Sollte durch die ganzen Corona-Toten jetzt nicht eigentlich eine niedrigere Sterblichkeit herrschen, da vornehmlich alte Menschen gestorben sind?
Es hat sich weltweit ein zusätzliches, den Menschen infizierendes Virus etabliert. Mit dem sich früher oder später jeder infiziert und dessen Langzeitfolgen sich erst nach und nach zeigen.
So sind z.B. laut dem Bericht der SwissRe Herz-Kreislauf Tote seit 2020 unerwartet stark gestiegen und es wird angenommen dass Covid-19 immer noch treibende Kraft der Übersterblichkeit ist:
The UK and US data shows a large, unexplained jump in deaths attributed
to cardiovascular disease (CVD) since 2020. Some countries also reported excess
mortality over a pre-pandemic baseline for other major causes of death, such as cancer.
Based on current medical trends and expected advancements, we conclude
that COVID-19 is still driving excess mortality both directly and indirectly.Als Gründe dafür werden die zusätzlichen Toten durch Covid-19 bei Atemwegserkrankungen und bei Herz-Kreislauf-Erkrankungen aufgeführt:
1. Respiratory deaths likely to stay the key contributor to global excess mortality
While testing has certainly dropped since the start of the pandemic, the vast
majority of respiratory deaths are attributed to COVID-19.
Influenza continues to drive seasonal, winter respiratory deaths. While flu
deaths were greatly reduced when societal restrictions were in place for
COVID-19, these have now returned.
Flu vaccination rates remain high, yet social changes such as mask wearing have
mostly abated, but still remain common in countries where masks were more
frequently used pre-COVID-19 (for example, in East Asia). However, the risk
factors for COVID-19 and flu deaths often overlap.
2. Post-COVID-19 long-term impacts on respiratory and cardiovascular disease
...
A US Department of Veterans Affairs’ study on 150 000 COVID-19 patients
highlighted increased CVD risks. Symptomatic patients, 30 days post-infection,
had higher CVD events and mortality rates across all demographic groups and
regardless of pre-existing conditions.
Even non-hospitalised patients had higher CVD rates than controls, with increasing
infection severity likelihood of a cardiac event. 14
Vorteile haben die Länder die die starke Ausbreitung der ersten SARS-Cov-2 Varianten durch Gegenmaßnahmen verhindert haben, aber zukünftig werden Impfungen den Effekt auf die Übersterblichkeit gering halten:
Long-term cardiovascular complications of COVID-19 need further
investigation, but severe post-COVID-19 impacts mainly come from early variants.
Healthy, highly immune populations may experience fewer long-term effects.
Duration: post-COVID effects have so far mirrored COVID-19 infection severity levels.
We expect the impact of these to decrease if variants of COVID-19 remain mild and
are well managed with vaccination.
Norway, Denmark and Australia reported no or negative excess mortality
until 2022, likely as a consequence of more stringent lockdowns, a
vaccinated population and other societal actions.
