Researchers want to understand why some people develop allergies like asthma and eczema while others don't. This study will look at the bacteria and other microorganisms living on and inside people's bodies, and compare those with their home and outdoor environments. By studying families and healthy neighbors in Mali, the researchers hope to discover whether differences in bacteria, water quality, or air pollution help explain who gets these allergic diseases.
Asthma and eczema are becoming more common around the world, but we don't fully understand why some people get them and others don't. Scientists believe that the bacteria living on our skin and in our gut, combined with exposures to pollutants in our homes and neighborhoods, may play an important role. This study aims to uncover those connections so that doctors can better prevent and treat these conditions.

You will visit a clinic in Bamako where researchers will ask you questions about your environment and health history. You'll have basic breathing tests and a quick skin scan. You'll provide samples including skin swabs, nasal swabs, blood, stool, and a saliva sample. Researchers will also collect samples from your home's drinking water and the air around your neighborhood. The entire process is observational—there is no medication to take—and is designed to understand how your surroundings and body's natural bacteria may relate to allergies.
