Extreme heat is linked to pregnancy complications, including stillbirths and miscarriages — and the risk is growing

Our warming planet is putting those who are pregnant at higher risk — and the impacts go far beyond heat-related illnesses. Research shows that along with the dangers presented to the general population, extreme heat puts pregnant people — and their unborn fetuses — at risk of life-threatening conditions. 

During pregnancy, expectant moms are are more vulnerable to viruses and environmental conditions. And one of the threats comes from tiny insects: mosquitoes that can carry a handful of diseases. 

Some of those diseases, like West Nile and eastern equine encephalitis (EEE) are rare but serious and can be deadly for the general population. Others, primarily found in tropical climates, like Oropouche virus disease, also known as "sloth fever," and Zika virus, can be particularly dangerous for those who are pregnant.
