Beer attracts malarial mosquitoes to humans
We’ve all heard about “beer goggles”, the mythical, invisible eyewear that makes everyone else seem incredibly attractive after a few pints too many. If only beer had the reverse effect, making the drinker seem irresistibly attractive. Well, the good news is that beer does actually do this. The bad news is that the ones who are attracted are malarial mosquitoes.
Anopheles gambiae (the mosquito that transmits malaria) tracks its victims by their smells. By wafting the aromas of humans over thousands of mosquitoes, Thierry Lefevre found that they find the body odour of beer drinkers to be quite tantalising. The smell of tee-total water drinkers just can’t compare. The somewhat quirky conclusion from the study, albeit one with public health implications, is that drinking beer could increase the risk of contracting malaria.
