OHA release - Pertussis cases in Oregon have reached an all-time high with 1,475 reported cases as of Dec 10. Pertussis, also known as whooping cough, can cause severe disease in people of all ages.  Babies are most at risk of serious illness, hospitalization and death from infection. The American Academy of Pediatrics recommends every pregnant person receive a single dose of Tdap vaccine during their third trimester (weeks 27-36) to protect their newborn from pertussis. That's because babies' immune systems are too weak to protect against infection until they get vaccinated at 2 months old.  The best way to protect yourself and others is by getting vaccinated. In addition to pregnant people, pertussis vaccination is recommended for infants and children starting at 2 months through 4 to 6 years old, youth at age 11 or 12, and any adult who has not previously been vaccinated.
