects children, but most hospitalisation cases and deaths involve the elderly, as well as those individuals who suffer from chronic diseases.
