![]() ![]() Peter Graven, Lead Data Scientist, Oregon Health & Science University Mariana Robins, a 15-year old with long-haul COVID-19 symptoms. Vaccinating Oregon: Beginning with the availability of vaccines, OHSU partnered with major Portland-area health systems to administer nearly 900,000 doses at mass vaccination sites including the Oregon Convention Center, the economy parking lot at Portland International Airport, and other drive-through sites at Hillsboro Stadium, the Portland Expo Center and OHSU’s Marquam Hill campus.On April 30, Governor Kate Brown gave an update on the status of COVID-19 in Oregon. ![]() Testing people: In March of 2020, OHSU started a mobile testing program that provided free COVID-19 tests for thousands of people every week - most of whom are not OHSU patients. ![]() Tracking variants: Leaders in OHSU’s research and clinical missions joined together to conduct genome sequencing and track the spread of virus variants across the region, producing a weekly report for the Oregon Health Authority.In addition to Graven’s statewide forecasts, OHSU’s public health initiatives include the following: “It looks like herd immunity was reached in local transmission networks that supported omicron transmission, but it will not necessarily remain high enough to prevent future surges, as new variants evade current immunity - and immunity wanes over time.” OHSU takes on public health role in pandemic responseĪs Oregon’s academic health center, OHSU reached beyond its traditional missions to take on a public health role throughout the pandemic - tracking, testing, treating and preventing the spread of the SARS-CoV-2 virus. “Like politics, all disease transmission is local,” Messer said. The rapid decline in cases and hospitalizations in Oregon likely reflects that the omicron variant raced through the population quickly, leaving an ever-shrinking pool of people susceptible to severe illness.Įven though immunity is generally thought to be high right now, COVID-19 will continue to present a threat in the months and years to come, said Bill Messer, M.D., Ph.D., associate professor of molecular microbiology and immunology, and medicine (infectious diseases) in the OHSU School of Medicine. “Now we’re into the surveillance mode,” Graven said. Forecasting will become increasingly complex, with unknowns around the duration of immunity and the ability of new variants to generate surges in severe illness that are large enough to overwhelm hospital capacity. Graven will monitor reporting around new cases, emerging variants and indications of breakthrough cases that cause illness severe enough to land people in the hospital. Today will be the last weekly news summary, absent the emergence of a new wave of severe illness that threatens to overwhelm Oregon hospitals in the weeks and months ahead. The next expected forecast will be issued the week ending Friday, March 25. Graven will continue to produce regular forecasts every other week, available on OHSU's website. With hospitalizations and cases receding, the state will lift its indoor mask requirement at 11:59 p.m. And we need to remember that COVID-19 will continue to present a threat to people who are immunocompromised, older adults and those with underlying health conditions.” “The risk right now is quite low for most healthy people in Oregon. ![]() “It’s fair to say the omicron surge is behind us, though COVID is not,” said Peter Graven, Ph.D., director of the OHSU Office of Advanced Analytics. ![]()
