However, based on the studys findings and the fact that ACE2 expression is highest in the nasal mucosa, it can be hypothesized that by suppressing viral load and receptor expression in the nose, intranasal corticosteroids use can be effective against severe disease. The study comes a week after the Food and Drug Administration released its own update on the effectiveness of the rapid antigen tests. A small, new real-world study suggests that two widely used at-home antigen tests, the Abbott BinaxNOW and Quidel QuickVue, may fail to detect some Omicron infections even when people are carrying high levels of the coronavirus. tests, which have proven popular for screening students in schools.
