Norovirus intestinal infections in children and adults: symptoms and treatment

Signs of norovirus intestinal infections in children and adults

Both adults and children often suffer from intestinal infections, which are caused by different pathogens. Among them is norovirus, which causes the development of so-called intestinal influenza. The symptoms and treatment of norovirus intestinal infections in children and adults a little different from the treatment of rotavirus infection, but certain differences still exist.

General characteristics of the virus

Noroviruses as a rotaviruses are considered the main pathogens of all intestinal infections. Rotavirus and norovirus was originally not distinguished, therefore the patients in all cases put the diagnosis – «rotavirus infection». In 1972, due to a number of genetic studies of norovirus allocated a separate group. It was found that this pathogen belongs to the family Caliciviridae.

Now 25 known strains of norovirus, each of which poses a risk to human health. Most often the causative agent, penetrating into the body, triggers the development of acute gastroenteritis, or intestinal flu. This bacterium is very contagious and easily transmitted from person to person.

The stomach flu is more prevalent in the cold season, although it can be transmitted and summer. The incubation period after entry into the body is 12 to 48 hours. During this time period a person does not feel sick, but can infect other people.

Mainly enteric norovirus infection occurs in the form of light. This disease is accompanied by unpleasant symptoms that completely disappear in 2-3 days, even without the help of a doctor. Medications are prescribed to accelerate the healing process or if the disease is unusually difficult.

Ways of transmission

An infectious disease begins after penetration into the organism of norovirus. There are three mechanism of transmission:

  1. Food – by eating poorly washed fruits, vegetables and berries. Most often, the infection occurs in summer in the period of mass ripening of fruit production.
  2. Water and infection occurs through ingestion of water, in which there are agents. This is typical for open ponds where the water is not chlorinated. In summer bathing in lake or river, you can catch the stomach flu.
  3. Contact-household – bacilli get into the intestinal tract via nedomytye utensils, dirty hands or some household items.

The person who contracted the norovirus, is considered to be contagious during the incubation period, during the acute phase, and about three days after complete subsiding of all symptoms.

After a full recovery occurs unstable immunity to the disease, which lasts no more than two months. After this period a person can get sick again intestinal infection.

Signs of the disease

First aid

The manifestation of the first symptoms norovirus infections can take a number of actions that will help the patient’s condition:

  • If severe vomiting can be washed stomach a weak solution of potassium permanganate. Because of this the body will be removed the most part of pathogenic organisms and decomposition products.
  • Do a cleansing enema, which uses salted water or solution regidrona.
  • The patient strenuously otpaivat to avoid dehydration. A suitable solution regidrona, which is given often, but in small portions. Young children drink this solution with great reluctance or even refuse to eat. In this case, a baby otpaivat compotes, fruit drinks or tea.

For otpevanie adults and children can not use carbonated drinks, kvass and milk. All of these products will further irritate the gastric mucosa and contribute to the growth of bacteria.

  • Give any absorbents, suitable even for the classical activated carbon, which is pre-ground into powder and diluted in a small volume of water.
  • Human intestinal infection is put to bed, to the side to avoid zahlebyvayas vomit.
