How to prevent Sore Throat. What are Bacterial Infection and Risk Factor related to Sore Throat

Sore Throat is caused by several types of bacterial infection. Here we discuss some major types of infection, Risk Factors, and Prevention. 

Bacterial Infections:- 

Several bacterial infections can cause a sore throat. The most common is Streptococcus pyogenes (group A Streptococcus) which causes strep throat.

Other Reason

Other causes of a sore throat include:

Allergies– Allergies to pet dander, molds, dust, and pollen can cause a sore throat. These problems get worse by postnasal drip, which can cause throat itching and swelling.

Dryness- Dry indoor air may cause your throat to feel rough and dry. Breathing through your mouth – often due to chronic nasal congestion – can also cause a dry, sore throat.

Jealousy. Outdoor air pollution and indoor pollution such as tobacco, chemicals, and smoke can cause chronic sore throat. Chewing tobacco, drinking alcohol, and eating spicy foods can also cause a burning sensation in your throat.

Muscle Strain. You can talk to your throat muscles by talking loudly, or for long periods of time without rest.

HIV infection. Other symptoms like a sore throat and flu sometimes appear after HIV infection.

Also, someone who is HIV positive may suffer from chronic or recurrent sore throat due to a fungal infection or a viral infection called cytomegalovirus (CMV).

Gastroesophageal reflux disease (GERD). GERD is a digestive system disorder in which the stomach acids return to the food pipe.

Other signs or symptoms may include hoarseness, regurgitation, heartburn, stomach contents, and a lump sensation in your throat.

Tumor. Cancer of the throat, tongue, or voice box (larynx) can cause a sore throat. Other signs or symptoms may include hoarseness, difficulty swallowing, noise, a lump in the neck, and blood in saliva.

Risk Factors-
Although anyone can get a sore throat, some factors make you more susceptible, including:

Age. Children and teens are most likely to have sore throats. Children ages 3 to 15 are also more likely to develop strep throat, the most common bacterial infection associated with a sore throat.



Exposure to tobacco smoke. Smoking and secondhand smoke is a major reason behind the irritation of the throat. The use of tobacco products also increases the throat, risk of cancers of the mouth, and voice box.

Allergies. Seasonal allergies or ongoing allergic reactions to dust, molds, 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 your nose can irritate your throat or spread infection.

Locked room. The viral and bacterial infection spreads easily where people gather, whether it is in child care centers, schools, offices, bus or train

Weak immunity. If your resistance is low, then you are more susceptible to infection in general. Common causes of low immunity include HIV, stress, diabetes, fatigue, treatment with steroids or chemotherapy drugs, and poor diet.


The best way to prevent a sore throat is to avoid the germs that cause them and practice good hygiene. Follow these tips and teach your child to do the same:

    1. Wash your hands thoroughly and repeatedly, especially before using the toilet, before eating, and after sneezing or coughing.
    2. Avoid sharing food, drinking glasses, or utensils.
    3. Cough or sneeze in a tissue and throw it away. When necessary, sneeze in your elbow.
    4. Use alcohol-based hand sanitizer as an alternative to hand washing when soap and water are not available.
    5. Avoid touching public phones or drinking fountains with your mouth.
    6. Avoid close contact with people who are sick.
