The large majority of CSWs in Singapore and other eastern Asian countries do not have HIV
. As for your symptoms
, they started too soon to be due to HIV
; a week is the minimum and usually it's 10-14 days. And if it was HIV, the fever would continue for at least a week.
So as you were told on the community forum, if you caught anything from your commercial partner, it was just a common cold -- regardless of not having nasal symptoms.
