Do you normally have a flu jab?
How old are you? (Age is a huge factor).
Everyone is in at risk group to some extent, even the young. It's up to you (and your medical team and to some extent the government) as to how high that risk is.
Oh, and apparently smoking puts the risk of catching the virus up a lot, so there's another factor to consider.
I think if you have a health condition you should take all precautions- actually even if you don't you should take precautions. But if you have any health conditions or live with someone who does you should take precautions- if you end up in hospital your stay there may be longer than someone without those conditions.
Everyone should be careful. This is something that has already effected the world in an unprecedented way.
Take care everyone and stay well. We are so fortunate to have this site and others to stay in touch with each other- we may be physically isolated but we can reach out to others still.
