COVID-19 disrupted health care across the globe. causing the biggest drop in childhood vaccination rates in decades. UNICEF's latest estimates find that nearly 50 million children entirely missed out.
When public health specialists look at the annual case counts, some see a trend that raises questions about how realistic the goal of a polio-free world might be.
It was a big year for viruses, which simply refused to be ignored. And unlike the previous two years, COVID had to share the spotlight.
New York Gov. Kathy Hochul said the state is stepping up polio-fighting efforts as the virus was detected in the wastewater of another county in the New York City area.
As polio makes a comeback, Minda Dentler reflects on her life with the disease. Paralyzed as an infant in India, she's gone on to become a champion wheelchair triathlete and an immunization advocate.
Polio is spreading in a few New York counties with low vaccination rates. Experts warn that other places in the U.S. could face the same challenge.
The highly infectious viral disease can lead to permanent paralysis of the arms and legs and even death in some cases. Health officials are urging people to get vaccinated if they haven't been.
Children were made eligible for booster doses after health authorities reported finding evidence the virus has spread in multiple areas of London but found no cases of the paralytic disease in people.
The CDC confirmed that a patient in New York has contracted polio, the first U.S. case since 2013. But most people shouldn't be concerned about contracting the virus because of high vaccination rates.
The patient, who has developed paralysis but is no longer contagious according to the AP, may have contracted the virus overseas. The CDC says no cases of polio have originated in the U.S. since 1979.
Scientists in Britain have detected multiple versions of the virus in wastewater. Officials say the risk to the public is extremely low and urge people to ensure their polio vaccines are up to date.
Countries in Africa, the Middle East and parts of Asia are counting more cases of vaccine-derived polio. One reason for this, say experts, is that vaccination efforts have lapsed during the pandemic.
