San Diego County public health officials are watching and waiting for another infectious disease epidemic, one that is especially dangerous for infants.
Whooping cough infections tend to be cyclical, peaking about every three to five years. The last big epidemic in San Diego County was in 2014. Based on historical patterns, health officials believe the region could experience another one this year or next.
In the meantime, the county is urging pregnant women to get immunized against the respiratory infection to protect their unborn infants.
Dr. Mark Sawyer, an infectious disease specialist at Rady Children's Hospital, discusses the looming whooping cough epidemic Tuesday on Midday Edition.
