One of the main reasons for the spread of rotaviruses is non-compliance with personal hygiene rules, when transmission of infection occurs through hands, which in turn contaminate dishes, toys, and linen
The pathogen is transmitted through dirty hands, that is, the transmission mechanism is fecal-oral, although airborne droplets are also possible. It can affect people at any age, and the causative agent of rotavirus gastroenteritis is a virus from the order Rotavirus, family Reoviridae. Routes of transmission: contact and household (through dirty hands and household items); aqueous (when drinking water infected with viruses, including bottled water); nutritional (most often when consuming milk and dairy products).
The possibility of airborne transmission of rotavirus infection cannot be ruled out. But one of the main reasons for the spread of rotaviruses is non-compliance with personal hygiene rules, when transmission of the infection occurs through hands, which in turn contaminate dishes, toys, and linen.
The carrier of the infection is a sick person or a healthy virus carrier. The virus multiplies in the cells of the mucous membrane of the gastrointestinal tract and is excreted in the feces for up to 3 weeks (usually 7-8 days from the first symptoms of the disease). Damage to the mucous membrane of the digestive tract disrupts the digestion of food and leads to the development of severe diarrhea and dehydration. The main mechanism of transmission of rotavirus infection is through food. Infection occurs through the fecal-oral route.
Symptoms of rotovirus
Rotavirus or intestinal flu is highly contagious and spreads quickly in confined spaces. If one family member becomes ill, then with a high degree of probability the infection will be transmitted to everyone. Most often, patients complain of dizziness, nausea, weakness, chills, vomiting and diarrhea.
One of the leading symptoms of rotavirus infection is sudden onset of diarrhea.
During the course of the disease, there is an incubation period lasting up to 5 days, an acute period lasting 3–7 days, and a recovery period (4–5 days).
The onset of the disease is always sudden and is characterized by a sharp increase in temperature, as well as repeated increasing vomiting, cramping pain and rumbling in the abdomen, and the development of diarrhea is possible. The nature of the stool helps diagnose rotavirus infection. On the first day of illness, the stool is liquid yellow in color; in subsequent days, the stool becomes gray-yellow with a clay-like consistency. In addition to intestinal manifestations of the disease, patients are bothered by a runny nose, sore and sore throat, and cough.
The frequency of bowel movements often corresponds to the severity of the disease. If you have large, loose stools, dehydration may develop. From the very beginning of the disease, abdominal pain may be observed. More often they are moderate, constant, localized in the upper half of the abdomen; in some cases - cramping, strong. Signs of damage to the digestive organs persist for 3–6 days.
Rotavirus infection
Rotavirus infection is often also called rotavirus gastroenteritis or intestinal flu, although rotavirus does not belong to the influenza virus family. The route of transmission of the pathogen is fecal-oral, i.e. through dirty hands, although airborne droplets are also possible. Can affect people at any age.
The danger of self-medication for rotavirus infections
Not everyone infected with rotavirus develops the same disease. Its severity and duration depend not only on age, but also on the general condition of the person. What to do if you get sick? It must be remembered that sometimes very serious diseases can be hidden under the mask of ARVI, so it is necessary to exercise caution and immediately consult a doctor at the first signs of illness (vomiting, loose stools, rise in temperature). And if you have severe abdominal pain, do not take painkillers under any circumstances and call an ambulance immediately.
Treatment of rotavirus infection requires an integrated approach, so you should not self-medicate. The doctor will be able to assess the patient’s condition and, taking into account the severity of the disease, will select the necessary medications, including antiviral ones (for example, ARBIDOL®).
Signs of rotavirus infection
This is a disease with a short incubation period (1–5 days) and an acute onset with symptoms of gastroenteritis (on average 3–7 days, and in severe cases more than 7 days). Often, respiratory syndrome can also accompany the symptoms of gastroenteritis. The recovery period takes 4-5 days.
In children, this disease often manifests itself more acutely than in adults: a sharp rise in temperature, up to 39 degrees, vomiting and copious loose, watery stools. Vomit usually contains mucus, and nausea begins even from small portions of food and drink. With excessive vomiting and diarrhea, dehydration can occur, which poses a real danger to the child (8% fluid loss is life-threatening), and the ability to replenish fluid loss with drinking is complicated by an increased gag reflex.
In adults, nausea and vomiting are rare; manifestations of rotavirus infection are usually limited to moderate diarrhea, general weakness and a slight increase in temperature.
In addition to the symptoms of enteritis, the disease is accompanied by manifestations inherent to ARVI: runny nose, pain and redness in the throat, weakness, lack or loss of appetite.
Children are at high risk for severe and complicated acute respiratory viral infections and influenza. Their immune system is still imperfect and cannot always adequately fight off infection. Therefore, the risk of severe course and complications even with a common cold in children is much higher than in adults, therefore, they more often require treatment with antiviral drugs. Antiviral drugs used in pediatric practice must be well studied in preclinical and clinical studies, and must also have high efficacy and a favorable safety profile.
ARBIDOL® powder for suspension and 50 mg tablets are recommended for the treatment and prevention of influenza A and B, and other acute respiratory viral infections in young patients over 2 years of age, as well as in the complex therapy of rotavirus infection.
