Oregon Overdose Deaths Are Down, CDC Data Shows -05/16/25

Oregon overdose deaths are down, CDC data shows

OHA continues to focus on programs with proven impact to get at root causes of addiction, address behavioral health needs across Oregon

PORTLAND, Ore.—Oregon’s overdose deaths decreased 22% between December 2023 and December 2024, a trend similar to that experienced nationwide, according to provisional Centers for Disease Control and Prevention (CDC) data.

“It is heartening to see this decrease in deaths due to overdose in Oregon, but the total still remains far too high, impacting families and communities across our state,” said Dean Sidelinger, M.D., M.S.Ed., health officer and state epidemiologist at the OHA Public Health Division. “We must continue to work together to keep people safe and build treatment and recovery supports for people struggling with substance use disorder.”

The count is still much higher than pre-pandemic years, with 1,480 deaths within that one-year time span, CDC data show. The preliminary data signify a decrease in fatal and nonfatal overdoses in Oregon from 2023 to 2024.

The decreasing trend is likely due to a combination of factors, including strengthened substance use treatment infrastructure, naloxone distribution and education, prevention programs, and changes in the illicit drug supply with less fentanyl overall.  This is good news, officials say, but work to reduce drug use and overdose is as important as ever.

While a decrease in overdose deaths is notable, Oregon’s substance use and overdose rates represent an ongoing and complex public health crisis created by multiple social, economic and systemic factors. Implementing a population health approach includes both upstream and downstream initiatives that can decrease substance use initiation and promote improved quality of life and well-being among Oregonians.

Some specific investments that are contributing to Oregon’s decrease in overdoses include the following:

Save Lives Oregon Harm Reduction Clearinghouse

• The Save Lives Oregon Harm Reduction Clearinghouse works with any organization that wants support in responding to the fentanyl crisis. The Clearinghouses began with six agencies and now works with more than 380 agencies across the state. All these agencies are locally oriented. These partnerships are with diverse groups that meet members of the community in a wide range of settings and circumstances.

Opioid treatment programs

• Oregon has been steadily increasing the availability of opioid treatment programs (OTPs). There are 27 full-service OTPs in Oregon, two OTP medication units, and four mobile OTP units. This includes nine new OTP sites over the last biennium.
• Oregon also expanded telehealth for medications for opioid use disorder (MOUD) and removed of prior authorizations for MOUD.

Residential treatment capacity

• In June 2024, OHA published a landmark study on the state’s residential treatment capacity. That study has been the foundation for immediate and long-term investments to increase residential capacity across the state. Currently, 260 beds dedicated to SUD treatment are in development and 41 beds dedicated to withdrawal management are in development.

Behavioral Health Regional Networks (BHRNs)

• BHRNs are funded through cannabis tax revenue, Drug Treatment and Recovery Services Funds. Between 2022 and 2025, $414 million has been allocated to BHRNs statewide.
• BHRNs assess their communities’ needs and tailor programming and services across six core areas: screening and assessment, harm reduction, housing services, substance use disorder (SUD) treatment, supported employment and peer support services.
• Engagement across every category of service has grown steadily since 2022, with particularly notable increases for peer support services, SUD treatment, and harm reduction services

Investment in the peer support services and system

• Peer services for individuals with substance use disorder (SUD) in Oregon are designed to provide support, guidance and encouragement from individuals who have lived experience with recovery.
• These services foster connection, reduce stigma and empower individuals on their recovery journey.
• Programs supported by the OHA focus on harm reduction, recovery planning and building healthy relationships.
• These services are available in every county.

Mental Health Awareness Month Spotlight: Loneliness line supports seniors

PORTLAND, Ore.– When Carli Cox picks up the phone, she never knows who will be on the other end, but she knows why she’s answering.   As a Crisis Intervention Specialist at Lines for Life, Cox is one of the voices providing support to people facing behavioral health challenges including loneliness.

For Mental Health Awareness Month, Oregon Health Authority is highlighting its partnership with Lines for Life. OHA provides funding for six crisis and support lines, including the Senior Loneliness Line.  This service offers older Oregonians connection and emotional support amid growing concerns about social isolation in aging populations.

