Anti-Influenza Virus Activity of Povidone-Iodine Products
Broad Killing Power Against H5, H7 and H9 Avian Influenza A Viruses with Nasal and Throat Sprays
By Peter A. McCullough, MD, MPH
A new outbreak of H7N9 avian influenza in the U.S., has been detected on a farm of 47,654 commercial broiler breeder chickens in Noxubee, Mississippi, March 13, 2025, as the Paris-based World Animal Health Organisation said in a report on Monday, citing U.S. Authorities.
H7N9 is thought to be considerably more deadly than H5N1. I wondered if standard-of-care nasal and throat sprays and gargles with dilute povidone iodine would continue to have protective effects.

Ito et al reported in in 2006:
The in vitro antiviral activity of PVP-I products (2% PVP-I solution, 0.5% PVP-I scrub, 0.25% PVP-I palm, 0.23% PVP-I gargle, 0.23% PVP-I throat spray and 2% PVP-I solution for animals) against avian influenza A viruses [a highly pathogenic avian influenza virus, A/crow/Kyoto/T2/04 (H5N1; 106.5 EID50/0.1 ml), and 3 low pathogenic avian influenza A viruses, A/whistling swan/Shimane/499/838 (H5N3; 104.8 EID50/0.1 ml), A/whistling swan/Shimane/42/80 (H7N7; 105.5 EID50/0.1 ml) and A/duck/Hokkaido/26/99 (H9N2; 104.8 EID50/0.1 ml)] were investigated using embryonated hen’s eggs. Results/Discussion: Viral infectious titers were reduced to levels below the detection limits by incubation for only 10 s with the PVP-I products used in this study. These results indicate that PVP-I products have virucidal activity against avian influenza A viruses. Therefore, the PVP-I products are useful in the prevention and control of human infection by avian influenza A viruses.
Thus a 10 second exposure in the nose and mouth effectively killed H7NX and similar strains giving us reassurance our approach is on track. The main public health task now is getting the iodine-based sprays and gargles to the workers and ensuring they are following a twice daily and post exposure (eg culling) schedule. If severe disease develops we reiterate our guidance for immediate oral oseltamivir while waiting for the PCR test result. The best way to prevent serious cases of bird flu is to share this article and telling poultry and cattle workers about the free Wellness Company Prevent and Protect Program.

I am curious about the validity of the PCR test that is being used to detect the influenza virus. We know how PCR testing was abused in the case of SARS-CoV2--how excessive cycles were used to "find" the virus, even in asymptomatic people. And how the inventor of the PCR test, Kerry Mullis, was explicit that it should not be used as a diagnostic tool--that it was not suitable for that purpose. So, what is going on with these PCR tests for influenza? How are they being administered? How many cycles are used to get "results"? How do we know that they are of any validity in this context?
It's been a couple of years ago now when Dr. Peter McCullough first told us about the 1% iodine "Kill it in your face" technique for any cold, flu, COVID, or WHATEVER virus that comes around. Since then, any time I've caught something, the iodine nasal flush and gargle every 5 hours has cut the misery and duration to a fraction of what others are experiencing. It makes it a cakewalk by comparison.
I carry the 1% diluted iodine in my car, stocked up on $6 bottles of the 10% providone iodine for perpetuity and educate about this treatment everywhere I go.
There is no need to test to identify what the pathogen is. In our world and all worlds, there is only the need for the communication, strengthening and preservation of Knowledge.
