Smallpox is an infectious disease caused by the variola virus. The disease arrived in what is now Canada with French settlers in the early 17th century. Indigenous people had no immunity to smallpox, resulting in devastating infection and death rates. In 1768, arm-to-arm inoculation became more widely practised in North America. By 1800, advances in vaccination helped control the spread of smallpox. Public health efforts also reduced rates of infection.
