The dogs detected COVID with a sensitivity of 92% (which refers to their ability to correctly identify those with infection) and a specificity of 91% (their ability to correctly identify those without infection).
A subvariant of omicron responsible for a wave of new COVID-19 cases in parts of Europe and Asia is also gradually spreading in the United States, including in Washington state.
The United States could substantially reduce cancer deaths by closing gaps in its cancer screening programs, a presidential advisory group has concluded in a new report.
Rapid antigen tests can be ordered and shipped directly to Washington households at no-cost.
Beginning today, Washington state residents will be able to visit www.sayyescovidhometest.org to order rapid-antigen COVID tests online, and will receive those tests delivered at no cost.
There are just so many variables. Testing may come either too soon, before enough virus is present to detect, or too late, after a person has already spread the virus to others. And most rapid tests, even according to their instructions, are meant to be used in pairs — generally a day or two apart — for increased accuracy. Despite that, a few brands are sold one to a box and, with the tests sometimes expensive and in short supply, families are often relying on a single screening.
Anyone with any signs or symptoms of COVID-19 or known exposures should get tested, regardless of vaccination status or prior infection.
Planning to get together with family and friends? Whether you’re traveling or hosting, you should consider adding at-home COVID-19 tests to your checklist.
Covid antigen tests are easy to use and provide results quickly, typically within about 15 minutes.
Lab escape theories cannot clearly account for a virus that has evolved for human-to-human transmissibility.
Rapid antigen testing makes it much easier to get tested for COVID-19, which helps detect infectious cases before they spread. But many people are still unsure of how best to use these tests and whether they are accurate enough to be useful.
Of all women’s cancers, ovarian cancer has the lowest survival rate
Reputable COVID-19 testing options are available across the county, which provide free testing with rapid and highly accurate results.
The drop could hamper epidemiologists’ ability to spot and stem new surges of the deadly infection.
Many genetic findings are ambiguous, leaving doctors uncertain about whether a particular variant is truly dangerous.
