Upper Respiratory Infection
Upper respiratory infections (URIs) typically begin with the entry of pathogens, such as viruses or bacteria, into the mucosal surfaces of the upper respiratory tract. This initial invasion triggers an inflammatory response, leading to symptoms such as nasal congestion and sore throat as immune cells migrate to the site of infection. As the infection progresses, it can spread to adjacent tissues and, in some cases, the lower respiratory tract, potentially affecting the lungs. Key systems affected include the respiratory system, where structures such as the nasal passages, throat, and bronchi become inflamed, and the immune system, which responds to the invaders. Ultimately, most URIs resolve with appropriate care, but complications can arise, especially in individuals with weakened immune systems.
