Researchers want to understand how children's immune systems respond when they develop respiratory infections like colds, flu, or other common lung infections. This observational study will collect small samples of blood, mucus, and saliva from children who come to the hospital with acute respiratory infections, along with information about their medical care during their hospital stay.
South Africa has high rates of tuberculosis and HIV infection, which affect how children's immune systems work. Understanding how children's immune systems naturally fight respiratory infections in this region can help doctors better treat and prevent serious lung infections in the future.

If you join this study, researchers will collect small samples of blood (about one and a half teaspoons), mucus, and saliva when you first arrive at the hospital. Additional saliva samples will be collected on your second and third days in the hospital, and again when you go home. The research team will also review your medical records, vaccination history, and the treatments you receive as part of your routine hospital care. The samples will be used to study antibodies and immune responses to common respiratory infections.
