The Rockland Department of Health has confirmed that an infant was rushed to the emergency room for whooping cough.

News 12 is told the child reportedly contracted the highly contagious infection in Spring Valley.

The infant is just one of 11 confirmed cases of whooping cough in Rockland County.

Doctors say at first, the highly-contagious pertussis appears to be a common cold with a low fever, runny nose, sneezing and a cough.

In just a couple of weeks, the cough worsens resulting in coughing fits.

Officials say it can cause serious and sometimes life-threatening complications, especially in young children and babies.

“Now is the time to make sure you and your family members are up to date on your vaccinations,” says Rockland Health Commissioner Dr. Patricia Schnabel Ruppert.

The warning comes as health officials continue to urge residents to get vaccinated for the measles, as there are currently 95 confirmed cases in Rockland.

While the county says the number of pertussis cases have been on the decline since 2015, it says it will continue to monitor the situation to keep residents informed.
