Sore throats are infections caused by bacteria or viruses. People usually recover quickly (usually after three or four days), although some develop complications. A serious but rare complication is rheumatic fever, which affects the heart and joints. Antibiotics reduce bacterial infections but they can cause diarrhoea, rash and other adverse effects and communities build resistance to them.

Causes, incidence, and risk factors
Pharyngitis is caused by swelling (inflammation) of the pharynx, which is in the back of the throat, between the tonsils and the voicebox (larynx).
Most sore throats are cauesd by a viral infection, such as the cold or flu. Some viruses can cause specific types of sore throat, such as coxsackie infection or mononucleosis.
Bacteria that can cause pharyngitis include Group A streptococcus, which leads to strep throat in some cases.
Other, less-common bacteria that cause sore throats include corynebacterium, gonorrhea, and chlamydia.
Most cases of pharyngitis occur during the colder months. The illness often spreads among family members.
