![]() Merchak said the initiative's "well-oiled machine" has been preparing for manual experiments to validate whether home COVID tests are less sensitive to EG.5 and other variants, in case the FDA decides to call for home COVID tests to be rechecked for the new strains. We can do computational analytics to see whether or not we think there's going to be any impact on test performance," Todd Merchak, co-lead of the NIH's RADx Tech initiative at the National Institute of Biomedical Imaging and Bioengineering. We also have the epitopes mapped for all antigen-based tests. "Now we have the genome mapped and all that information. One positive development - Modeling suggests the variant will not evade tests better than other previous Omicron strains. The Food and Drug Administration has so far not flagged any new issues with the EG.5 and FL.1.5.1 variants, from its ongoing joint effort with the National Institutes of Health to study the performance of COVID-19 tests with new strains. They seem to work, although that may change if one of the strains becomes more prevalent. Do COVID tests work for new COVID variants? ![]() said its BA.2.86 case was tested at a London hospital, but that it was currently not possible "to assess comparative severity by variant" based on their data. ![]() In Denmark, health officials said their three BA.2.86 variant cases did not have "symptoms other than those normally seen" from COVID-19. The sole case in Michigan was "an older adult with mild symptoms, and has not been hospitalized," Chelsea Wuth, a spokesperson for the state Department of Health and Human Services, said in a statement to CBS News. As for BA.2.86, officials say it is too early to say whether that strain will cause more severe illness because of its worrying sum of mutations.
