Risks for in person working apart from COVID

[AchyCorazon]

Hi, this might be a slightly odd one. Both I and my partner work mostly work from home. However for my partner this is very formal and she has to get a special working arrangement agreed to get allow more than the normal number of days each week working from home. She needs to renew this arrangement soon, and is seeing her union rep about it tomorrow.

Part of why she is keen to do this is that both I and her Mum have angina, so she is concerned about possibly bringing COVID home and infecting one or both of us. However, she is also looking for as much ammunition as she can get to argue the case for home working. Are there other things she could be exposed to that would pose a risk to someone with heart disease? Colds & flu spring to mind but cannot think of anything else, and not getting far in searching on internet. If there isn't anything to worry about great, but please let us know if there is.

Any suggestions or comments appreciated.

Thanks

Dave
