It’s ironic that this article is telling people to seek advice with trusted medical providers when many doctors don’t understand anything about long covid and they and their staff aren’t even wearing masks.

This is a good point, sadly! Before the pandemic "consult with doctors" always made sense but I think most doctors would advise us to unmask and ignore the pandemic entirely. I read recently that it takes 17 years for medical research to be incorporated into clinical advice. Doesn't mean that nasal sprays do all they're advertised as doing but I feel like the era of doctors as the final arbiters of good science is over.

I understand your concern. These product aren’t being used blindly. Each has at least one peer reviewed study in a reputable journal showing some efficacy. The FDA has also dragged their feet in evaluating these products.

Could you please address the efficacy of saline sinus irrigation after potential exposure?

Thanks very much.

There have been a few publications, but not enough to rely on for post-exposure prophylaxis. Sterile saline if used appropriately can be helpful for relief of some symptoms as described above, and is not likely to be harmful if used appropriately. https://www.cdc.gov/parasites/naegleria/sinus-rinsing.html

You sound like a pro-covid shill.

Swiss cheese approach always but one thing I will say about this illustration is that it doesn't seem to take into account that mucous circulates antivirals through a wider area than the topical zone. That's how mucosal vaccines are intended to work, right?
