polio is a viral infection caused by the poliovirus, and it primarily affects the nervous system. Most people infected with poliovirus do not show any symptoms, and around 90% of cases are asymptomatic. These individuals are known as "asymptomatic carriers" and can unknowingly spread the virus to others.
In some cases, individuals may experience mild symptoms, such as fever, fatigue, headache, vomiting, and stiffness in the neck and back. This form of the disease is known as non-paralytic polio. The symptoms usually last for a few days to a week and resolve without causing permanent paralysis or disability.
In very rare instances, some individuals infected with the poliovirus may develop paralytic polio, which can lead to severe muscle weakness or paralysis, and in extreme cases, it can be life-threatening.
It's important to note that the vast majority of polio cases are mild or asymptomatic, and only a small percentage progress to the more severe forms of the disease. The best way to protect against polio is through vaccination. Vaccines have been highly effective in controlling the spread of polio and preventing its severe consequences.
If you have any concerns about polio or other infectious diseases, it's essential to consult with a healthcare professional who can provide accurate and up-to-date information based on the current situation.