“The Senior Loneliness Line is unique,” Cox said. “It functions both as a warm line for friendly conversation and as a space for crisis support when needed. We get calls from people who just want to start their day with a voice on the other end, to others who are dealing with isolation, loss, aging related issues, and sometimes suicidal thoughts.”

About 15% of Oregonians are ages 65 years or older, and by 2030 that number will increase to 20%. This age group is experiencing many behavioral health struggles, with one in five individuals experiencing depression at any given time. Males ages 75 and older have the highest suicide rate of any age group and gender.

With more than three years of experience and 4,000 crisis calls under her belt, Cox plays a critical role in helping the aging population.  Older adults often face stigma seeking mental health support, and Cox wants them to know that no problem is too small.

“Many seniors didn’t grow up in a time when talking about mental health was encouraged. We want them to know this line is here for them—it’s safe, confidential, and there’s no need to be in crisis to call.”

The Senior Loneliness Line sees a wide range of callers, from those facing estrangement from family to those who’ve outlived loved ones. Even a single phone call can bring meaningful change.

“Sometimes, you can hear a shift in someone’s voice by the end of a conversation,” said Cox. “Making that connection is so rewarding.”

If you are a senior or know someone who might benefit from the Senior Loneliness Line, please call 1-800-282-7035 or visit https://seniorlonelinessline.org/. For other mental health needs, call, or text 988 or chat online at 988lifeline.org.

Oregon Reports Record-high Nonmedical Vaccine Exemptions For Kindergartners -05/15/25

Oregon reports record-high nonmedical vaccine exemptions for kindergartners

But most families continue to vaccinate their kids, OHA officials say

PORTLAND, Ore.—A record 9.7% of kindergartners claimed nonmedical exemptions from Oregon’s school vaccination requirements for the 2024-2025 school year, the highest rate ever recorded in the state, Oregon Health Authority announced today.

The increase continues an upward trend from 8.8% in 2024, when Oregon had the fourth-highest nonmedical exemption rate in the United States, behind Idaho, Alaska and Utah, according to the Centers for Disease Control and Prevention (CDC). National data for the current school year are not yet available.

Data from the Oregon Immunization Program at OHA’s Public Health Division indicates 86.3% of kindergartners were fully vaccinated with all required immunizations for the current school year, down from 86.4% last year, marking three consecutive years of declining vaccination coverage among Oregon’s youngest students. These declining rates raise the risk of outbreaks of vaccine-preventable diseases in schools, particularly in communities with lower immunization coverage.

Stacy de Assis Matthews, school immunization coordinator at the Oregon Immunization Program, stressed the critical role of high vaccination rates in protecting public health.

“An immunized community is our most effective defense against diseases such as measles,” Matthews said.  “Robust vaccination coverage not only protects individual children but also safeguards those who cannot be vaccinated due to age, medical conditions, or other vulnerabilities, helping protect our communities in Oregon.”

• To view a video of local public health authority representatives from around Oregon sharing their thoughts about vaccine perceptions in their communities, click here.

Paul Cieslak, M.D., medical director for communicable diseases and immunizations at OHA, expressed alarm at the rising exemption rates.

“The increase in nonmedical exemptions weakens community immunity, creating opportunities for outbreaks of serious diseases that vaccines have nearly eradicated,” he said.

Cieslak cited CDC data reporting 1,001 measles cases in the U.S. as of May 8, 2025, with 96% among unvaccinated individuals or those with unknown vaccination status.

Dean Sidelinger, M.D., M.S.Ed., health officer and state epidemiologist at Oregon Public Health, highlighted the importance of sustaining and strengthening public confidence in vaccination programs.

“Vaccines have transformed public health by dramatically reducing the burden of infectious diseases, enabling children to grow up in safe environments,” Sidelinger said. “The growing trend of nonmedical exemptions threatens to undo decades of progress and puts us all at risk. OHA is committed to providing accessible, science-based information to empower families to choose vaccination.”

Despite the rise in exemptions, Matthews emphasized that the vast majority of Oregon families continue to get childhood immunizations. For students across all grades, from kindergarten through 12th grade, 90.4% were fully vaccinated in 2025.

“Parents and guardians recognize the essential role vaccines play in keeping schools and communities free from diseases like measles, polio, and pertussis,” she said. Oregon’s immunization laws help protect more than 650,000 students in schools and child care programs. “Every child’s immunization record is checked yearly, helping ensure equitable vaccine access for all Oregon children.”

