Infectious Disease Risks and Vulnerabilities in the Aftermath of an Environmental Disaster in Minas Gerais, Brazil

In January 2019, the state of Minas Gerais experienced another environmental disaster with the collapse of a mining dam near the city of Brumadinho. This disaster has resulted in 256 deaths and 14 people still missing. Toxic mud has contaminated the Paraopeba River resulting in significant fish and wildlife deaths in the river and surrounding areas. The effect of environmental disasters such as this is felt across multiple sectors damaging ecosystems in agriculture, wildlife and human communities. Environmental disasters cause significant disruption of ecosystems, flooding, contamination of water supplies, and displacement of human populations, which can result in increases in transmission and outbreaks of mosquito-borne and zoonotic diseases that can become a serious and long-term public health problem for the region.
