The dramatic resurgence of whooping cough is due, in large part, to vaccinated people who are infectious but who do not display the symptoms, suggests a new study by two Santa Fe Institute researchers in BMC Medicine. The study suggests that the number of people transmitting without symptoms could be many times greater than the number of people transmitting with symptoms - and much higher than previous estimates.
