Microsoft Corporation (NASDAQ:MSFT) co-founder Bill Gates says the detection of polio in New York's wastewater is an "urgent reminder" that the debilitating disease must be eradicated.

What Happened: Gates made his comments on Twitter and shared a story from the New York Times on the discovery of the polio virus in wastewater samples taken in several locations, at different times, in two counties north of New York City. 

"News that polio has been detected in New York wastewater samples is an urgent reminder: until we [EndPolio] for good, it remains a threat to us all," said the billionaire.

Why It Matters: The discovery of polio from wastewater samples is a potential signal of community spread of the disease, according to the Times.

"Based on earlier polio outbreaks, New Yorkers should know that for every one case of paralytic polio observed, there may be hundreds of other people infected," said Mary T. Bassett, New York's health commissioner, according to the Times.

Bassett said the department is treating the single case of polio confirmed in New York as "the tip of the iceberg."

That case was discovered in an unvaccinated adult in Rockland County, New York — the first in the United States since 1979, according to the report. 

Last month, Gates warned that polio could spread back globally after the virus was detected in London's sewage.

At the time, the U.S. Department of Health had recommended that unvaccinated individuals get inoculated soon and people could opt for booster doses.
