Smallpox has existed for thousands of years, causing devastating epidemics throughout human history. Edward Jenner developed the first effective vaccine against smallpox in 1796, laying the foundation for modern vaccinology. Through a massive global vaccination effort led by the World Health Organization (WHO), smallpox was officially declared eradicated worldwide in 1980, making it the first human disease to be eliminated.
Smallpox primarily spread from person to person through prolonged, direct face-to-face contact via respiratory droplets from an infected individual's coughs or sneezes. It could also spread through direct contact with infected skin lesions or scabs, and less commonly, via contaminated materials like bedding and clothing.