Prevention of rotavirus
Nonspecific prevention includes a set of sanitary and hygienic measures (regular hand washing, using only boiled drinking water, room ventilation, wet cleaning). Another important point is the timely isolation of a sick person who exhibits signs of acute respiratory viral infection and intestinal infection.
Gastroenterologists advise taking prebiotics and probiotics as a preventive measure. Probiotics, called “friendly bacteria,” are live microorganisms that aid digestion and improve protection against possible infections. Natural probiotics are found in fermented milk products: organic yogurt and cheeses, miso soup, sourdough bread, and sauerkraut. There are also probiotic supplements that come in capsules or drinks.
Arbidol® (Arbidol®)
Antiviral agent. Specifically inhibits in vitro influenza viruses A and B {Influenzavirus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), as well as other viruses that cause acute respiratory viral infections (ARVI) (coronavirus {Coronavirus) associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)). According to the mechanism of antiviral action, it belongs to fusion inhibitors, interacts with the hemagglutinin of the virus and prevents the fusion of the lipid membrane of the virus and cell membranes. It has a moderate immunomodulatory effect and increases the body's resistance to viral infections. It has interferon-inducing activity - in a study on mice, the induction of interferons was noted after 16 hours, and high titers of interferons remained in the blood up to 48 hours after administration. Stimulates cellular and humoral immune responses: increases the number of lymphocytes in the blood, especially T-cells (CD3), increases the number of T-helpers (CD4) without affecting the level of T-suppressors (CD8), normalizes the immunoregulatory index, stimulates the phagocytic function of macrophages and increases the number of natural killer (NK) cells.
Therapeutic effectiveness for viral infections is manifested in a decrease in the duration and severity of the disease and its main symptoms, as well as in a decrease in the incidence of complications associated with viral infection and exacerbations of chronic bacterial diseases.
In the treatment of influenza or ARVI in adult patients, a clinical study showed that the effect of the drug Arbidol® in adult patients is most pronounced in the acute period of the disease and is manifested by a reduction in the time for resolution of symptoms of the disease, a decrease in the severity of manifestations of the disease and a reduction in the time for elimination of the virus.
Therapy with Arbidol® leads to a higher frequency of relief of symptoms of the disease on the third day of therapy compared to placebo: 60 hours after the start of therapy, the resolution of all symptoms of laboratory-confirmed influenza is more than 5 times higher than the same indicator in the placebo group.
A significant effect of the drug Arbidol® on the rate of elimination of the influenza virus was established, which, in particular, was manifested by a decrease in the frequency of detection of viral RNA on the 4th day.
Refers to low-toxic drugs (LD50>4 g/kg). Does not have any negative effects on the human body when administered orally in recommended doses.
Use of Arbidol during pregnancy and children
The use of Arbidol during pregnancy is contraindicated.
It is not known whether the active substance of the drug Arbidol or its metabolites passes into breast milk in women during lactation. If it is necessary to use the drug Arbidol, breastfeeding should be stopped.

In Russia, the frequency of rotavirus gastroenteritis among acute intestinal infections is 7-35%, and among children under 3 years of age it exceeds 60%. The issues of treatment of rotavirus diarrhea still remain relevant. Considering the accumulated data on the persistence of rotavirus after rotavirus infection in follow-up, it is necessary to search for drugs that can increase the efficiency of rotavirus elimination.
The purpose of our study was to evaluate the effectiveness of the drug Arbidol against rotavirus infection in children aged 3-7 years.
A comprehensive clinical and laboratory observation was carried out on 70 children aged 3-7 years who were hospitalized at the Regional Children's Infectious Diseases Clinical Hospital in Saratov with a diagnosis of intestinal infection of rotavirus etiology. 40 children (group 1) received Arbidol in combination with basic treatment as part of therapy. The comparison group (30 children) received only basic therapy. The antiviral drug was prescribed orally at a dosage of 50 mg 4 times a day for 5 days. Laboratory diagnosis of rotavirus intestinal infection, as well as assessment of the elimination of rotaviruses during therapy, was performed by detecting rotavirus antigens using enzyme-linked immunosorbent assay in the acute period and during treatment.
It was found that in moderate to severe forms of the disease, the clinical effect of the drug is associated with a decrease in the duration of diarrhea syndrome (1.1 days less than in the comparison group) (p<0.05). The drug affected the duration of the intoxication syndrome (significantly less by 1.2 days than in the comparison group) (p<0.05). In the case of a moderate-severe form of rotavirus infection, during the use of an antiviral drug, the percentage of positive results in the detection of rotavirus antigens at the end of therapy decreased by 3 times (p<0.05); in the case of a severe form, positive dynamics of rotavirus elimination were also noted.
Thus, the inclusion of the drug Arbidol in complex therapy contributes to the intensification of the treatment of intestinal infections of rotavirus etiology in children: a more rapid regression of intoxication symptoms, a significant decrease in the duration of diarrhea syndrome, a decrease in the duration of rotavirus persistence (in the case of a moderate-severe form by 3 times, in the case of a severe form by 1 ,3 times).
