What happened

Increased cases of dengue fever, chikungunya, and malaria have something in common with droughts, floods and wildfires.

Why it matters

The climate crisis is creating the perfect conditions for these infectious diseases to spread further and with more ease as extreme weather events increase in frequency.

Common ground

This was one of the key messages of a lecture that Professor Helen Rees, the executive director of the Wits Reproductive Health Institute, delivered during the Pro-VC Research Seminar at the University of Witwatersrand on Thursday, 30 July.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
