Should they be self isolating?

[Mylittlebubble]

My inlaws have just come back from New Zealand via Singapore (transit) with colds. They say the colds started before they got to Singapore so havent got Covid so won't be self isolating but undersrand if we dont want to see them for 2 weeks. I went on the 111.nhs website and did the questionnaire and it says to self isolate! I have mentioned it to them and sent them a link. Tried to call them to mention it again but they have gone out!!! Am i being neurotic or are they being naive????

They're being assholes.

You are right. They are being selfish and irresponsible.
Now is the time for containment.

Agree with pps.

Official advice states 'Stay indoors and avoid contact with other people if you’ve travelled to the UK from the following places in the last 14 days and have a cough, high temperature or shortness of breath, even if your symptoms are mild:'
(Singapore is listed).

They are being selfish, putting themselves and others at risk.

Definitely being selfish. There's corona virus in NZ too!

Well, have they got a cough, shortness of breath or a high temp? Or have they got a cold without any of the above?
