Poliomyelitis virus is called poliovirus, and is mainly transmitted through the fecal-oral route, which means that the virus is contaminated by the patient’s digestive system through fecal matter, and that the patient comes into contact with the virus, which is mainly found in fecal matter. The fecal-oral route is the main mode of transmission due to the patient’s hygienic habits, lack of hand washing, contact with the virus in contaminated food in the environment, and eating contaminated food that passes through the digestive system. Some of the polioviruses can be transmitted through respiratory droplets, inhalation of virus-contaminated droplets can cause infection, and some patients can be infected with polioviruses through contact with vomitus, as well as through direct contact transmission.
