Any virus if you're very unluckly or catch it at the wrong time can kill an otherwise healthy person. The flu kills thousands of otherwise relatively healthy people per year.
It's also not clear what "no underlying health conditions" really means. It doesn't necessarily mean the person is fit and healthy.
Generally the sevidence suggests the overall mortality rate for this is probably less than 1%, which suggests it's only a significant risk to someone who is already in a vulnerable state...but that does add up to a lot of people and you will also get the odd one off instance. This is why hospitals already struggle in the winter when other viruses such as influenza are more prominent.
Plus, the last time they said a young person with no underlying health conditions died of it here, it turned out they died of a heart attack. I'm not a medical professional but I'm fairly certain you can't die of a heart attack without there being an underlying health condition, and I'm even more certain you can't die of a heart attack directly because of corona virus.
This is true..to an extent. Some of the people I'm seeing written about 'no comorbidities' have actually been obese for example. Now, that isn't a comorbidity per se but certainly isn't healthy for you either and your organs will already be under more strain than it should be.
Some people actually are getting what's called myocarditis from Covid-19 and some studies suggest its the cause of death in 7% and a contributing factor in up to 1/3 of patients. You don't necessarily need to have a medical issue to get myocarditis but it obviously increases your chances of surviving it if you are otherwise healthy.
While Covid itself is horrible, I'm actually still more concerned by its effects on the general HC system. For multiple reasons. It fills up ITUs. That means other patients who should go to ITU aren't anymore. I had a quick peek at our (humungous) ITU yesterday. There were 2 non Covid ARDS patients out of 35. They're keeping beds open pretty much only for Covid.
We've cancelled all but emergency surgeries.
People are scared to come to hospital now. Which means we're seeing things that are quite unusual in this day (for example, heart wall rupture, which we so rarely see now in the PCI era for heart attacks). I am convinced that patients are dying at home because these emergency presentations haven't suddenly disappeared into thin air. Our admissions for STEMIs (the most severe heart attacks) and strokes have both gone down. We've stopped accepting neurosurgery patients. Which means patients we may be operating on and saving lives....we're now not.
And we're still not at the peak yet.