Updated kindergarten immunization and exemption rates for the 2024-2025 school year are available at Oregon Immunization Coverage. Spreadsheets detailing immunization rates for individual schools and child care facilities are also accessible, with 2025 updates to interactive maps forthcoming.

Vaccination resources for families: 

• Information on immunization requirements in 17 languages can be found on the OHA website.
• Families seeking vaccines can contact 211 or their local health department. 211Info offers support in English and Spanish, with interpreter services in multiple languages.
• The Vaccines for Children program provides low- or no-cost immunizations for children ages 0-18 who are enrolled in Oregon Health Plan, uninsured, and/or American Indian/Alaska Native. 

Increasing awareness and education about primary prevention, public health risks and preventive health services are among actions OHA is taking as part of its 2024-2027 Strategic Plan. The plan further supports expanding access to vaccines and other health resources for children, parents and families in all communities in Oregon.

About OHA: Oregon Health Authority is dedicated to improving the health and well-being of all Oregonians through evidence-based public health initiatives, including robust immunization programs.

Syphilis During Pregnancy On The Rise, Leading To Serious Health Complications For Infants -05/13/25

Syphilis during pregnancy on the rise, leading to serious health complications for infants

OHA public health physician says coordinated action, increased awareness and commitment to equitable care can help protect those most at risk

PORTLAND, Ore. —Health care providers in Oregon are deeply concerned that congenital syphilis rates continue to rise at an alarming pace, according to preliminary 2024 Oregon Health Authority data. This is despite overall rates of sexually transmitted infections (STIs) in Oregon stabilizing in recent years.

In 2014, Oregon recorded two cases of congenital syphilis. By 2024, that number had surged to 45—a staggering 2,150% increase—according to data analyzed by the HIV, STD and TB Section at OHA’s Public Health Division.

“Although rates of syphilis infections in Oregon have decreased in line with national trends, the rate of syphilis diagnosed during pregnancy is increasing, resulting in more infants affected by this preventable disease,” said Pete Singson, M.D., OHA’s HIV, STD and TB medical director.

“Congenital syphilis cases remain concentrated in urban areas, but we’re seeing a growing number of syphilis cases during pregnancy in rural and frontier counties,” Singson explained. “Half of the 2024 congenital syphilis cases were outside the Portland metro area.”

Pregnant people in the Black/African American, American Indian/Alaska Native, Native Hawaiian and Pacific Islander, and Hispanic/Latino populations in Oregon are disproportionately represented in this epidemic.

Singson said it’s critical to understand that these disparities are not due to race or ethnicity, but rather by the compounded effects of systemic racism, poverty, houselessness and stigma.

The risks of untreated syphilis during pregnancy include miscarriage, growth abnormalities, premature birth and fetal death. In a newborn, nearly every organ system can be affected, and severe cases can result in neonatal death. Providers have limited experience diagnosing syphilis due to its historically low prevalence, Singson said, which makes diagnosis even more challenging.

OHA is encouraging providers to work closely with local public health authorities to ensure patients complete their treatment, and to facilitate the testing and treatment of people with whom the patients have had sexual contact. Singson said OHA is aligned with American College of Obstetricians and Gynecologists guidance in recommending that all pregnant people be universally screened at three timepoints during their pregnancy: their first prenatal visit, at 28 weeks, and at the time of delivery.

Addressing this crisis requires not only a concerted effort to educate providers and communities but also expanding screening, treatment and access to care.

“With coordinated action, increased awareness and commitment to equitable care, we can end this crisis and protect future generations of Oregonians,” said Singson.

Increasing awareness and education about primary prevention, public health risks and preventive health services are among actions OHA is taking as part of its 2024-2027 Strategic Plan. The plan further supports expanding access to vaccines and other health resources for children, parents and families in all communities in Oregon.

OHA Seeks Your Help To Make Health Care More Affordable -05/12/25

May 12, 2025

Media contact: Franny White, Franny.l.white@oha.oregon.gov, 971-349-3539

OHA seeks your help to make health care more affordable

New committees, public hearing provide opportunities to brainstorm solutions

SALEM, Ore. – Are you concerned about paying for a health emergency or routine care? Do you have an idea that could make health care more affordable? Oregon Health Authority (OHA) wants to hear from you.

