Responding to a spike in outbreaks, Southland residents and parents across the state were being urged by public health officials today to ensure their children have been immunized against pertussis, also known as whooping cough, and other dangerous diseases.
According to the California Department of Public Health (CDPH), more than 9,000 pertussis cases were reported in California in 2010, including 10 infant fatalities. That was the most cases in the state in more than 60 years.
