A study published in Clinical Infectious Diseases found that US cases of pertussis have risen significantly since 2000.
There was a significant increase in the incidence of pertussis over time, with a 1.7-fold rise in baseline rates between 2000-2008 and 2009-2016. Patients aged younger than 1 year and 19 to 64 years did not experience significant increases during that time.
According to the study, 339,420 pertussis cases were reported between 2000 and 2016. White (88.2%) and non-Hispanic (81.3%) people comprised the majority of patients, with 9.9% of cases resulting in hospitalization and 0.12% cases being fatal.
