The Legacy of Dr. John Snow

The video explores the life and work of Dr. John Snow, a 19th-century physician who played a crucial role in combating cholera outbreaks in London. Despite initial skepticism, Snow's innovative methods, including mapping cholera cases, laid the groundwork for modern epidemiology. His work demonstrated that cholera was waterborne, challenging the prevailing miasma theory. Although not recognized in his lifetime, Snow's contributions have saved millions of lives and continue to influence public health strategies today.
