The US Government Comparative Toxicogenomics database shows that Fluoride can inhibit Human immunity to viruses and pneumonia. Angiotensin I-Converting Enzyme (ACE), 2'-5'-Oligoadenylate Synthetase 1 (OAS1) and Intercellular Adhesion Molecule 1 (ICAM1) are included as susceptible epigenetic targets of the poison.
Wuhan is an area with high Fluoride exposure from atmospheric and groundwater pollution.
Are there more studies linking virus outbreaks or mutations with Fluoride?
