Malaria, a deadly disease spread by mosquitoes, is becoming harder to treat as parasites are developing resistance to the key drug, artemisinin.
The resistance is spreading rapidly across East Africa, with over 20% of cases showing resistance in some regions.
This could lead to a dramatic increase in malaria cases and deaths, similar to what happened in Southeast Asia when the parasite became resistant to another drug.
Scientists are calling for urgent action to prevent widespread resistance, including new drug combinations, better prevention methods, and increased funding for research.
