**Surge in Pertussis Cases Affects Oregon, Washington, and Idaho**

Pertussis, commonly known as whooping cough, is experiencing a significant resurgence across Oregon, Washington, and Idaho this year. According to the Oregon Health Authority, the state has reported over 800 cases as of Wednesday and is on track to surpass its 2012 record of 910 cases.

The highly contagious bacterial infection is particularly dangerous for infants under one year old, the elderly, and those with compromised immune systems. In Oregon, the disease has spread to 23 counties, with Lane County recording the highest number at 249 cases. Multnomah County follows with 180 cases, Clackamas County with 109, Washington County with 67, and Deschutes County with 59. Tragically, the state has also reported one fatality involving an older adult.

Washington State has reported 1,193 cases so far in 2024, a sharp increase from just 51 cases during the same period last year. In Idaho, over 700 cases have been documented, compared to only 34 in 2023. In Washington, 31 counties have reported pertussis cases, with Whitman County showing the highest infection rate per 100,000 people, followed by Clark, Douglas, and Grant counties. The majority of Whitman County's 63 cases have been confined to the student population at Washington State University.

Hospitalizations are on the rise as well. Washington has seen 28 people hospitalized, including 12 infants under one year old. In Idaho, nine individuals have been hospitalized, comprising four infants, one child between one and four years old, two teenagers, and two adults over 50.

Pertussis symptoms usually manifest five to ten days after exposure. Early symptoms are similar to a common cold, but severe coughing fits, characteristic "whoop" sounds, and vomiting can occur as the disease progresses. Early treatment with antibiotics is crucial to preventing severe symptoms and further spread. Once the infection reaches an advanced stage, antibiotics are no longer effective, leaving patients to endure the illness for several more weeks.

Vaccination remains the most effective preventive measure. The Centers for Disease Control and Prevention (CDC) recommends a five-dose DTaP vaccination series for young children and a Tdap booster for adolescents and adults. Pregnant women are particularly urged to vaccinate, as immunization during pregnancy has shown to be highly effective in protecting newborns from pertussis.

While vaccines offer strong protection, their efficacy can wane over time. Hence, regular booster shots are advised for adults every ten years to maintain immunity. Alongside vaccination, good hygiene practices such as washing hands frequently and covering coughs can also help minimize the spread of the infection.
