How Do You Get A Sore Throat? What You Need to Do

A sore throat is an infection or irritation of the pharynx, the tube that connects your mouth and nasal passages to your esophagus and windpipe. Most cases are caused by viruses, like the ones that bring the common cold or flu, and they typically resolve on their own within a week. If you have a sore throat, the best approach is to manage the pain with rest, fluids, and over-the-counter remedies while monitoring for signs that point to a bacterial infection, which would require a doctor’s visit.

What Causes a Sore Throat in the First Place?

Viruses cause the vast majority of sore throats. Rhinoviruses, coronaviruses, adenoviruses, and influenza viruses all inflame the lining of the throat. When the immune system fights these invaders, the tissue swells, which triggers that raw, scratchy feeling.

Bacterial infections are less common but still significant. Group A Streptococcus bacteria cause strep throat, which accounts for roughly 1 in 10 adult sore throats and up to 3 in 10 in children. Unlike viral sore throats, strep throat often requires antibiotics to prevent complications like rheumatic fever.

Non-infectious causes exist too. Allergies, dry air, mouth breathing, smoking, and acid reflux can all irritate the throat lining. Post-nasal drip from allergies or sinusitis is a frequent culprit because the constant drip of mucus irritates the tissues.

How Do You Get a Sore Throat From Another Person?

Respiratory droplets are the main route. When an infected person coughs, sneezes, or talks, they release droplets containing the virus or bacteria. You can inhale those droplets directly, or you can touch a contaminated surface and then touch your eyes, nose, or mouth.

The germs can survive on hard surfaces like doorknobs, phones, and countertops for hours. Hand hygiene is therefore a critical defense. Washing your hands thoroughly with soap and water for at least 20 seconds is more effective than hand sanitizer against many respiratory viruses, though alcohol-based sanitizers with at least 60% alcohol work well when soap is unavailable.

Close contact matters. Living with someone who has a sore throat, sharing utensils, or kissing an infected person all increase transmission risk significantly. Children in school settings and adults in open-plan offices are at higher exposure simply because of proximity to others.

Is It Viral or Bacterial? How to Tell the Difference

The distinction matters because treatment differs. Viral sore throats do not respond to antibiotics. Taking antibiotics for a viral infection contributes to antibiotic resistance and offers no symptom relief.

Viral sore throats typically come with a cough, runny nose, hoarseness, or conjunctivitis. The throat pain develops gradually and is often accompanied by a low-grade fever. Bacterial strep throat, by contrast, usually hits quickly with severe pain, a high fever above 101°F, swollen lymph nodes in the neck, and white patches or pus on the tonsils. A cough is usually absent with strep.

No home test can definitively distinguish between the two. A rapid antigen test or throat culture performed by a clinician is the only way to confirm strep throat. If you have severe pain, difficulty swallowing, or a fever lasting more than 48 hours, see a healthcare provider for testing.

What Actually Helps a Sore Throat Feel Better?

Evidence supports several simple remedies. Warm saltwater gargles—half a teaspoon of salt dissolved in 8 ounces of warm water—can temporarily relieve pain by drawing fluid out of swollen tissues. Honey is another well-supported option. Research published in the Archives of Pediatrics & Adolescent Medicine found that honey was more effective than a common over-the-counter cough suppressant for nighttime cough and sleep difficulty in children. Do not give honey to infants under 12 months due to the risk of infant botulism.

Over-the-counter lozenges containing benzocaine or menthol provide temporary numbing relief. Acetaminophen or ibuprofen reduce both pain and fever. These medications do not treat the underlying cause, but they make the recovery period more bearable.

Hydration is essential. Warm liquids like tea with honey or broth soothe the throat, while staying hydrated keeps the mucous membranes moist. Cold foods like ice cream or frozen yogurt can also numb the pain temporarily. There is no evidence that dairy increases mucus production, so ice cream is not harmful during a sore throat.

Humidifiers add moisture to the air, which can ease throat dryness, especially if the air in your home is dry from heating. Avoiding smoke, both first and secondhand, prevents further irritation.

When Should You See a Doctor?

Most sore throats resolve without medical intervention, but certain symptoms warrant professional evaluation. Difficulty breathing, difficulty swallowing saliva, or drooling in a child are emergencies that require immediate care.

See a doctor if you have a fever above 101°F that persists, if the sore throat lasts more than one week, or if you see white patches on your tonsils. A sore throat accompanied by a rash, a stiff neck, or blood in your phlegm also requires medical attention.

Recurrent sore throats—defined as seven or more in one year—may indicate an underlying condition like chronic tonsillitis or reflux. In adults, a persistent sore throat that does not improve after two weeks, especially in someone who smokes or drinks alcohol heavily, should be evaluated to rule out more serious conditions.

Can You Prevent a Sore Throat?

Prevention focuses on reducing germ exposure and supporting your immune system. Frequent handwashing, avoiding touching your face, and staying away from people who are actively sick are the most effective strategies.

Do not share personal items like water bottles, eating utensils, or toothbrushes. During cold and flu season, consider wearing a mask in crowded indoor spaces, particularly if you are at higher risk for complications.

There is no vaccine for the common viruses that cause most sore throats, but the annual influenza vaccine reduces your risk of flu-related sore throats. The pneumococcal vaccine does not prevent strep throat because it targets a different bacterium.

General health habits matter. Adequate sleep, regular exercise, and a balanced diet support immune function. There is no specific food or supplement proven to prevent sore throats, so be skeptical of marketing claims suggesting otherwise.

The Bottom Line on Sore Throats

A sore throat is uncomfortable but rarely dangerous. The majority of cases are viral and resolve within 5 to 7 days with supportive care. Antibiotics are only useful for confirmed bacterial infections, which require a doctor’s evaluation.

Focus on symptom relief, stay hydrated, and rest. If your symptoms are severe, persistent, or accompanied by high fever, seek medical care. Trust your body’s signals—if something feels worse than a typical cold, it is worth getting checked.
