PURPOSE: The objective was to assess the efficacy of seawater nasal wash on symptom duration, intranasal viral load, household transmission in COVID-19 and URTIs. METHODS: This prospective, randomized, controlled, multicentric, parallel study included 355 mild/moderate COVID-19 and URTI adults with rhinologic symptoms /= 1.5log10 copies/10000 cells at Day 5: 88.9% vs 62.5%, p = 0.0456). In the active group, a lower percentage of SARS-CoV-2 positive household contacts (0-10.7%) was reported vs controls (3.2-16.1%) among subjects with Delta variant (p = 0.0413). CONCLUSION: This trial showed the efficacy and safety of seawater nasal wash in COVID-19 and URTIs. TRIAL REGISTRATION: Trial registry ClinicalTrials.gov: NCT04916639. Registration date: 04.06.2021.

1. Nasal spray is the easiest way to go in preventing Covid

There’s a spray called Xlear that’s great. I was checking out the research back in ‘20 and at that time it looked like sprays containing seaweed or grapefruit extracts or xylitol were protective… now there’s research showing they significantly reduce viral load once a person has symptoms, too. I started looking because of the research at that time showing that the nose is where Covid sets up shop and starts building before symptoms show up in the rest of the body. I found a spray called “Xlear” and we’ve been using it for a few days whenever we’ve potentially been exposed.

Such a simple and effective strategy, yet the info gets so little public dissemination.

Thanks for posting this, Grasswire!
