The 2010 California outbreak of the extremely contagious respiratory disease pertussis (also known as whooping cough) was the largest in more than 60 years. It resulted in 9,120 cases and 10 deaths -- a third of all the cases seen in the USA that year. Several causes of the outbreak have previously been documented, including waning immunity of the pertussis vaccine. A new analysis offers evidence that geographic areas with higher percentages of people who intentionally refused the vaccine is also associated with increased cases of the disease.
