Skin smell predicts mosquito attraction

A lab study with Aedes aegypti identified ~27 human skin odorants mosquitoes detect and found small increases in a sebum‑breakdown product (1‑octen‑3‑ol, 'mushroom alcohol') make some people, including some second‑trimester pregnant women, measurably more attractive to biting females. The result links specific, testable biochemical markers to differential mosquito biting in humans. — If real and generalizable, the finding could reshape public‑health strategies for vector control, pregnancy guidance, and personalized repellents by focusing on measurable odor cues rather than blunt population measures.
