DALLAS - Pertussis, commonly known as whooping cough, has taken six lives this year. The most recent was an infant this weekend in Dallas.
Whooping cough is highly contagious, and the six deaths this year are the most for a single year since 2005.
The death in Dallas led the state to issue a health advisory Thursday. They are urging children and adults who are around children to get the pertussis vaccine.
There were more than 1,100 cases of pertussis at the end of August in Texas. The state said that's double where we were at this time last year. 12 percent of the cases required trips to the hospital.
