Heart failure and lung failure do not cause COVID-19. But COVID-19 can cause heart failure and lung failure. There is also proof that health people and kids can die from COVID-19. If you look at the deaths, you can find that the fast decline in health all had something in common. And that is COVID-19.
You could have diabetes, Friend B could have high blood pressure, Friend A could have a heart condition. You guys live for it for 15 years with no major problems. Then one day your friends gets COVID-19 and suddenly have a quick onset of complications that only get worse and leads to death. You get COVID-19 two weeks later and you get a quick onset of health complications which quickly lead to death.
The only thing that you 2 had in common was COVID-19 and one of the common symptoms you three had was failing lung function. But none of you had lung disease. So yes while all of you had underlying illnesses. None of you had lung disease, but all 3 of you died from failing lung function caused by COVID-19
When you look at the deaths from COVID-19 you will see things like difficulty in breathing, failing lung function which is why people were being put on ventilators so that they could get assistance with breathing. What you don't see or hear about COVID-19 is that people are getting pace makers, heart transplants, stronger diabetes medicine.
It's clear here as they say that COVID-19 is affecting respiratory functions. But it's not the only thing that it destroys. It also affects other organ functions. In short it's a virus that does damage to more than one thing
There are also healthy people without underlying illnesses that die from COVID-19.

My guess is that younger people with no underlying illness are actually dying from a different strain of COVID-19. They aren't getting the same strain that causes minor symptoms. I've read that there are 2 Strains and that there are 8 Strains of COVID 19. I'm not sure which one is accurate at the moment. But based on some of the different symptoms that people are getting, it makes me think that there are more than one strain. There is also a case of a person getting re infected, but I don't know if that person was reinfected with the same strain or if it was a new Strain. My assumption is that the second infection is from a different Strain of COVID-19. The more people that get it the more likely it will mutate into something new to catch.
