Summary

This study looked at how people's immune systems react to proteins in mosquito saliva after being bitten. Researchers exposed 147 healthy adults in Thailand to lab-grown mosquitoes that can carry malaria or dengue. The goal was to find markers in the blood that show how much exposure a person has had to these mosquitoes, which could help predict disease outbreaks and test mosquito control methods.
