UMATILLA COUNTY — The Umatilla County Public Health Department reported there now are 21 cases of pertussis in the county, marking an increase in infections across the region.

The health department sent out an alert Wednesday, March 12, notifying the community about the ongoing whooping cough outbreak in the county.

“We are actively collaborating with school districts and other impacted facilities to promptly notify, contain the pertussis outbreak, and protect the health of our residents,” Umatilla County Public Health Director Joseph Fiumara said in the press release.

According to the Umatilla County Public Health, these cases have been identified in several regions of the county and affect individuals across various age groups.

Pertussis is a highly contagious respiratory disease that spreads easily through coughing and sneezing.

While it can cause severe illness, especially in infants, young children and those with weakened immune systems, many individuals experience only mild symptoms similar to those of the common cold. As a result, pertussis can often go undiagnosed and unintentionally spread to others who may be more vulnerable.

Umatilla County Public Health advises parents and community members to watch for early symptoms, such as a runny nose and mild cough. These can develop into prolonged coughing fits, sometimes with a “whooping” sound, difficulty breathing, vomiting after coughing and exhaustion.

Infants, pregnant women, unvaccinated individuals and those with weakened immune systems face the highest risk of severe illness.

“Vaccination, early detection and prompt treatment are critical in halting the spread of this disease,” Fiumara said.

The health department recommended if someone is unsure about their pertussis vaccination status, they should contact their primary health care provider for assistance. If an individual or their child develop symptoms, they should contact their healthcare provider immediately,

Individuals diagnosed with pertussis may need antibiotics and should stay home to prevent further spread.

Umatilla County Public Health will continue to monitor the outbreak and provide updates. For more information on pertussis symptoms, prevention and vaccine availability, visit Oregon Health Authority website or call Umatilla County Public Health at 541-278-6290.
