Mouse fever: symptoms and treatment

Infections carried by rodents can have very deplorable consequences for a person when they get into the body. One of these infections is murine fever, the symptoms of which appear in the initial stage in the form of an acute form of acute respiratory disease. Meanwhile, despite the direct relation to this category, the effects of infection are expressed not only in fever, as can be understood from the name, but also in kidney damage, general intoxication and thrombohemorrhagic syndrome. The danger of the disease lies in the fact that if you hit the kidneys with untimely started treatment, it can lead to a fatal outcome.



Virus Transmission

Vole mice, as well as Norwegian rats, act as carriers of the virus. In this case, the animals themselves do not get sick, but only suffer this virus. Isolation of it occurs through urine and feces of animals. Among the ways of infection are several of their types:


  • An airborne dust infection that inhales dust containing feces with a virus
  • Alimentary type of infection, in which food or water contaminated with secretions with a virus is used;
  • Contact type of infection, in which damaged skin contacts contaminated objects with a virus or directly with rodents infected with it.

There is no transfer of the virus from one person to another.

Mouse fever: symptoms, course of the disease

The duration of the incubation period can be on the order of 7-46 days, but the most frequent is the period of 21-25 days. The initial period, oligouric (characterized by hemorrhagic and renal manifestations), the period of polyuric and the period of convalescence are those actual periods of the course of the disease, which are characterized by murine fever. Symptoms of murine fever in children appear gradually, with their first manifestations can be seen only on the fifteenth, and even the twentieth day after the infection occurred. Among them are the following:


  1. Temperature rise up to 40 ° C;
  2. Muscle aches, joint pain

  4. Nausea with alternating vomiting
  5. Migraines of a frequent occurrence type
  6. Visual impairment
  7. Severe haemorrhage of the gums, as well as bleeding from the nose

There is a headache strong enough in its manifestation, the patient’s condition is accompanied by dry mouth, general weakness. Inspection reveals the presence of signs of skin hyperemia (neck, face, upper thoracic parts), a conjunctiva appears, in some cases a hemorrhagic rash appears.

2-4 — 8-11 days of illness . As in the past period, the disease is characterized by fever, which lasts up to 4-7 days. A decrease in temperature does not lead to an improvement in the general state, moreover, it may even worsen.

Treatment of murine fever

Treatment of this disease occurs in the infectious ward at the hospital. For him, it is characteristic to appoint a bed rest for a period of 1-4 weeks. Appoint antipyretic, analgesic and antiviral drugs, as well as anti-inflammatory drugs. Additionally, infusion therapy is prescribed, if necessary, glucocorticoids and hemodialysis are used. The development of thrombohemorrhagic syndrome requires the use of anticoagulants. In addition, vitamins and the elimination of drugs that promote kidney damage are relevant.