“Everyone deserves quality health care, but growing medical costs make that increasingly challenging,” said Antonio Germann, M.D., a family physician who is vice-chair of the Oregon Health Policy Board, a citizen-led body that oversees OHA. “We need to tackle this complex issue to ensure our future health, and we’re inviting people to share their personal experiences and expertise with us to help us address it.”

About 83% of Oregon adults worry about being able to afford health care in the future, and 43% have struggled to pay their medical bills, according to a 2024 survey. Concerning statistics like this prompted OHA to make strengthening affordable health care for all a pillar in its strategic plan. It also led the Oregon Health Policy Board to seek the public’s help in identifying a broad range of solutions by serving on committees and participating in a June 10 public hearing.

Oregonians are invited to submit applications to serve on two new committees focused on health care affordability. May 16 is the extended deadline to apply for both committees. Applications and more information are available on the Committee on Health Care Affordability and Industry Advisory Committee webpages. Once their members are chosen, the committees plan to meet beginning this summer. Additional details are below.

The Committee on Health Care Affordability, also simply called the Affordability Committee, is seeking diverse voices. Its members may include people who receive health care, employers that purchase insurance, health economists and health policy experts.

The Affordability Committee will be supported by the Industry Advisory Committee, which also aims to include a variety of perspectives, ranging from health insurers to providers, hospitals and health industry leaders. Health care professionals in small or independent practices, and those who specialize in primary care, behavioral health, oral health or pediatrics are particularly encouraged to apply to the industry committee.

Comment at public forum

Both committees will build on the work of OHA’s Sustainable Health Care Cost Growth Target program, which seeks to limit Oregon’s health care cost increases to 3.4% per person annually. Between 2021 and 2022, the state’s health care spending grew by 3.6%, slightly more than the target.

Every year, the Health Care Cost Growth Target program holds a legislatively required public hearing to discuss recent trends in health care spending and highlight what’s driving health care cost growth. The 2025 public hearing will specifically explore behavioral health and pharmacy spending trends and will also focus on policy ideas to improve health care affordability. Information and potential solutions discussed at the event will help inform the new committees’ future work. People are also encouraged to share their personal stories and ideas about health care affordability during the hearing. See below for details on how to participate.

What: Health Care Cost Growth Public Hearing

When: 10 a.m.-Noon PT Tuesday, June 10, 2025

Details: Hybrid virtual and in-person meeting to discuss health care costs in Oregon, including recent trends, their causes and ideas for slowing cost growth.

Get involved: Consumers, clinicians and businesses are invited to share their concerns about and experiences with health care costs. Email written testimony or sign up to provide spoken comment at HealthCare.CostTarget@oha.oregon.gov.

Recreational Use Advisory Lifted For Emigrant Lake -05/09/25

May 9, 2025

Media contact: Erica Heartquist, 503-871-8843, PHD.Communications@oha.oregon.gov

Recreational use advisory lifted for Emigrant Lake

PORTLAND, Ore.—Oregon Health Authority (OHA) has lifted the recreational use health advisory issued for Emigrant in Jackson County.

OHA issued the advisory on May 1 due to the photo and satellite imagery evidence of potentially-toxin producing cyanobacteria near areas of high recreational use.

Water monitoring has confirmed that the level of cyanotoxins in Emigrant Lake are below recreational guideline values.

OHA advises recreational visitors to continually be alert to signs of cyanobacteria blooms. This is because blooms can shift quickly. They can develop and disappear on any water body at any time when bloom conditions are favorable. Some cyanobacteria move up and down in the water depending on light and nutrients, so what’s visible on the surface can change throughout the day. Wind and water movement can also affect where the bloom appears.

Only a fraction of water bodies in Oregon are monitored for blooms and toxins, so it’s important for people to become familiar with signs of a bloom, exposures and symptoms by visiting OHA’s Cyanobacteria (Harmful Algae) Blooms website at http://www.healthoregon.org/hab.

When recreating, people, and especially small children, and pets should avoid areas where the water is foamy, scummy, thick like paint, pea-green or blue-green, or if thick brownish-red mats are visible or bright green clumps are suspended in the water. If you see these signs, avoid activities that cause you to swallow water or inhale droplets, such as swimming or high-speed water activities, and keep pets out of the area.

