That's a great question. In 2003 we had SARS, then around 2014 MERS, 2020 Covid. All the same virus. The virus morphs, and affects us differently. That is what a virus does. It morphs. Yes actually as earlly as 2011 a reslient form of gonorrhea was picked up, and later in 2017 Zithro was dropped as an effective method of treating a new form of gonorrhea. The purpose of my post was to point out that the newest form is proving to be harder to cure and in some reported cases, mostly third world countries, non curable.
It was meant to be taken as a possible deterrant to BBFS. A virus morphs, and old information may no longer be pertinent nor applicable to newer stronger more aggressive froms.
Can you see where with all the BBFS going in how it is a bredding ground for stronger forms? That is how it happens with every virus. Also antibiotics used on the person over and over for the same disease become less effective.
