Polio is not a blood-borne disease. This is because poliomyelitis is mainly transmitted through the intestinal tract and the respiratory tract, but not through the blood. Transmission through the digestive tract mainly includes fecal-oral and oral-oral transmission; while respiratory transmission is mainly through droplet transmission, in which the patient speaks or sneezes and spreads droplets into the air, which may infect the population. In order to prevent the spread of polio, it is necessary to pay attention to dietary hygiene and water hygiene; wear a good mask when going out, avoid speaking to patients at close range, and receive polio vaccination in a timely manner. If you are concerned about contracting polio, you should seek medical attention as soon as possible and analyze the case through doctor’s examination, fecal virus isolation, and serum immune system tests. If early diagnosis and treatment can be made, the prognosis is generally good. –
