Borrelia recurrentisa is the causative agent of a disease that affects organs such as the skin, nervous system, cardiovascular system and musculoskeletal system. The main habitat for the infection are vertebrates and birds. No pathogen was detected among domestic animals. The route of transmission of infection from donor to recipient is contact-household method (transmitted through contaminated toys, clothing, bedding, household items, etc.). The carrier of the infection can be a tick, as well as other blood-sucking insects (mosquitoes, bedbugs, midges). Cases of transmission of the disease from mother to child are especially common. The incubation period of the disease lasts 3 weeks
Borreliosis most often affects the nervous system. It consists of the brain, spinal nerves, cutaneous branches of the cranial nerves and the central branches of the spinal nerves. In this case, the most dangerous is damage to the bulbar nucleus and roots, which ultimately leads to movement disorders and loss of voice. The peripheral nervous system is also under attack.
Diseases of the nervous system due to Borrelia recurrens infection are common. The immunity of patients who become infected with antibiotic therapy slowly weakens. In addition, a severe course can be manifested by myocarditis (inflammation of the heart muscles), hematological disorders (changes in blood composition) and carditis (inflammatory processes in the heart).
Symptoms of borreliasis disease can vary depending on the severity and location of the infection. The disease most often manifests itself as weakness in the limbs and abdomen, muscle pain, diarrhea, high fever, and sometimes weakness of the liver, kidneys and lungs in patients. In some patients, hearing may suddenly decrease, speech becomes uncertain, and even paralysis occurs.
Unlike many other infections, patients with Borreliosis may not have a painful reaction to the antigen at all. Against the background of infectious infection, a toxic form of the course, which is malignant, can also occur. The common antidote for both types of disease is vaccination, since cases have been reported over the past 5-7 years
