Mosquito nets remain a powerful weapon against malaria, but research warns their long-term effectiveness is under threat

Article excerpt

Insecticide-treated mosquito nets reduce malaria cases by up to 68%, according to a major analysis of 25 studies across Africa and Asia. Yet researchers warn the intervention faces mounting challenges that could erode its effectiveness over time. The findings underscore nets' continued importance as a malaria control tool while flagging emerging threats, likely including insecticide resistance, declining net use, and maintenance issues, that require urgent attention to sustain the public health gains of recent decades.
