A recent study shows that the significant rise in whooping cough cases may be connected to vaccinated people's not realizing they are infectious.
In 2012, there were approximately 50,000 whooping cough infectious within the U.S., the largest quantity since 1955. Infant death rates were three times higher than the remainder of the population.
A recent study conducted by Ben Althouse and Sam Scarpino, both of whom are Santa Fe Institute Omidyar Fellows, was published by BMC Medicine.
“There could be
millions of people out there with just a minor cough or no cough
spreading this potentially fatal disease without knowing it,” Althouse
said. “The public health community should act now to better assess the
true burden of pertussis infection.”
The study shows that there are different yet related sources for the whooping cough outbreak.
“It's the symptoms of pertussis infection that kill people, and the existing vaccine prevents the most debilitating effects of whooping cough,” Scarpino said.
They say that infectious vaccinated people do not have any whooping
cough symptoms and may unknowingly spread the illness.
“There are lots of people out there who may be transmitting pertussis unknowingly,” Scarpino said. “Not vaccinating your own child puts her or him at increased risk of severe disease, even death.”
