An outbreak of mouse fever is predicted in Tatarstan
Along with the onset of the dacha-barbecue season, the risks of contracting natural-focal infections rise sharply. One of them is HFRS or mouse fever. According to doctors, Tatarstan residents become infected with this disease more often than with tick-borne encephalitis and other infections. Last year alone, the incidence of HFRS increased by almost 3 times.
This year, Tatarstan is waiting for a peak in the incidence of hemorrhagic fever with renal syndrome (HFRS) or, as it is popularly called, mouse fever. This statement was made by the republican Rospotrebnadzor.
- The infection is very important for us, for our region. HFRS has a cycle of three to four years. In 2022, we recorded the peak incidence. This year, we also expect an increase in the number of cases, given that, according to the forecast, an increase in the number of rodents is also expected," Lyubov Avdonina , deputy head of the Rospotrebnadzor Office for the Republic, warned at a press conference.
Today, the republic is in 3rd place in terms of the number of cases of mouse fever among the regions of the Volga Federal District. The results of the incidence of last year increased by 2.7 times compared to 2021. So, for 12 months, 293 cases of HFRS were registered, the incidence rate was 7.9 per 100 thousand of the population. Moreover, men are more likely to become infected with mouse fever. They account for 80% of all cases. Children (5%), women and the elderly get sick less often.
One can only guess about the results of this year. So far, there are no Tatarstans infected with the fever in the region. The Rospotrebnadzor recalled that the incidence of HFRS is characterized by pronounced seasonality: from May to December.
"The next step is kidney damage"
European bank voles are the main reservoir, vector and source of human infection. The virus is contained in their blood and most intensively excreted from their body with urine, feces and saliva. Dried excretions of rodents rise into the air with dust when cleaning the premises, felling the forest, collecting brushwood for a fire, working with hay, as well as while smoking and eating with unwashed hands and enter the human body. It is worth saying that HFRS is not transmitted from person to person.
- Penetrating into the human body, the virus spreads into the endothelium, into the lining of blood vessels and lungs. Violation of their permeability can lead to the formation of microthrombi. All this can cause intoxication of the body, a cytokine storm, - explained the director of the Scientific and Clinical Center for Precision and Regenerative Medicine of the Institute of Fundamental Medicine and Biology of KFU, corresponding member of the Academy of Sciences of the Republic of Tatarstan Albert Rizvanov .
The incubation period of the disease can last more than 10 days. Often, people confuse mouse fever with SARS due to similar symptoms. The patient's body temperature rises to 38-40 degrees, he experiences headache, pain throughout the body and in the lower back, vomiting. Some patients have nasal congestion, cough, scleritis.
- It is rather difficult to make a diagnosis of HFRS at the first stage, since there are not enough clinical manifestations yet, - said the chief specialist in infectious diseases of the Ministry of Health of the Republic of Tatarstan Khalit Khaertynov.
The second stage includes the appearance of redness on the face and neck, possibly the appearance of conjunctivitis. Some patients lose visual acuity. These symptoms last from 1 to 9 days.
- The next step is kidney damage. In this period, pain in the lower back appears, there is a decrease in the amount of urine. There are visual disturbances. The duration of this period ranges from 5 to 10 days, then there comes a period when kidney function is restored, - the source said, adding that the healing process takes place under the obligatory supervision of a doctor. - Despite the fact that the infection is not transmitted from person to person, patients with HFRS are hospitalized in an infectious diseases hospital. Treatment is complex with antiviral drugs.
“Infection can happen anywhere, anytime”
Rospotrebnadzor called Tatarstan a natural focus of hemorrhagic fever with renal syndrome. The department explained that the republic is located in two zoological zones - forest and steppe. These two zones are the habitat of rodents, they account for more than 50% of all infections.
According to Albert Rizvanov, this year there is a high risk of infection in two locations - in the forests southeast of the village of High Gora and in the forests east of the village of Smak-Korsa. The expert explained that KFU scientists collected material and determined in which areas which strain of hantavirus is present. Biological material was taken from patients, with the help of which it was possible to identify which strain of hantavirus (the virus that causes HFRS - Ed.) is present in patients.
“Having carried out a genetic analysis, we determined that this strain could have arisen precisely at the border of different regions,” the interlocutor said, adding that the information received in the future will help develop effective methods for preventing the disease.
You can catch mouse fever not only in the forest and field. There are also household types of infection (about 30%), that is, you can “catch” the virus even at home, as well as in garden plots.
“Infection can occur anywhere, at any time,” Lyubov Avdonina warned.
It is worth saying that it is impossible to protect yourself from hemorrhagic fever with renal syndrome by vaccination, unlike many other diseases. There is no vaccine for the virus.
- Specific prevention of HFRS has not been invented yet, - confirms Halit Khaertynov.
According to the infectious disease specialist, the citizens of Tatarstan must take precautionary measures. When visiting the forest, fishing, hunting, wash your hands before eating, do not touch mice or their corpses with your hands. If facilities for handwashing are not available, use liquid skin antiseptics or wet wipes.
In apartments and houses it is necessary to carry out wet cleaning, especially for summer cottages. At the same time, Rospotrebnadzor recommends wearing a respirator mask, wearing gloves, special clothes and shoes. The same recommendation applies to other work, accompanied by the release of dust.
