FluCov: Influenza-COVID-19, understanding and communicating the impact of COVID-19 on influenza activity

Duration: Mar 2021 - Jul 2023


On 1 January 2020, the World Health Organisation (WHO) requested information on a reported cluster of atypical pneumonia cases in Wuhan from the Chinese authorities. On 1 March 2020, WHO made the assessment that SARS-CoV-2 could be characterized as a pandemic. The emergence of this new virus has had a major impact on the global circulation of respiratory viruses, including influenza and RSV.

Participating countries

A number of 22 contextual and geographical representative countries have been selected:

  • Africa (2): Egypt, South Africa
  • America (4): Brazil, Canada, Mexico, USA
  • Europe (8): France, Germany, Israel, Italy, Netherlands, Poland, Spain, United Kingdom
  • South Asia (4): India, Philippines, Thailand, Vietnam
  • Pacific (4): Australia, China, Japan, South Korea

Doel Aim

FluCov aims are threefold:

  1. to document and communicate about the impact of the SARS-CoV-2 pandemic on influenza activity
  2. to document and communicate about measures to prevent and control influenza in the coming years (e.g. by vaccination)
  3. to model future epidemic scenarios, with a focus on influenza activity

Producten en dienstenProject design

The research project consists of four components:

  1. establish a procedure to access and publish routine influenza (FluNet data) and SARS-CoV-2 surveillance data
  2. implement a testing and laboratory practices survey of National Influenza Centres to assess how SARS-CoV-2 has impacted influenza surveillance capacity
  3. collect influenza vaccination coverage rates in the selected countries (by risk group)
  4. In collaboration with colleagues at EHESP, develop and apply a modelling strategy to produce scenarios on the possible resurgence of influenza activity in the coming years


We share our research and findings by providing access to the FluCov Bulletins, posters, and survey results:

  1. a dashboard which allows visitors to query the influenza and Sars-Cov-2 data themselves
  2. the FluCov Bulletins: regular publications of the epidemiological assessment on the impact of SARS-CoV-2 on influenza activity
  3. scientific publications:
    • an abstract regarding the epidemiological impact of the SARS-CoV-2 pandemic on influenza activity, which was submitted to ESCAIDE (European Scientific Conference on Applied Infectious Disease Epidemiology) in November 2021
    • two abstracts which were submitted to Options XI: 1) the NIC survey results and 2) the modelling study/strategy (by EHESP)

Result 1: FluCov Dashboard, the impact of SARS-CoV-2 on influenza

The emergence of SARS-CoV-2 in 2019 had a major impact on the global circulation of respiratory viruses, including influenza (see In order to understand the impact of SARS-CoV-2 on influenza activity worldwide, the FluCov Dashboard offers users a clear view of the current and past circulation of both viruses (since 2019), in a wide range of countries all over the world. Real-time weekly surveillance weekly data are downloaded and presented in the Dashboard.
