On July 21, 2022, the initial confirmed instance of polio in the United States in ten years was detected in New York. Health officials revealed that the virus was identified in Rockland County and was transmitted by an individual who had received the oral polio vaccine. This incident underscores the heightened importance for parents to comprehend the reasons behind vaccinating their children against polio.
Given that the United States has not utilized the oral vaccine for nearly two decades, experts speculate that the virus may have originated from overseas. The timing of the polio virus resurgence aligns significantly with National Immunization Awareness Month (NIAM), observed every August.

NIAM, an annual campaign, emphasizes the necessity of vaccinations throughout one’s life. Despite the absence of a cure, studies have shown that the polio vaccine boasts a 99% effectiveness rate.
The CDC recommends the polio vaccine for all youngsters and teenagers, administered in three separate doses. Authorities are strongly urging all unvaccinated individuals to receive the vaccine promptly.
Understanding Polio

While many individuals infected with the poliovirus remain asymptomatic, the disease can have severe effects on the nervous system, leading to muscle paralysis.
Although the disease has been around since the 1800s, its widespread impact began in the 1940s. Thousands of individuals were incapacitated annually, with summers often witnessing a surge in cases.

Among a group of 100 children infected with polio, 80% would exhibit no symptoms. The remaining 20% would display typical viral disease symptoms like fever, fatigue, and possibly diarrhea.
Paralytic polio, characterized by paralysis primarily in the legs, affected a smaller percentage of those infected. In cases where the virus paralyzed the respiratory muscles, it could prove fatal. The last reported instance of spontaneous polio infection in the U.S. was in 1979, largely due to widespread vaccination.
Impact of Polio on Children

While polio affects both children and adults similarly, its transmission is more common among children due to its fecal-oral route. Children are more susceptible to spreading the virus through inadequate hygiene practices.
The virus can be transmitted through contaminated hands to the mouth, primarily in restroom settings where handwashing is neglected.

Transmission through respiratory secretions like coughs or sneezes is less common.
Vaccination Timing for Children
The CDC reports that over 93% of Americans above the age of two have completed the recommended polio vaccine doses.

Children typically receive the first polio vaccine dose at two months, the second at four months, and the third between six to fourteen months. The fourth dose is usually administered at four to six years, coinciding with the start of elementary school. Proof of immunization, including polio vaccination, is mandatory for public school enrollment in all states and DC.
Minor side effects such as soreness at the injection site may occur, with very few individuals experiencing allergies. The vaccine’s high efficacy and minimal adverse effects make it a crucial defense measure.

Recent trends indicate a decline in vaccination rates, not due to reluctance but possibly because of reduced public gatherings and delayed preventive healthcare measures post-epidemic.
The recent polio case in New York underscores the importance of vaccination. Two counties in New York have detected polio in wastewater, suggesting prolonged virus circulation.

Individuals who have been vaccinated can be reassured amidst the recent outbreak, as they remain protected for life. While one case may seem insignificant, it could signal a larger issue for the unvaccinated population.
Despite the New York polio case, experts affirm that vaccinated individuals need not worry. Consult your child’s healthcare provider for any queries regarding their immunization history.
