What causes sore throat?
Sore throat can be caused by infections, such as viral infection, which accounts for the commonest cause of sore throat. Common cold or flu (influenza), which is caused by viral infection can manifest with sore throat. Viral infections such as measles, chicken pox, mononucleosis and mumps can also cause sore throat.
Sore throat can also be caused by bacterial infection, with the commonest being the streptococcal infection, which is caused by Group A streptococcus bacteria, said to account for 40 percent of sore throat cases in children.
Sexually transmitted infections, such as gonorrhea and chlamydia can also cause sore throat. Individuals with HIV infection can also have sore throat and other flu-like symptoms, which sometimes appear early after someone is infected with HIV.
An HIV-positive person might have a chronic or recurring sore throat, due to a fungal infection called oral thrush or due to a viral infection called cytomegalovirus (CMV), which can be serious in people with compromised immune systems.
Environmental factors, such as dry air, especially in dry season, air pollution, exposure to cleaning agents and chemicals, as well as allergens, such as pollens and pets for people with allergies can cause sore throat.
Mechanical causes, such mouth breathing especially at night, some diseases like cancer of the throat, voice box or tongue and social behaviours like smoking of cigarette or tobacco smoke can result into sore throat.
Foreign body stuck in the throat, for example, a bone or piece of food can also cause sore throat. General anaesthesia has also been known to be a cause of postoperative sore throat. Trauma or injury, such as a hit or cut to the neck can cause pain and irritation.
Sore throat can also result from repeated use and strains on the vocal cords and muscles in the throat. It can occur after yelling or screaming, talking loudly, or singing for a long period of time without rest. Sore throats are a common complaint among fitness instructors and teachers, among others.
Sore throat is also seen in person with gastroesophageal reflux disease (GERD) a digestive system disorder in which stomach acids back up in the food pipe (esophagus). Intentional or unintentional ingestion: Certain substances, for example, bleach can cause a sore throat.

Factors that make one susceptible to sore throat include:
Age: Children and teens are most likely to develop sore throats. Children ages three to 15 are also more likely to have strep throat, the most common bacterial infection associated with a sore throat.
Exposure to tobacco smoke: Smoking and secondhand smoke can irritate the throat. The use of tobacco products also increases the risk of cancers of the mouth, throat and voice box.
Allergies: Seasonal allergies or ongoing allergic reactions to dust, moulds or pet dander make developing a sore throat more likely.
Exposure to chemical irritants: Particles in the air from burning fossil fuels and common household chemicals can cause throat irritation.
Chronic or frequent sinus infections: Drainage from the nose can irritate the throat or spread infection.
Close quarters: Viral and bacterial infections spread easily anywhere people gather, whether in child care centres, classrooms, offices or airplanes.
Weakened immunity: One is more susceptible to infections in general, if one’s resistance is low. Common causes of lowered immunity include HIV, diabetes, treatment with steroids or chemotherapy drugs, stress, fatigue and poor diet.
How is sore throat managed?
The management of sore throat involves making a diagnosis and its treatment. Usually, the doctor examines the throat with light and may feel for lumps round the neck. A throat swab is taken. Sore throat associated with bacterial infection like streptococcus is treated with antibiotics, and it is advisable that full course of antibiotics is taken to prevent complications like rheumatic fever, pneumonia and bronchitis.
A sore throat caused by a viral infection usually lasts five to seven days and doesn’t require medical treatment. If a sore throat is a symptom of a condition other than a viral or bacterial infection, other treatments will likely be considered, depending on the diagnosis. Medicines can be taken to relieve the pain of a sore throat, or to treat the underlying cause. The pain from sore throat can be relieved with some over-the-counter pain relievers, throat lozenges, throat spray that contains some numbing antiseptic like phenol, or a cooling agent like menthol or eucalyptus and cough syrup.
