Understanding Blister (Nonthermal) of Throat

Blister (nonthermal) of throat, also known as herpangina, is a viral infection that causes small, painful blisters or ulcers in the back of the throat and on the roof of the mouth. This infection is most common in children aged 3 to 10 years old but can also affect adults.

The most common cause of herpangina is the Coxsackie virus, although other viruses such as enterovirus and echovirus can also cause this condition. The virus is highly contagious and can spread through contact with infected saliva, mucus, or feces.

  1. Symptoms

    2. The symptoms of blister (nonthermal) of throat typically appear 3 to 6 days after exposure to the virus. The most common symptoms include:

    • Fever
    • Sore throat
    • Headache
    • Painful blisters or ulcers in the back of the throat and on the roof of the mouth
    • Painful swallowing
    • Nausea and vomiting
  2. Treatment

    3. There is no specific treatment for herpangina, and the virus must run its course. However, there are several things that can be done to relieve symptoms and speed up the recovery process:

    • Drinking plenty of fluids to prevent dehydration
    • Eating soft, cool foods such as ice cream or yogurt to soothe the throat
    • Taking over-the-counter pain relievers such as ibuprofen or acetaminophen to reduce fever and relieve pain
    • Gargling with warm salt water to relieve throat pain
    • Getting plenty of rest
  3. Prevention

    4. The best way to prevent the spread of herpangina is to practice good hygiene. This includes:

    • Washing hands frequently with soap and water
    • Avoiding close contact with people who are sick
    • Covering the mouth and nose when coughing or sneezing
    • Disinfecting surfaces and objects that may be contaminated with the virus
    • Staying home from school or work if you are sick

    If you or your child is experiencing symptoms of blister (nonthermal) of throat, it is important to consult with a healthcare provider for proper diagnosis and treatment.
