Suspected case at my DMs housing complex for the over 50's, coughing all over the communal garden. Am I being unreasonable?

[Roostersmum2]

My DM lives in a housing complex for older people, all of the residents flats are inside one main building and there is a medium sized communal garden for everybodies use.

One of mum's neighbours is a suspected covid case who remains untested, today he was in the communal garden sitting at the patio furniture outside mum's window coughing uncontrollably.

I do not begrudge the man fresh air and I genuinely hope he's going to be ok but I'm a bit concerned about this because of the other residents, and obviously my mum.

Should he be using that outdoor space when he needs to be in quarantine? The majority of residents are in their 70's and while it's awful that any of them have this at all, surely they need to be taking precautions to ensure it doesn't spread throughout the entire building?

To clear up any confusion, it is sheltered housing for the over 50's and is owned by the council.

I can't reach the warden on the telephone unfortunately. Mum is no longer using the garden but others are.

I am concerned about the coughing all over the furniture given that it's directly outside her living room window where she likes to sit and look out over the garden.

I think moving it is a good option but doesn't do much for minimising the risk to the other residents.

To access the garden you do need to walk through a communal lounge but unlike some other housing complex's mentioned here, that hasn't been blocked off.

OP - Do you know who the housing officer is for that complex or the housing manager - they will be able to help out I'm sure..
