I'm sorry Raja
So Poland is coming out of the third wave and a lot of articles were mentioning similar stuff as the India article “It’s affecting young adults. It’s affecting families. It’s a new thing altogether. Two-month-old babies are getting infected.”
My take on that is
1) the British variant (which is common in Poland) does actually affect younger people and children more - it's been said it's more contagious and more symptomatic in younger people
2) many more people are getting infected than during the second wave (we didn't really have a first wave to speak of) so you obviously see more younger people affected
3) people (and especially younger people) are tired of restrictions and aren't as compliant, so they get sick more.
4) older people are vaccinated to a much higher degree so fewer get sick, which means that you mostly see younger people getting sick
it's also been reported that the actual age of people who are dying or end up in ICU hasn't really changed. It still kills older people.
I would also agree that some doctors falling ill is not that mysterious for reasons Pod already mentioned. Doctors are exposed to much higher viral loads than regular people, and I bet their PPE is not always that meticulous in a crisis situation because there's no time for making sure it is.
