1. Respiratory Tract Infections in CVID

Common Variable Immunodeficiency (CVID) is a condition that affects the immune system, making individuals more susceptible to infections. One of the most common types of infections they face are respiratory tract infections, which include issues like frequent colds, pneumonia, or sinus infections. This happens because their bodies struggle to produce enough antibodies to fight off bacteria and viruses that cause these infections. Consequently, people with CVID may experience more severe or prolonged illnesses compared to those with a healthy immune response. Management often includes medication and vaccinations to help protect against these infections.
