Climate change escalates malaria risk for pregnant women in highlands

Rising temperatures are pushing malaria-carrying mosquitoes to higher altitudes, posing a lethal threat to pregnant women in previously unaffected regions.

Zoya Teirstein reports for Grist, Vox and The 19th


In short:

  • Papua New Guinea's highlands are seeing an increase in malaria cases as mosquitoes move to higher elevations due to climate change.
  • Pregnant women in these regions are particularly vulnerable, with severe malaria increasing the risk of maternal and fetal complications.
  • The upward shift of malaria mosquitoes threatens to reverse global progress in malaria control.

Key quote:

"When malaria hits new populations that are naive, you tend to get these explosive epidemics that are severe because people don’t have any existing immunity."

— Sadie Ryan, associate professor of medical geography at the University of Florida.

Why this matters:

Climate change is expanding the range of malaria, endangering pregnant women in highland areas who lack immunity. This trend emphasizes a need for enhanced malaria control measures and healthcare access in vulnerable regions. Read more: Coronavirus, climate change, and the environment.
