Following the results for the WK-521 strain, when EFE was added 2 h before infection at a concentration of 100 μg/mL, the log10 reductions in QK002 (alpha), QHN001 (alpha), TY7-501 (beta), TY7-503 (beta), TY8-612 (gamma), TY38-873 (omicron BA.1), and TY41-702 (omicron BA.5) virus titers in the culture supernatant at 24 h post-infection were 3.06, >5, >4.5, 4.25, >4.5, 2.25, and 2.04, respectively (Table 3, Figure 3A). The gene discussed is TAFAZZIN; the disease is infection.
