CRISPR/Cas13 could be used as broad anti viral for RNA viruses: https://pmc.ncbi.nlm.nih.gov/articles/PMC7985958/ https://www.genengnews.com/gen-edge...iosciences-uses-crispr-to-target-rna-viruses/ Dr Hanson and Dr Chia support the theory of chronic enterovirus non cytolytic infection as the driving mechanism in MECFS. This potential treatment would be worthy of consideration/investment.
Pretty sure that's only retroviruses. This kind of idea's been around for a long time, but no one's produced any evidence for it.
