J98.7: Respiratory infections, not elsewhere classified

Respiratory infections not elsewhere classified relates to infections in the body's respiratory system, which includes the nasal passages, throat, windpipe, and lungs. Infections can occur when harmful bacteria, viruses, or fungi enter the respiratory system and multiply, causing an inflammatory response. They often follow a cold or flu, but can also arise independently. Symptoms typically include coughing, chest tightness, shortness of breath, and a rapid heart rate. As the infection progresses, it can lead to complications such as pneumonia or respiratory failure. Severity and progression of the infection can also vary widely, from short-term issues, such as a common cold, to chronic conditions, such as bronchitis or asthma. These types of infections affect millions of people per year, of all ages and backgrounds, making it a common health issue worldwide.
