Did you know that there are viruses that spread faster than the common cold? The human body is a delicate ecosystem, and when one thing gets out of balance, it can throw the whole thing into chaos. That’s where viruses come in. These tiny little invaders are made up of just a few cells—but they’re so good at spreading that they can infect entire populations in short order.
Here are some of the fastest-spreading viruses in human history: Those that have spread the farthest and quickest (by number of cases)
While it’s not necessarily the scariest virus on this list, influenza (a.k.a. the flu) is certainly one of the most dangerous and most common viruses known to man. In fact, there are over 200 subtypes of influenza that have been identified over the years the flu can affect humans, birds, pigs and horses —making it one hardy little bugger that refuses to go away no matter how many vaccines we create against it. The worst pandemic in history was caused by a genetic mutation called H1N1 in 1918 which killed between 50 and 100 million people worldwide (and possibly up to 500 million people if you include some estimates). It took off so quickly because people weren’t aware of what they were dealing with; many thought they had just caught a cold or a bad case of diarrhea until their lungs started shutting down as well as their bodies filled with fluid from internal bleeding due to ruptured organs.”
This was an interesting exercise, but it doesn’t mean that we should be worried about these viruses. Many of them are very old or only infect other animals. In fact, the most recent one is from 1997 and would not be considered a serious threat to human health today because of our understanding of vaccines and medical treatment. The lesson here is that viruses always have been with us and will continue to be part of life on Earth for as long as there have been people living there – so don’t fret too much when you get colds or flu season comes around again!
