There are a lot of recent posts where people are asking their risk factor. This is incalculable as everybody is different. You have to look at Government advice and make an informed decision. If you are offered the option to work from home take it. Maybe go in once or twice a week if necessary. I once worked in an air-conditioned open plan office where everytime you got over a cold you got another one.
If you have any specific worries please ring the BHF nurses. Bear in mind they will be extremely busy so if you know the answer listen to yourself and leave the resource for those in greater need! Thank you...
