A laboratory study revealed that swabbing the Corona Virus with iodine for 15 seconds killed it. This is a proof that antiseptics or iodine can kill the virus on external surfaces. This also implies that washing the nose can be used as preventive measures against the virus.

It was discovered that swabbing the virus with iodine completely kills it after samples of the coronavirus were examined against three concentrations of iodine solution antiseptic.

The solution made the virus fully dormant after 15 seconds, even at 0.5% concentration.

This researchers, a team from the University of Connecticut School of Medicine added three different concentrations of the antiseptic povidone-iodine (PVP-I) solution on a sample of the virus.

And it was discovered that the lowest concentration of 0.5 percent made the SARS-CoV-2 dormant in as little as 15 seconds.

The researchers,then asserted that the rinses could curb person-to-person spread of the virus and a severe case by reducing the quantity of virus that moves down to the lungs.

It is a known fact that the nose encloses high levels of the receptor ACE-2, a channel with which the virus enters and infect human cells.

Due to this, various clinical studies have been carried out, and were centered on on nasal irrigations and washes as a way to limit the spread of the virus

Prior research has revealed that PVP-I has been useful in terms of inactivating pathogens linked to the new virus and that includes Severe Acute Respiratory Syndrome and Middle East Respiratory Syndrome.

For the research, published in JAMA Otolaryngology–Head & Neck Surgery, the team experimented samples of the virus against solutions using PVP-I as the main active ingredient.

The solution was then diluted at three different concentrations, 0.5 percent, 1.25 percent, and 2.5 percent.

PVP-I concentrations were then examined in regard with a 70 percent ethanol solution and inspected for reactions after 15 seconds and 30 seconds.

All the iodine concentration made the virus dormant in 15 seconds.

But the control experiment carried out using ethanol could not kill SARS-CoV-2 in the same time span.

‘Widespread use of PVP-I nasal antiseptic in patients prior to intranasal procedures could significantly decrease risk of virus transmission via droplet and aerosol spread.’ noted the researchers.

The researchers also said that clinicians could inform patients to wash their noses with PVP-I prior to appointments or procedures to prevent spread in waiting rooms or other common areas.

‘Povidone-iodine nasal irrigation may be beneficial for the population at large as an adjunct to mask usage as a means of virus mitigation,’ the authors wrote.

It is however not advisable to be done without the instructions or supervision of a clinician.
