On some websites they list a persistent dry cough as a symptom of ARS? Yet on thebody.com website, one of the doctors mentioned that a cough and respiratory ailments were not so much a symptom of early acute infection but rather it occurs later on in more advanced stages HIV?

P.S. On some sites that list percentages associated with symptoms, if i recall, a dry cough isn't considered a symptom.

Anybody have an idea?

Stop looking up symptoms on the internet because:

a) the answers will invariably conflict
b) you'll drive yourself crazy
c) you'll spend your entire life doing it
d) it can be confusing
