New York county confirms case of polio
|
"the virus may have originated in a location outside of the U.S."
Thank you, President Biden. | [FoxNews] The New York Department of Health on Thursday reported a case of polio in a resident of the state's Rockland County.
This case marks the first in the U.S. in nearly a decade.
The department said it was identified through sequencing at the Wadsworth Center — its public health laboratory — and confirmed by the Centers for Disease Control and Prevention (CDC).
The sequencing showed revertant polio Sabin type 2 virus.
"This is indicative of a transmission chain from an individual who received the oral polio vaccine (OPV), which is no longer authorized or administered in the U.S., where only the inactivated polio vaccine (IPV) has been given since 2000," the department wrote. "This suggests that the virus may have originated in a location outside of the U.S. where OPV is administered, since revertant strains cannot emerge from inactivated vaccines."
Polio is endemic in Afghanistan and Pakistan.
A viral disease that can affect the nervous system and cause muscle weakness, the polio virus typically enters through the mouth.
While it is usually transmitted by hands contaminated with the fecal matter of an infected person, respiratory and oral-to-oral transmission through saliva may also occur.
Polio is very contagious, and a person can spread the virus even if they aren't sick. The majority of people infected with polio have no symptoms.
Symptoms can be mild and flu-like and can take up to 30 days to present, during which time the infected individual can spread the virus to others.
Although rare, some cases can result in paralysis or death.
Due to the success of the polio vaccine, introduced in 1955, cases were cut dramatically in the late 1950s and early 1960s. The last naturally occurring cases of polio in the U.S. were reported in 1979, and the last known case in the country was recorded by the CDC in 2013.
