💨 Abstract

Throughout history, viruses like Ebola, COVID-19, and HIV have caused widespread impact and fatalities. Over 600 viruses can infect humans, with varying severity and mortality rates. Technological advances and public health efforts have mitigated the impact of many viruses, such as smallpox, which was eradicated through vaccination. Measuring virus severity involves considering mortality rates and transmission ease.
