Rotavirusny infection

Description:

Rotavirusny infection (RI, "intestinal flu") — the infectious disease caused by rotaviruses.  For this disease the acute beginning, moderately expressed symptoms of a gastroenteritis or enteritis, a frequent combination of intestinal and respiratory syndromes in an initial stage of a disease is peculiar.

Symptoms of the Rotavirusny infection:

The general nature of a disease has cyclic character. In one cycle the incubation interval (1-5 days), the acute period (is allocated 3-7 days, at heavy disease — more than 7 days) and the reconvalescence period — from armor. reconvalescentia — recovery (4-5 days).

The acute beginning — vomiting, sharp temperature increase, and diarrhea, often and very characteristic chair — for the second, third day gray-yellow and glinoobrazny is characteristic of a rotavirusny infection. Besides, most of the diseased has a cold, reddenings in a throat, they feel pains when swallowing. During the acute period there is no appetite, decadent stage of forces is observed. Long-term observations showed that the largest disease outbreaks arise in time or on the eve of a flu epidemic what it received the informal name for — "intestinal flu".

The Kcal and urine are very similar on signs to hepatitis symptoms (light kcal, dark urine, sometimes to blood flakes).

The disease is considered the nursery because organisms of adults are more protected from rotaviruses. At the adult acidity of a gastric juice is higher and the number of the developed secretory IgA is higher.

At adult RI it can be shown by small intestinal frustration therefore the infected person can not guess that it is sick. Often the disease proceeds at all asymptomatically. Usually if in a family or in collective is infected, then within 3-5 days also the others serially begin to get sick. It is possible to prevent infection from the infection carrier in case of active immune system.

The most frequent clinical course of a disease are enteritis and a gastroenteritis, a secondary lactose intolerance.

Reasons of the Rotavirusny infection:

Rotaviruses (Latin Rotavirus) — a sort of viruses from the Reoviridae family, similar on morphology and an antigenic structure. As well as other representatives of this family, rotaviruses possess the double-stranded fragmented RNA. In a genome of a virus of 11 fragments which are surrounded with accurately expressed three-layered fibrous casing (capsid) with ikosaedrichesky symmetry. Outward of particles reminds "a wheel with a wide nave, short spokes and accurately outlined rim" because of what they also received the name (Latin of rota — "wheel"). Diameter of virus particles is from 65 to 75 nanometers.

Treatment of the Rotavirusny infection:

Main objective of treatment is fight against results of impact of an infection on an organism: dehydration, toxicosis and related disturbances of cardiovascular and urinary systems.

First of all at treatment rehydration therapy is applied, reception of sorbents can be appointed (absorbent carbon, smectite dioctahedral, attapulgit). Effective antiviral drugs for fight against an active rotavirusny infection do not exist.

In the course of treatment — a rigid diet: porridges on water, apple compote. To exclude dairy products to an absolute recovery.

As an effective remedy against a rotavirusny infection of WHO recommends performing preventive vaccination.

According to the American gastroenterological association at treatment of the diarrhea caused by a rotavirusny infection, especially in small children and babies such probiotics as Lactobacillus rhamnosus and Lactobacillus casei can be useful.
