The results of a domestic in vitro cell test (in vitro) showed that'povidone-iodine', a well-known ingredient as'red drug', is effective in combating the Corona 19 virus.

Professor Man-Sung Park of the Viral Disease Research Institute of Korea University School of Medicine announced the results of evaluating the antiviral effect by applying a drug containing 0.45% povidone iodine to a corona 19 virus culture test tube on the 7th.

Researchers have confirmed that this drug reduces the Corona 19 virus by 99.99% and has an excellent virus killing effect.

Povidone-iodine has also been shown to be effective in combating influenza virus and acute respiratory syndrome (SARS) virus in previous studies.

The research team said, "Active hygiene management of the oral cavity, nasal cavity, and throat using povidone-iodine will be of great help in managing COVID-19 infection."

However, that does not mean that you should not dilute the'red medicine' and put it in your mouth or apply it to your nose to treat COVID-19.

Povidone-iodine drugs released for the throat should be used for the respiratory system.

The research results were published in the September issue of the'Journal of Bacteriology and Virology'.
