Herpangina

Herpangina is an acute viral disease characterized by the appearance of painful vesicles on the palate and back of the throat. The main causative agent of this disease is the Coxsackie virus, which belongs to the group of enteroviruses. The infection is transmitted by the fecal-oral route, which contributes to its widespread distribution among children and adolescents in school and children's groups. Symptoms of herpangina include an acute onset with high fever, sore throat, profuse salivation, and may also be accompanied by dyspeptic disorders. In most cases, the disease proceeds favorably and ends in recovery within one to two weeks.

History of the disease and interesting historical facts

Herpangina was first described in medical literature at the beginning of the 20th century. In 1913, American pediatrician John L. Case published observations about this disease, which marked the beginning of its study. Later, with the beginning of active research into viruses, it was established that herpangina is caused by the Coxsackie virus, isolated in 1948. An interesting fact is that this disease was previously called "pharyngeal herpes". There are different outbreaks of herpangina, which are historically associated with changes in ambient temperature and living conditions of the population. In 1998, a large herpangina epidemic was recorded in Japan, affecting more than 10,000 people.

Epidemiology

The epidemiology of herpangina shows a high incidence among young children. Children aged 3 to 10 years are most susceptible to the disease, but cases of the disease can also be observed in adolescents, and in rare cases, in adults. Statistics show that the prevalence of herpangina increases significantly in the summer and autumn months, which is due to the greater activity of the Coxsackie virus in warm weather. According to the World Health Organization, about 2-5 million cases of herpangina are registered annually worldwide. It is important to note that almost all cases of the disease are benign and end in recovery.

Genetic predisposition to this disease

To date, no direct genetic predisposition to herpangina has been identified, but possible mutations in genes responsible for the immune response are being studied. In particular, it is assumed that hereditary factors may affect susceptibility to enteroviruses, including the Coxsackie virus. In people with weakened immunity, especially with genetic abnormalities in the immune defense system, the risk of developing more severe forms of herpangina increases. In particular, some studies show that polymorphisms in the genes encoding interferons may contribute to an increase in the incidence of the disease among certain population groups.

Risk factors for the development of this disease

Risk factors that contribute to the development of herpangina include both physical and chemical exposures. The main risk factors include:

• Contact with infected people, especially in children's groups.
• Poor sanitary and hygienic situation and failure to observe personal hygiene rules.
• Seasonal temperature variations: The highest number of cases occurs during the warmer months.
• A state of immunodeficiency that protects the body from infections.
• Concomitant viral infections such as influenza or adenovirus infections.

According to various studies, children with frequent respiratory infections have an increased risk of developing herpangina.

Diagnosis of this disease

Diagnosis of herpangina is based on clinical data and includes:

• The main symptoms are: high temperature (up to 39°C and above), severe sore throat, profuse salivation and dysphagia.
• Laboratory tests: PCR methods to determine the presence of Coxsackie virus in biological fluids.
• Radiological examinations: An X-ray may be required to rule out other upper respiratory tract diseases.
• Other types of diagnostics: serological tests to detect antibodies to the virus.
• Differential diagnosis: it is necessary to exclude tonsillitis of viral or bacterial origin, as well as other infections that manifest themselves in a similar way.

Timely diagnosis of herpangina contributes to rapid and adequate treatment of the disease, preventing the development of complications.

Treatment

Treatment of herpangina is mainly symptomatic and aimed at alleviating the patient's condition:

• General treatment includes bed rest, plenty of fluids and, if necessary, a soft food diet.
• Pharmacological treatment: analgesics and antipyretics such as paracetamol or ibuprofen are prescribed. In cases of severe pain syndrome, local anesthetics can be used.
• Surgical treatment: in most cases not required, however, if complications such as an abscess develop, surgery may be indicated.
• Other treatments include inhalations using antiseptics, gargling with sea salt or soda solutions to relieve sore throat.

The key to therapy is symptom management and patient comfort, as complete regeneration of the pharyngeal tissue occurs within a few days without the need for aggressive therapy.

List of medications used to treat this disease

• Paracetamol
• Ibuprofen
• Lidocaine (for local use)
• Saline solutions for rinsing
• Antiviral drugs in individual cases

These medications help relieve symptoms and promote faster recovery.

Disease monitoring

Herpangina monitoring includes:

• Control stages: dynamic monitoring of the patient's condition, including regular temperature measurement and assessment of the general condition.
• Prognosis: In most cases, the disease has a favorable prognosis, but in rare cases relapses or complications are possible.
• Complications: possible development of chronic sore throat or abscess.

Regular monitoring of patients, especially those predisposed to complications, can prevent the development of serious consequences.

Age-related features of the disease

Herpangina is mostly seen in young children. In children aged 1 to 5 years, the disease may be more severe due to the development of the immune system. Teenagers and adults may experience less severe symptoms, but the presence of chronic diseases may worsen the course of the disease.

Advice from Dr. Oleg Korzhikov

When dealing with herpangina, it is important to follow several recommendations:

• Keep your child on bed rest and drink plenty of fluids to reduce symptoms of dehydration.
• Use painkillers to control a sore throat, such as paracetamol or ibuprofen.
• Gargle regularly with saline solutions or herbal infusions to reduce inflammation.
• Monitor the development of symptoms - if they worsen, you should consult a doctor to adjust the treatment.
