While cases of whooping cough are setting records in the Dallas area, we're seeing an increase, too.

“We're seeing three times the amount of cases that we normally see,” says Harris County Health Department Public Information Officer Porfirio Villareal.  “Pertussis is cyclical, so every four to five years we see an uptick in cases.”

Villareal says 163 cases have been confirmed so far.  He says the disease affects the most vulnerable.

“It's really important for pregnant women to get vaccinated during the third trimester,” he says.  “That way they pass on the antibodies when the baby is born because pertussis does affect babies the most.”
