In the febrile state period, which lasts from 1 to 4 days, tiny grayish-white vesicles, 3 to 5 millimeters in diameter, surrounded by a reddish ring, appear in the pharynx and oral cavity (tonsils, uvula and soft palate). . When the condition is severe, injuries can also occur on the soles of the hands and feet.
Causes of Herpangina: Herpangina isusually caused by group A coxsackieviruses. However, it can also be caused by group B coxsackieviruses, enterovirus 71, and echoviruses. These viruses are highly contagious and can easily spread from person to person, especially in schools and childcare centres. People infected with Herpangina are most contagious during the first week of infection .
Herpangina is usually transmitted through contact with fecal matter. The infection can also be spread through contact with droplets from a sneeze or cough of an infected person. This means that you can get Herpangina if you touch your mouth after touching something that is contaminated with particles or fecal droplets from an infected person. The virus can live on surfaces and objects, such as countertops and toys, for several days.
Herpangina Diagnoses : Since ulcers caused by Herpangina are unique, your doctor can usually diagnose this condition by performing a physical exam. They will also review your symptoms and medical history. Special diagnostic tests are usually not necessary.
Herpangina Symptoms : Herpangina symptoms vary from person to person but can include:
- Sudden onset of fever;
- Sore throat ;
- Neck pain;
- swollen lymph glands;
- Difficulty swallowing;
- loss of appetite;
- Drooling (in babies);
- Vomiting (in babies).
Small ulcers at the back of the mouth and throat begin to appear about two days after the initial infection . They tend to be light gray and often have a red border. Ulcers usually heal within seven days.
- You should contact your doctor right away if you have:
- A fever that is higher than 106°F or that doesn’t go away
- Mouth sores or a sore throat that lasts for more than five days
- Dehydration symptoms such as;
- Dry mouth;
- Lack of tears;
- Decreased production of urine;
- dark urine;
- Deep eyes.
Herpangina Treatments: The disease is self-limiting and runs its course within ten days or so. Treatment aims to minimize the discomfort of symptoms and is only supportive: antipyretics, topical anesthetics in the oral cavity, antibiotics, in case of bacterial infections secondary to the virus, increased fluid intake, etc. Aspirin should be avoided due to its anticoagulant effects. As children may show difficulties in ingesting food and drinks, the doctor should be aware of possible dehydration.
