10. Dry Cough
The sudden appearance of a dry cough which does not produce phlegm can be a sign of early HIV infection or late-stage AIDS.
In the case of early infection, most patients report experiencing flu-like symptoms such as fever, headache, and a dry cough. However, in patients with late-stage AIDS, a persistent dry cough represents a grave danger and a potential risk of death, as often it can be a sign of Pneumocystis, a severe respiratory infection caused by a yeast-like fungus called Pneumocystis Jirovecii.
