Some of the deadliest pandemics in human history changed the world forever. 🦠🌍 From the Black De@th, which may have killed up to 200 million people, to the 1918 Spanish Flu and the ongoing H!V/A!DS pandemic, infectious diseases have repeatedly reshaped populations, economies and healthcare systems. What makes these numbers even more striking is that many of these outbreaks happened before modern medicine, vaccines and advanced public-health systems existed. History shows just how devastating a pandemic can become—and how important scientific research, prevention and preparedness are. 🧬📊 De@th tolls are historical estimates and vary significantly by source.
