Polio is a very serious disease that can cause paralysis in patients and also affect their intelligence. The most effective way to prevent polio now is to get vaccinated. Timely treatment at the onset of infantile paralysis can improve the prognosis. So, how to check for polio?
To confirm polio, medical examinations such as virus isolation and antigen testing are necessary. Within one week of onset, the virus can be isolated from the nasopharynx and feces, and the feces can remain positive for 2-3 weeks. In addition, isolating viruses from blood and cerebrospinal fluid in the early stages of the disease is of great significance.
When conducting virus isolation, tissue culture isolation methods are usually used. However, in recent years, some new detection methods have also been adopted, such as PCR, to detect viral RNA in the intestine. This can obtain faster results, such as tissue culture, and the accuracy is also very high.
Polio can also be diagnosed through serological tests, such as neutralization tests, complement binding tests, and other methods that detect specific antibodies. By using the above methods, doctors can confirm whether the patient has contracted polio. If confirmed to have contracted polio, it must be highly valued and treated immediately to alleviate the sequelae.
