Herpangina: Symptoms, Causes, and How to Protect Your Family in Volusia County

Nothing disrupts a Florida summer faster than a feverish child who suddenly refuses to eat or drink. While many parents immediately fear "Hand, Foot, and Mouth Disease" or a severe case of Strep, the cause is often a condition called Herpangina. At Volusia Medical Center, we see a spike in these cases when the humidity rises. Here’s what you need to know to keep your family safe and manage the symptoms.

What is Herpangina?

Herpangina is a viral infection that mostly affects children between 3 and 10 years old. It causes small, blister-like sores on the roof of the mouth and the back of the throat. These sores can be very painful, and the main danger is not the virus itself, but the risk of dehydration if a child finds it too painful to swallow. Although the name may sound scary, it is a treatable condition if you know the signs.

Is Herpangina Related to Herpes?

We hear this question a lot in our DeLand and New Smyrna clinics. The answer is a definitive No.

• Herpangina is caused by Group A Coxsackieviruses, which are a type of Enterovirus.

• Herpes is caused by the Herpes Simplex Virus (HSV). Even though both can lead to mouth sores, they are caused by different viruses and need different treatments.

Both can cause mouth sores, but herpangina sores only appear at the back of the throat and on the soft palate. They usually do not show up on the lips or the front of the mouth like regular cold sores.

Is Herpangina Contagious? (And for how long?)

Yes, herpangina spreads easily. You can catch it from someone’s coughs or sneezes, or by touching things with the virus and then putting your hands in your mouth.

• How long is herpangina contagious? People are most likely to pass it to others during the first week they have symptoms.

• How long does it last? Typically, the fever goes away in 2 to 4 days, but the throat sores can last for 7 to 10 days.

Can Adults Get Herpangina?

Yes. We often see "the parent trap" where a caregiver catches it from their child. In adults, herpangina can feel like a devastating case of the flu combined with a severe sore throat. If you are an adult with a weakened immune system, you should be especially cautious and consider a preventive care consultation when nursing a sick child back to health.

Herpangina Treatments: Managing the Pain

Since herpangina is caused by a virus, antibiotics are not effective. At Volusia Medical Center, we focus on helping patients feel better while the illness goes away on its own, which usually takes 7–10 days.

1. Hydration is King: Florida's hot weather can cause dehydration quickly. Offer small, frequent sips of water, Pedialyte, or diluted apple juice.

2. The "Cold Diet": This is a good time to eat ice cream, yogurt, and ice pops. Stay away from acidic foods like orange juice or salty snacks, because they can make the sores hurt more.

3. Pain Management: Alternating between acetaminophen and ibuprofen can help manage the fever and make the throat pain less severe. Always consult our providers for the correct dosage for your child’s weight.

When to See a Doctor in Volusia County

While herpangina often resolves on its own, it can sometimes lead to complications like severe dehydration or secondary infections. You should come to our DeLand, New Smyrna Beach, or South Daytona offices right away if you notice any of these symptoms:

• Signs of Dehydration: No wet diapers for more than 8 hours, no tears when crying, or a "sunken" look to the eyes.

• High or Persistent Fever: A fever that lasts more than 3 days or doesn't respond to over-the-counter reducers.

• Inability to Swallow: If your child's throat hurts so much that they refuse to drink any fluids.

• Neurological Changes: If the patient has a stiff neck, a severe headache, or seems very tired, see a doctor right away, even though this is rare.

If you suspect you or your child might have herpangina, don't rely on searching online for answers. At Volusia Medical Center, our doctors are skilled at spotting viral infections and giving the right care to help your family recover. We provide thorough testing and treatment plans at all three of our easy-to-reach locations. Contact us and schedule a consultation today!

Conclusion

Herpangina is a common and painful illness that spreads easily at home and in schools. Knowing that it is caused by a virus called enterovirus—not herpes—and understanding how long it can be contagious will help you manage recovery. Drinking enough fluids and treating pain are the main ways to help, but seeing a doctor is always the safest option for your peace of mind. At Volusia Medical Center, we are dedicated to keeping families in DeLand, New Smyrna Beach, and South Daytona healthy all year round.

FAQs

1. How long does herpangina last?

• The fever usually goes away in 2-4 days, but the throat sores can last for about a week. Most people are fully better by day 10.

2. Can my child go to school with herpangina?

• No, not while they are sick. Your child should stay home until they have been free of fever for 24 hours (without using medicine to lower the fever) and are drinking enough fluids to join in daily activities.

3. Why did my child get this but not their sibling?

• Immunity is different for everyone. Older children may have already come into contact with some types of the Coxsackievirus, so they might not show symptoms even if they have the virus.

4. Is there a vaccine for herpangina?

• Right now, there is no vaccine for the viruses that cause herpangina. The best way to protect yourself is by washing your hands and disinfecting shared toys.

5. How is it different from Hand, Foot, and Mouth Disease?

• They are cousins! Both are caused by coxsackieviruses. The main difference is that Hand, Foot, and Mouth includes a rash on the palms and soles of the feet, while herpangina is localized to the throat.
