Those findings are consistent with a recent report from South Africa, which has not yet been reviewed by experts. The reported impact of nasal sprays on COVID-19 outcomes is promising, but a randomized clinical trial is necessary to definitely say that this approach is safe and effective for widespread use. It's not a decongestant but a corticosteroid spray -- fancy talk for a steroid spray that has almost no absorption beyond the nose but that reduces the nasal inflammation that comes with so-called allergic rhinitis.

While well have to wait to see if the science bears out, that might be an indicator that thats where the virus is growing first, said Gigi Gronvall, an immunologist and testing expert at Johns Hopkins Bloomberg School of Public Health.
