One of the deadliest pandemics, the "Spanish Flu", killed off what percentage of the human world population at the time?

The Spanish flu, which occurred from 1918 to 1919, is considered one of the deadliest pandemics in human history. It is estimated to have killed off approximately 3 to 6 percent of the global population at that time. The pandemic spread quickly, taking advantage of the post-World War I conditions, and infected millions of people worldwide. Despite its name, the origins of the Spanish flu remain uncertain, but its rapid and extensive spread, coupled with the lack of medical advancements and strategies to combat the virus at the time, led to a high mortality rate. The virus disproportionately affected young adults, which might explain its higher mortality rate compared to other flu outbreaks. The devastating impact of the Spanish flu highlights the vital importance of preventative measures, early detection, and effective healthcare systems in addressing pandemics.
