COVID-19 and Seasonal Influenza: No Room for Two
Objective
With the outbreak of COVID-19 in December 2019 fears were expressed for
a possible twindemic in the coming flu seasons. Fortunately, this was
not the case for the 2019-2020 and 2020-2021 flu seasons as flu showed
very low historical rates during these periods. The objective of our
study was to look at the existing flu data for the 2019-2021 period and
analyze possible reasons for the near absence of seasonal flu.
Methods
We performed retrospective surveillance regarding seasonal influenza
rates for the years 2019-2021, the years that the COVID-19 was present.
Epidemiological data concerning seasonal influenza for the years
2019-2021 were collected and analyzed
Results
Extremely low numbers of flu cases were reported in FluNet, FluView, and
TESSy influenza surveillance systems during the years 2019, 2020, and
2021 compared to previous years prior to COVID-19.
Conclusions
A twindemic outbreak during the 2019-2021 flu seasons did not occur
despite expressed concerns. The worldwide implementation of mitigation
measures for individuals and communities to control severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission, the
increased flu vaccination rate, the virus interference and the lower
rate of testing for flu are the main reasons for the marked decrease in
reported flu cases during 2019-2021 flu seasons
Ischemic heart disease and vascular risk factors are associated with accelerated brain aging
Ischemic heart disease (IHD) has been linked with poor brain outcomes. Brain age estimated from structural brain features and its deviation from actual age (brain-age delta in years, positive for accelerated brain aging) can express individual brain health in neurologically intact adults. Prevalent IHD is associated with accelerated brain aging and increased risk of dementia, that is not fully explained by microvascular injury. Besides shared vascular risk factors, additional disease-related mechanisms might contribute to abnormal aging. Brain-age delta may serve as an effective communication tool to illustrate the impact of modifiable risk factors and disease supporting preventative strategies
