Hi
@vermie , based on current guidelines, it may not be necessary to go to TTSH (since your friend has no symptoms he is 1st ring of exposure, and you are in ring 2) unless you have severe features of flu (breathlessness, etc) based on your situation.
Doing so may result in unnecessary waiting and time wastage on your end if they determine you are at low risk and turn you away. Instead, I would recommend a teleconsult or to visit your nearby GP clinic to determine if you have any severe features.
Note that although the teleconsult from home option through platforms like DoctorWorld is more convenient, if you are found to have severe features, you may still need to visit your nearby GP clinic to be examined and for them to assess if you are truly at risk and in need of testing in TTSH. Hope this helps!
