Acute Pharyngitis: Symptoms, Causes, Treatment, and When to See a Doctor?

What Is Acute Pharyngitis?
Acute pharyngitis is a sudden infection or inflammation of the throat that typically causes a sore or painful throat. The most common reason is viruses, but bacteria such as group A Streptococcus can also cause it.
Most simple or casual viral sore throats will resolve themselves in about a week’s time. Antibiotics usually aren’t helpful when a virus is involved.
What Are the Common Acute Pharyngitis Symptoms?
Acute pharyngitis symptoms can be different depending on the underlying cause. Common symptoms include:
- Sore, dry, or scratchy throat
- Pain or difficulty when swallowing
- Redness or inflammation in the throat
- Fever
- Swollen or tender lymph nodes in the neck
- Swollen tonsils, sometimes with white patches
- Headache or tiredness
A cough, runny nose, hoarseness, or pink eye are may be warning signs of a viral infection. Sudden throat pain, fever, swollen neck glands, and inflamed tonsils can occur with group A strep infection.
What Causes Acute Pharyngitis?
Most cases of acute pharyngitis are caused by viruses. Common viral give rise to infections associated with colds and flu. Group A Streptococcus is the most common bacterial cause of strep throat.
Other factors can irritate the throat or contribute to throat discomfort, including:
- Smoking or second hand smoke
- Allergies and postnasal drip
- Dry air
- Acid reflux
- Vocal strain
Because viral and bacterial infections may have similar symptoms, a healthcare professional can recommend a throat swab when strep infection is suspected.
How Is Acute Pharyngitis Treated?
The acute pharyngitis treatment depends on its cause. Viral infections usually need supportive care rather than antibiotics, while confirmed group A strep infections are treated with antibiotics prescribed by a healthcare professional.
For symptom relief, you can:
- Drink plenty of fluids.
- Gargle with warm salt water.
- Choose soft or cool foods if swallowing hurts.
- Rest adequately.
- Use a humidifier or cool-mist vaporizer.
- Consider appropriate over-the-counter pain or fever medicine after checking the label or asking a healthcare professional.
Honey may be effective for coughs in children 1 year of age, older and adults. Children should be given medicines based on the directions for their age.
Do not start antibiotics on your own. They do not work against viral infections and unnecessary use can cause side effects and antibiotic resistance.
When Should You Consult a Doctor for Acute Pharyngitis?
If your symptoms are severe, are getting worse, or aren’t improving after several days, seek medical attention. Medical evaluation is particularly important if you have difficulty breathing or swallowing, excessive drooling, dehydration, blood in saliva or phlegm, a rash, or significant swelling.
If you have trouble in breathing or swallowing, are drooling, hear a high-pitched breathing sound (stridor), or notice that severe symptoms are getting worse quickly, get emergency medical help. These are warning signs of a serious problem with the throat or airway.
Can Acute Pharyngitis Be Prevented?
Good everyday hygiene can reduce the spread of infections. Wash your hands regularly, avoid close contact with people who are sick, cover coughs and sneezes, and avoid smoking or second-hand smoke.
