The claim posted on Tiktok that there is a “Patient with the Plague in Oregon” is true. This claim can be proved true through evidence posted by the Deschutes County Health Services, sited below, confirming a case of human plague. The "Deschutes County Health Services has confirmed a case of human plague in a local resident" on February 7th 2024, according to their website. The last reported case of the plague in Oregon was back in 2015(CDC). While the claim comes from a Tiktok post of an account by the username “@dailyfishtoknew”, which I'm typically very wary of, upon further personal research I was able to confirm this claim true. @Dailyfishtoknews has a strong following of over 180 thousand people, but they rarely credit where their information is from and the rest of their posts should be consumed with discernment. Website postings confirmed the infected person in Oregon was treated, and that according to health officials there is "little risk to the community" that the disease will spread. The plague is extremely rare to catch these days and much more treatable, but according to the CDC, an average of seven plague cases are reported a year. The case reported recently in Oregon is thought to have been caused by the person's symptomatic cat. The doctor who treated the patient, Dr. Richard Fawcett, confirmed that all close contacts of the resident and their cat have been informed and provided medication, luckily this case was caught very early.
