EUGENE, Ore.-- Health officials announced that they have identified four new presumptive positive coronavirus cases in residents living in Jackson, Klamath and Washington counties.
Among those cases, three were travel-related and one had contact with an already known case.
This makes seven total cases in Oregon confirmed by the Oregon Health Authority, the other three being identified in Umatilla and Washington Counties since Feb. 28.
Two of those new cases were detected in Jackson County, according to Jackson County Public Health. They are both adults between the ages of 55 and 74, "have known travel-related exposure," and are in a single household. They did not require hospitalization and have been isolated at home.
Dr. Jim Shames is the medical director for Jackson County and he said there is no threat to the community.
"The individuals have been fully cooperative with Jackson County and we don't feel there's any identifiable risk to the greater community in Jackson County and there are no known community spread at this time," he said.
The case in Klamath County was also travel-related. The case in Washington County had contact with an already known case and did not need medical attention.
Dr. Wendy Warren works for Klamath County Public Health and she said they have procedures as well to prevent the spread of the virus.
"There were a number of plans and procedures put in place. We did things that limited the spread to the community that were very effective so we are refining those and updating those as we go along," she said.
RELATED: OREGON SEES THIRD CORONAVIRUS CASE
According to the Oregon Health Authority, officials are working to reach out to people who were in close contact with the individuals tested as presumptively positive.
A presumptive case means that someone has tested positive at an in-state lab using CDC test kits, but still has to be confirmed by the CDC's own labs.
Officials said that on Friday, the Oregon State Public Health Laboratory tested 42 samples from 22 people, yielding the four presumptive positives and 18 negative results.
Health officials identified the third presumptive case, a person from Umatilla County, on Monday. They were being treated at a hospital in Walla Walla, Washington, while authorities worked to track down other people who may have been in close contact. The patient spent time at a youth basketball game in Weston, as well as Wildhorse Resort & Casino in Pendleton.
The earlier two cases were people in Washington County, Oregon, who had been in close contact with one another. The first case — now confirmed by the CDC — worked at an elementary school in Lake Oswego, prompting the school to shut down for thorough disinfecting.
