As for your symptoms, while a flu-like illness can be a manifestation of early HIV
, when people with CLASSICAL flu-like symptoms
are studied, fewer than 1% turn out to have HIV
, the remainder having the flu or other common, non-STD viral illnesses. While some of your symptoms, like the fever and chills are seen in persons with HIV, pothers, like your cough are not. Thus your symptoms are not particularly worrisome.
If I were you I would not be worried about HIV from this encounter.
