OHA reports 3 humans with bird flu traveled to Oregon during Washington outbreak.

PORTLAND, Ore. (KOIN) – A week after Washington reported human cases of bird flu in the state, officials have announced that three of those cases had traveled to Oregon during their infection and were monitored during their stay.

All three cases of highly pathogenic avian influenza (HPAI) were reported in Washington after they were exposed to poultry that tested positive for the virus on Oct. 15. As of Thursday, Oct. 31, there have been nine total cases in Washington — including those who had traveled to Oregon.

Oregon Health Authority officials say the cases have returned to Washington and will continue to be monitored by Washington health staff until 10 days following their last exposure.

“At this time, the risk for the general public remains low,” Dr. Melissa Sutton with Oregon Public Health said in a statement. “People who have had close or prolonged, unprotected exposures to infected birds or other animals, or to environments contaminated by infected birds or other animals, are at increased risk of infection.”

Washington Department of Health announced another bird flu case that led to 800,000 euthanized birds in Franklin County after they all tested positive on Oct. 15. Another case was recorded at a Clackamas County commercial poultry farm, and those birds were also euthanized to limit the spread of the disease.

It is not clear which Clackamas County poultry facility was impacted in this case, but the ODA said the operation consisted of 150,000 birds.
