WHO recipes for disinfectants have proven effective

Due to the general scarcity of disinfectant solutions that are effective against the coronavirus SARS-CoV-2, the federal government relaxed the regulations for the manufacture of disinfectants. Alcohol manufacturers are now allowed to provide alcohol from which pharmacies can then produce the funds themselves. Two mixtures recommended by the WHO were found to be effective against SARS-CoV-2 in a recent study.

Researchers at the Ruhr University Bochum (RUB) have confirmed the effectiveness of the disinfectants proposed by the World Health Organization (WHO) to kill SARS-CoV-2 viruses. Pharmacies are allowed to manufacture one of these prescriptions themselves. The results were recently presented in the "Emerging Infectious Diseases" journal of the American health agency Centers for Disease Control and Prevention (CDC).

Alcohol-based disinfectants kill SARS-CoV-2

The WHO recommends two recipes for the production of disinfectant solutions that are supposed to be effective against SARS-CoV-2. A recent study by the RUB confirms this. When used correctly, the alcohol-based agents are effective against the novel corona virus.

An international research team led by Professor Dr. Stephanie Pfänder from the Department of Molecular and Medical Virology at the RUB showed that SARS-CoV-2 viruses are sufficiently inactivated when they are exposed to the disinfectant solutions recommended by the WHO for 30 seconds. The effect is based primarily on the main components ethanol or isopropanol - both are alcohols.

Pharmacies may only implement one prescription

According to the temporary pharmaceutical law, pharmacies are currently allowed to manufacture isopropanol-based disinfectants themselves until August 2020. This means that pharmacies can only implement one of the two recommended WHO prescriptions.

The recommended recipes from the WHO

According to the WHO recommendation, the isopropanol solution should consist of 75 percent by volume of isopropanol, 1.45 percent by volume of glycerin and 0.125 percent by volume of hydrogen peroxide. The second recommended recipe (which pharmacies are not allowed to manufacture) should contain 80 volume percent ethanol, 1.45 volume percent glycerol and 0.125 volume percent hydrogen peroxide.

    Absolutely, he's not right

    On your place I would try to solve this problem itself.
