To cure COVID-19, we propounded mopping viruses/infected cells by opposite-charges electrostatic attraction as mechanism of treatment. RNA viruses (including COVID-19 virus) are positively charged while DNA viruses and abnormal (infected/tumor) cells are negatively charged but normal cells are neutral. Molecules of Aluminum-magnesium silicate (AMS), a WHO-approved medicine, consist of Nanoparticles that have both negatively and positively charged ends. Ultra-small size (0.96 nm thick) of the Nanoparticles, allows them access to cells in all organs. Nigeria does not have natural AMS-deposits but she has Aluminum silicate and Magnesium silicate, abundantly. These solid minerals which are WHO-approved medicines too were used to formulate an AMS-brand, named, Medicinal synthetic AMS (MSAMS, VITUMED ® , Antivirt ® ). Dextrose monohydrate (simple sugar) is incorporated in each MSAMS-formulation to convey the electrically charged Nanoparticles across mucous membranes (active-transportation) into blood for circulation to all organs. The Antivirt ® has proved effective against all viral and abnormal-cell diseases so far tested including COVID-19.
