ETIOLOGY, CLINICAL COURSE, AND PREVENTION OF POLYMYELITIS

This literature review provides a comprehensive overview of modern scientific data on the etiology, clinical course, and prevention of poliomyelitis. The analysis shows that the poliovirus primarily enters the human body through the fecal-oral route, initially replicates in the intestinal tract, and subsequently spreads to the central nervous system, affecting motor neurons. In recent years, the importance of modern diagnostic methods, particularly molecular-genetic and serological techniques, has significantly increased. In particular, the PCR (Polymerase Chain Reaction) method enables early detection of the virus by amplifying its genetic material (RNA), ensuring high sensitivity. The ELISA (Enzyme-Linked Immunosorbent Assay) method, in turn, detects antibodies produced by the immune system, allowing assessment of both the presence and stage of infection. According to the literature, the clinical course of the disease can vary widely, ranging from mild symptoms to severe complications, including flaccid paralysis. Immunization plays a leading role in prevention, and modern vaccines significantly reduce the spread of the disease. Overall, effective control of poliomyelitis requires early diagnosis, comprehensive vaccination, and strict adherence to sanitary and hygienic measures.
