T cells therefore act where neutralizing antibodies may have failed, after infection. It's still early and there are a lot of unknowns about XBB.1.5, he said. For cases in which multiple samples were collected in each time segment, we used the sample with the highest amount of viral RNA (i.e., lowest Cq values) in each time segment for each case for comparison. data from the Centers for Disease Control and Prevention, Why doctors struggle to identify treatments for long COVID. "We might be learning that the time of incubation might be a little shorter. The CDC also notes, however, that if you have access to antigen tests, "you should consider using them. We measured Cq values (i.e., viral RNA levels) by using qRT-PCR targeting the SARS-CoV-2 nucleocapsid gene (Appendix Figure 1).
