hi there, sorry to know about your condition. As you must be knowing by now that HIV
infection is a potentially fatal condition and in span of several months to years it leads to AIDS
which is the manifestation of the infection. CD4 counts are highly prognostic and if they are low, the prognosis is bad. Usually people with HIV infection tend to have decreased immunity ie their body's natural defence mechanism is weakened and so they are not able to fight the so called harmless infections. Also they tend to get infected with atypical tuberculosis
bacteria which is difficult to treat with conventional medicines. Sore throat
is also a part of the same spectrum. Lets see if the antibiotics you are being treated with are effective or not and whether your body recovers its counts. Frankly the condition is grim but do have faith in your doctors and hope for the best. Take care.
