Different viruses work differently and there\u0027s a common misunderstanding of how the immune system works. Here\u0027s what you need to know
Why are so many people sick right now?
There are also socioeconomic factors at play, said Dawn Bowdish, the Canada Research Chair in aging and immunity at McMaster University. The misunderstanding, basically, is the idea that kids went two years without getting sick and now their immune systems are weak and unable to cope with the viruses they haven’t been exposed to before.
However, the immune system’s memory is more developed in an adult or a vaccinated child — they can see a new virus and figure out how to respond. A kid who hasn’t been sick repeatedly, or hasn’t had his or her vaccines, is going to be less able to respond appropriately to a new virus. For kids, the first infection, Bowdish said, tends to be the worst, which helps explain the severity right now.
So viral transmission is still going to happen, kids will still get these diseases — it’s just not going to happen in one fell swoop that swamps the health-care system, Furness said.Article content
