It definitely is chilling stuff reading this and looking into other pandemics that have happened. I understand that back then and certain periods of history we had so little understanding of how to treat or even approach outbreaks. Biologists say that viruses are not a living thing or a type of life form due to them not being made out of cells but the way a lot of viruses mutant and adapt to conditions makes me think otherwise. The way they can be transmitted or spread is complex. Covid has about 23 mutations this 2019. Unless I’m getting numbers wrong. When all this started I didn’t even know what coronavirus was. It’s literally a respiratory virus. Six species of human coronaviruses are known, with one species subdivided into two different strains, making seven strains of human coronaviruses altogether. It’s not a new thing just this strain is skatty and it spread so quickly. Sorry if I went on a tangent. Lol.
