Help fight COVID-19: CDC must issue guidance on nasal sprays
0 have signed. Let’s get to 1,000!
Doctors, nurses and other public health professionals are petitioning the Centers for Disease Control to issue Guidance calling on: Americans to use nasal sprays to combat the COVID-19 pandemic; and doctors to use them in treating COVID-19 patients. Help them, lend your voice to the effort.
Why: We face a raging pandemic. And, now there is a new, worse strain. While we all hope for a safe and effective vaccine, at best it will be months before enough Americans are vaccinated to stop the pandemic. We have to use every tool at our disposal to help protect ourselves, our families, our loved ones, our communities and our nation.
Why nasal sprays: Scientific studies now show nasal sprays can help protect you from getting sick and reduce the risk of transmission:
- There are scores of studies showing nasal sprays wash pathogens from your nose--just like hand washing only better for respiratory infections like COVID-19.
See, e.g., Casale, Manual, et al., Could nasal irrigation and oral rinse reduce the risk for COVID-19 infection?, Int J. Immunopathol Pharmacol. 2020 Jan-Dec; 34: 2058738420941757, available at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7436790/
- There is new data that some nasal sprays are anti-viral (they block COVID-19 infections in the nose) and virucidal (they actually kill and/or deactivate the virus)--meaning they protect you from getting sick.

- There is a new study out of Columbia Univ. showing nasal sprays prevented COVID-19 infections in animals (which is how we initially test medical drugs and devices) exposed to the disease.

- There is a new study that one such spray, Xlear, helped lessen the severity of COVID-19 and shortened the time of sickness for people who were already sick and had co-morbidities.

- Nasal sprays like these have been sold in the US for over two decades and been used by millions of people around the world--without any adverse reports.
- Nasal sprays like these are available at your local store. They are cheap, safe, noninvasive, easy to use.
Nasal sprays should be a layer in protecting yourself and others from COVID-19. You should still wear a mask, social distance, wash your hands, avoid crowds and follow public health guidelines, but nose sprays add one more layer of protection to keep you and your family safe.
If more Americans used nasal sprays, we could reduce the transmission of the virus, save lives and get back to normalcy faster.
If more doctors treated COVID-19 patients with nasal sprays, the data indicates we could save lots more lives.
CDC should issue commonsense guidance calling on Americans to use nasal sprays and doctors to add them to how they treat COVID-19 patients.
