Responding to extreme heat conditions during the COVID-19 pandemic could place many vulnerable populations at further risk during the warm summer months when many people leave their houses to escape the heat and visit cooling centers and other public spaces. People's vulnerability is likely to vary over time and space, shifting with the extent of exposure to extreme heat, differences in policy and community response, and disease pressure from COVID-19.
