Similar symptoms can occur with sinus infections and even with an allergy. Those that are a result of a strep infection show symptoms of being very sick, having a fiery red throat with white membranes over the tonsils, showing a bright red tongue, and enlargement of the lymph nodes underneath the jaw. Occasionally, there may be an associated bright red rash over the trunk. This type of infection needs to be treated with an antibiotic. Most of the other types of sore throats can be treated symptomatically.
Mononucleosis can also produce symptoms identical to strep.
This infection is caused by a virus and needs to be diagnosed by a physician. It will not respond to antibiotics and the only treatment is bed rest. Mono is distinguished by marked fatigue. A strep throat is treated with penicillin for 10 days. Most of the other sore throats are treated symptomatically with throat lozenges, gargles, and the use of decongestants or antihistamines if indicated.