Cyanotoxins can still exist in clear water. When a bloom dies, toxins released may reach into clear water around the bloom. Blooms can be pushed into other areas, leaving toxins behind. There also are species of cyanobacteria that anchor themselves at the bottom of a water body, live in the sediment, or can grow on aquatic plants and release toxins into clear water.

For health information or to report an illness, contact OHA at 971-673-0482, or visit OHA’s Cyanobacteria (Harmful Algae) Blooms website.

Recreational Use Advisory Issued For Wapato Marsh At Oaks Bottom Wildlife Refuge -05/02/25

May 1, 2025

Media contact: Erica Heartquist, 503-871-8843 PHD.Communications@oha.oregon.gov

Recreational use advisory issued for Wapato Marsh at Oaks Bottom Wildlife Refuge

PORTLAND, Ore.—Oregon Health Authority (OHA) issued a preemptive recreational use health advisory today for Wapato Marsh due to the presence of a cyanobacteria harmful algae bloom. The marsh is in Multnomah County.

OHA encourages people to visit Wapato Marsh and enjoy activities such as hiking, biking, picnicking and bird watching.

Drinking water

Drinking water directly from areas of the lake affected by a bloom is especially dangerous. Toxins cannot be removed by boiling, filtering or treating water with camping-style filters. Contact campground management or the local health department with questions about water available at nearby campgrounds or day use areas.

Not all private treatment systems are effective at removing cyanotoxins. People who do not use a well or public water system and draw in-home water directly from an affected area are advised to use an alternative water source.

Children and pets

Children and pets are at increased risk for exposure because of their size and level of activity. Dogs can get extremely ill and even die within minutes to hours of exposure to cyanotoxins by drinking the water, licking their fur, or eating the toxins from floating mats or dried crust along the shore. This is regardless of a recreational use health advisory in place.

Dogs can become ill and die from water intoxication after drinking excessive amounts of water while swimming or fetching objects for long periods of time. Intoxication is a potentially fatal disturbance in brain function resulting from an imbalance of electrolytes in the body. Water intoxication and heat stroke can cause similar symptoms as exposure to cyanotoxins.

Symptoms

Exposure to cyanotoxins can be serious and cause a range of symptoms. Symptoms may be similar to food poisoning such as stomach cramping, diarrhea, nausea and vomiting. Symptoms may also be more serious, such as numbness, tingling, dizziness and shortness of breath. These symptoms may require medical attention.

Dogs can experience weakness, difficulty walking, seizures, lethargy, loss of appetite and more. If a dog exhibits symptoms, veterinary treatment should be sought as quickly as possible.

Fishing

Fish caught from areas where cyanobacteria blooms are present may pose unknown health risks, so OHA recommends not eating fish from those areas. Those who decide to eat the fish should remove fat, skin and organs before cooking or freezing. Toxins are more likely to collect in these tissues. Fillets should also be rinsed with clean water.

For health information or to report an illness, contact OHA at 971-673-0482, or visit OHA’s Cyanobacteria (Harmful Algae) Blooms website.

Recreational Use Advisory Issued For Emigrant Lake -05/01/25

Media contact: Timothy Heider 971-599-0459 PHD.Communications@oha.oregon.gov

Recreational use advisory issued for Emigrant Lake

PORTLAND, Ore.—Oregon Health Authority (OHA) issued a preemptive recreational use health advisory today for Emigrant Lake, in Jackson County,  due to the presence of a cyanobacteria bloom.

People should avoid swimming and high-speed water activities, such as water skiing or power boating, in areas of the reservoir where blooms are present, as the major route of exposure is ingestion of water. Toxins are not absorbed through the skin. However, those with skin sensitivities may get a puffy red rash.

OHA encourages people to visit Emigrant Lake and enjoy activities such as fishing, camping, hiking, biking, picnicking, bird watching, canoeing, and kayaking.

Boating is safe as long as speeds do not create excessive water spray. Sprays could lead to the risk of inhaling cyanotoxins.

Drinking water

Drinking water directly from areas of the lake affected by a bloom is especially dangerous. Toxins cannot be removed by boiling, filtering or treating water with camping-style filters. Contact campground management or the local health department with questions about water available at nearby campgrounds or day use areas.
