Is polio contagious?

Polio is a contagious disease that is mainly transmitted through the fecal-oral route or respiratory droplets. If infection is suspected, seek medical attention immediately.

The culprit of this disease is a pathogen called poliovirus, which can invade the human nervous system and cause paralysis or even life-threatening in severe cases. The main transmission routes include contact with contaminated food, water and saliva of infected people. It most often occurs in areas with poor sanitation or low vaccination rates, and children are more vulnerable because their immune systems are not fully developed.

After being infected with polio, symptoms may include cold-like fever, cough, general weakness, and stiff neck and back. In some cases, the virus may also attack the spinal cord, causing irreversible muscle paralysis. However, this disease does not cause serious consequences every time it is infected. Most people may show no symptoms, but they are still contagious, so you need to be extra vigilant.

In order to prevent this infectious disease, polio vaccination is the best way to protect children. Completing the vaccination according to the vaccination plan can significantly reduce the risk of infection. At the same time, we should also pay attention to hygiene habits in life, such as washing hands before and after meals, and avoiding drinking unclean water. If your child shows suspected symptoms, please seek medical attention as soon as possible without delay.
