Lots of things have made people sick over many decades that were falsely attributed to viruses. It is not just one thing.

Polio was caused by toxins that were used in pesticides and in cities. First, it was lead arsenic, and then that was replaced with DDT. Once DDT was outlawed, polio went away. However, polio still exists in some parts of Africa where DDT is still used.

Chicken Pox is likely a detoxing process of maturity, similar to baby teeth falling out, the onset of puberty, etc.

Common cold/flu is a detoxing process that most people go through from time to time (due to poor nutrition and other external toxins). Happens primarily at different times of the year in different parts of the world, which would not be the case if it was a virus floating around when we have modern world travel.

This detox generally occurs during OCT-MAR in the Northern Hemisphere, during APR-SEP in the Southern Hemisphere, and during the rainy season in the tropics. What do all of these have in common? It is the time of year with the least amount of sunshine, and lowest levels of Vitamin D, which may be the trigger for the body to cleanse itself (to the extent it can, in our modern, unhealthy world).

Some people are so unhealthy, due to their lifestyle or other poisons in our world, that their body cannot cope and they die. This is rare in terms of numbers, but happens with unhealthy old people mostly.

HIV is a scam. The entire thing is fake, and created to make money (and to some extent, to discourge unmarried sex).

Covid is the exact same scam as HIV. Anyone who was sick had a cold, flu, or similar sickness. Most of the people are claimed to have "died of Covid" were sickly people -- obese, unhealthy people, and especially old people in nursing homes (as happens every "cold and flu season" every year).

It was created and perpetuated for several reasons, but the main reason was probably (IMO) to deceive people into believing they needed to take an injection of a mystery drug multiple times per year for the rest of their lives. The question is not is what is in these drugs? The question is: What are they planning to put into these mystery drugs in the future? First, you get people to believe they should take them forever. Then, you fuck around with what you put in them.
