so, you've listed an yahoo "article", that is ctrl c ctrl v of two other "articles" published on sites that will post everything you want if you pay them, both also linking an article from "scientific" "peer-reviewed" "journal" prominently appearing in Beall's list beallslist.net (usually called list of predatory journals in less polite company) that operate under the same business model but this time adding veneer of scientific credibility. i'd also note that Robert Beatty is not affiliated with any university, instead his only affiliation is Beatty LLC, listed under "allopathic and osteopathic" practitioner https://npidb.org/doctors/allopathic_osteopathic_physicians/neurological-surgery_207t00000x/1447264122.aspx

this is on background of acyclovir being trialed for covid, and nothing has come out of it. taken together none of this passes smell test, however this fits alternative medicine narrative like a glove: outsider doctor shows that treatment was there all along and it's cheap and he'll sell it to you, because it's not drugs that treat people, it's knowledge that the medical establishment supresses

you've just helped spreading medical disinformation

A report of 4 patients is hardly called a "study" and even less a "cure". Anti-viral drugs may have their application in long-covid cases, but usually the side-effects outweigh the benefits.

Also the author claims in the summary:

This study presents a novel theory of sequestered COVID-19 virus in the body.

That is quite a stretch to get to from these 4 subjective reports. Neither is it novel, nor is there solid evidence in the reports.
