Swine flu in children causes symptoms similar to the clinical manifestations of the disease in adults. These include intoxication phenomena in the form of fever, headache, general weakness, etc. In childhood, the disease is severe and can lead to serious consequences for the child’s health.


The main cause of the development of infectious pathology is the swine flu virus H1N1. Once in the body of a child, it multiplies in the epithelium of the respiratory tract and causes clinical signs of the disease.

Infection of a child occurs in the following ways:

  • airborne – from a sick person or a virus carrier when talking, coughing or sneezing;
  • contact-household way when using common toys, utensils and personal hygiene products.

Children aged 3-4 often get sick when visiting kindergarten and other organized groups, such as creative circles, etc.

Clinical manifestations

Symptoms of swine flu in children occur acutely, usually within 10-12 hours after the virus enters the body. A sick child has a pronounced intoxication syndrome: an increase in body temperature to 39 C or more, general weakness, headaches, runny nose, pain in the joints and muscles, and lack of appetite. Progressive intoxication leads to nausea, vomiting and diarrhea.

Signs of damage to the respiratory tract in such cases are uncharacteristic. However, some children may have redness of the throat, a “dry” cough without sputum. In the absence of therapy, lung damage increases. There is shortness of breath, a feeling of lack of air, the child becomes restless, which indicates the development of respiratory failure.

In children under 4-6 years of age, the disease is severe, which is associated with the immaturity of the immune system. The phenomena of intoxication and dehydration against the background of vomiting and diarrhea pose a threat to the health and life of the child.

Negative consequences

The first signs of influenza are an indication for contacting a medical institution. In the absence of effective therapy, the disease progresses rapidly, leading to the development of complications from the internal organs. Swine flu, as well as bird flu, is characterized by their appearance already on the 2nd-3rd day of the disease. The following pathological conditions may occur:

  • pneumonia of a viral or bacterial nature. The influenza virus causes a strong decrease in the activity of the immune system, which creates favorable conditions for other pathogens;
  • hemorrhagic manifestations with the occurrence of hemorrhages in the skin, internal organs, etc.;
  • late infectious-allergic processes that occur 3-4 weeks after an acute infection. These include damage to the myocardium, heart valves, articular surfaces, etc.

A terrible complication of swine flu is respiratory failure. It develops against the background of viral pneumonia. Mortality reaches 20-25% of patients.


The symptoms of swine flu are similar to those of a normal flu infection. This makes it difficult to make a timely diagnosis and prescribe therapy. Diagnostic measures are carried out according to the following algorithm:

  1. Collecting the child’s complaints. The doctor talks with the child and his parents.
  2. During an external examination, the function of the lungs and the cardiovascular system is assessed.
  3. To confirm the infectious agent, PCR is performed on smears from the mucous membrane of the child. The method is highly sensitive.

When diagnosing swine flu, the epidemiological situation in the region is taken into account. If it previously had cases of detection of infection, then the likelihood of detecting this form of influenza increases.

Treatment approaches

swine flu treatment

Swine flu therapy is carried out in a medical institution. Children are hospitalized, as the disease can lead to severe respiratory failure and other complications within 2-3 days. Treatment includes antiviral and symptomatic agents.

The use of antiviral agents approved for use in childhood and blocking the reproduction of the virus in epithelial cells is effective. The drug is not prescribed for children under 1 year of age. Of the symptomatic medications, antipyretic and analgesic drugs of a non-steroidal nature are used.

Only a doctor should prescribe medication. The drugs have certain indications and contraindications that affect the effectiveness and safety of therapy.

Swine flu in childhood is severe and often leads to complications. This is due to the immaturity of the immune system. Timely seeking medical help from a doctor allows you to confirm the diagnosis and choose an effective therapy. Self-administration of medicines or traditional medicine is unacceptable. The disease can lead to the rapid death of the child against the background of respiratory failure.
