Remarks

  1. ↑ Positive rate = number of positive samples / number of samples sent. The proportion of the total positive samples can deviate from the sum of the positive samples of the individual viruses if multiple infections (e.g. with influenza and rhinoviruses) have been detected.
  2. ↑ Since week 8, 2020, sentinel samples have also been tested for SARS-CoV-2. For technical reasons, these values ​​cannot be shown here. An alternative graphic can be found in COVID-19 pandemic in Germany # Comparison with influenza (flu) .
