Second Highest Numbers of Pertussis in Jackson County in Over Two Decades
Jackson County experienced the second highest numbers of pertussis (whooping cough) cases in over two decades.
Public health officials are encouraging people to ensure they and their families are up to date on vaccinations and to use other strategies to reduce the spread of respiratory illnesses.
Pertussis is a highly contagious bacterial infection that spreads through droplets when an infected person coughs or sneezes.
According to the press release from Jackson County Health and Human Services, pertussis often goes undiagnosed. The illness is tricky to diagnose because not everyone with pertussis will have the trademark “whooping" sound when coughing.
In 2025, 63 pertussis cases were reported to Jackson County Public Health. Among reported cases, 65% occurred among school-aged children and adolescents ages 5 to 19, and 19% occurred among children ages 1 to 4.
Vaccination status data indicate that 13% of reported cases were up to date on pertussis vaccination, 24% were undervaccinated, and 63% of the cases were not vaccinated or had an unknown vaccination status. As of December 27, 2025, a total of 1,541 pertussis cases were reported in Oregon, and one infant died earlier in 2025.
Jackson County Public Health recognizes pertussis activity may be concerning for families, particularly those with young children, and encourages families to review vaccination records and contact a healthcare provider if they have questions about pertussis vaccination or symptoms.
