The 1887 Yellow River flood was a devastating flood on the Yellow River (Huang He) in China. This river is prone to flooding due to the elevated nature of the river, running between dikes above the broad plains surrounding it. The flood, which began in September 1887, killed at least 900,000 people. The highest estimated death toll is 2,000,000. It was one of the deadliest natural disasters ever recorded. This flood is ranked one of the top most dangerous natural disasters ever.

The history of smallpox in Mexico spans approximately 500 years from the arrival of the Spanish to the official eradication in 1951. It was brought to Mexico by those in Spanish ships, then spread to the center of Mexico, where it became a significant factor in the fall of Tenochtitlan. During the colonial period, there were major epidemic outbreaks which led to the implementation of sanitary and preventive policy. The introduction of smallpox vaccination in New Spain by Francisco Javier de Balmis and the work of Ignacio Bartolache reduced the mortality and morbidity of the disease.
