The current strain COVID-19 of the Coronavirus is getting 65 year old and older adults the most sick. You are likely to have much worse symptoms if you’re older, and people with pre-existing or chronic health conditions are at the most risk of having serious health complications or even death from this virus.
The influenza virus, better known as the flu affects this age group as well, however it also badly affects children under 2., which is something we are not seeing yet with this coronavirus. So far children are very resistant to COVID-19 and if they do get infected have very mild symptoms.
