Dlugotrwale efekty uszkodzenia miesnia sercowego po nawet lekkim przebiegu choroby, u osob 40-50 lat (czyli rodzicow dzieci szkolnych) bez chorob wspolistniejacych. . Ku przestrodze tych, ktorzy tak ochoczo przyklaskuja otworzeniu szkol pelnoetatowo z wietrzeniem sal i myciem rak jako zabezpieczeniem przed infekcja I narazaniem nauczycieli I personelu I wszystkich naokolo w komunikacji miejskiej I srodowisku.

Jeszcze duzo nie wiemy o biologii wirusa.....

There is new evidence that COVID-19 can have lasting effects on heart health, which may go undetected in patients who assume they have recovered from the infection.
Two studies from Germany, published Tuesday in the journal JAMA Cardiology, show how the virus can linger in the heart for months, even without producing symptoms.
Full coverage of the coronavirus outbreak
The first study included 100 coronavirus patients from the University Hospital Frankfurt COVID-19 Registry. Most were otherwise healthy adults in their 40s and 50s.
All had MRIs of their heart two to three months after they were diagnosed with the virus, when many seemed to have fully recovered. Those images were compared to people who'd never had COVID-19.
‘Broken heart syndrome’ spikes during COVID-19: What is it?

Out of those 100 COVID-19 patients, 78 still had visual signs that the virus had an impact on the heart. Sixty of those patients had signs of ongoing inflammation of the heart muscle.
"That's really compelling," Dr. Clyde Yancy, chief of cardiology in the department of medicine at Northwestern Medicine in Chicago, told NBC News. "It indicates that months after exposure to COVID-19, we can still detect evidence of a heart that's not completely normal."
The problem may not lead to physical symptoms, but could indicate risk for further heart damage.
"Once the heart muscle has been injured, there is the potential for progressive injury," Yancy wrote in an editorial accompanying the studies.
Because the virus is so new, it's not yet known what long-term cardiovascular risks come with COVID-19.
No pre-existing conditions would have explained the damage, the study authors said, and only a third had been hospitalized with COVID-19. The rest were able to remain at home throughout the course of their illness.
"Our findings may provide an indication of potentially considerable burden of inflammatory disease in large and growing parts of the population," the study authors wrote.
One-third of COVID patients who aren't hospitalized have long-term symptoms
The second study included 39 autopsies of people who'd died of COVID-19. Those patients tended to be older, in their 80s. Researchers found evidence of the virus in the heart tissue in 24 of the 39 patients.
What's more, five of those patients had signs the virus was actually replicating in the heart tissue.
