Weekly influenza overview

Week 42/2020 (12 October–18 October 2020) 

 

  • Influenza activity remained at interseasonal levels. 

 

  • None of 151 sentinel specimens tested for influenza viruses in week 42 were positive.

 

  • Of 7 262 non-sentinel specimens tested, 7 were positive (1 A unsubtyped and 6 type B viruses were not ascribed to a lineage).

 

  • There were no hospitalized laboratory-confirmed influenza cases for week 42/2020.  

 

  • The novel coronavirus disease 2019 (COVID-19) pandemic has affected healthcare presentations and testing capacities of countries and areas in the Region, which negatively impacted reporting of influenza epidemiologic and virologic data during the 2019-2020 season. It is not unusual for influenza activity to be low at this time of year but, if the COVID-19 pandemic continues influenza data we present will need to be interpreted with caution.
