Respiratory Syncytial Virus (RSV) is a common respiratory virus that infects the lungs and airways. While most healthy adults experience mild cold-like symptoms, RSV can cause severe illness in infants, older adults, and people with asthma, COPD, heart disease, or weakened immunity. Early medical evaluation is important if symptoms worsen or breathing becomes difficult.
Introduction
Respiratory illnesses increase during periods of seasonal weather change, and Respiratory Syncytial Virus (RSV) is one of the most common viral infections affecting both children and adults.
Although many people have never heard of RSV, it is one of the leading causes of bronchiolitis and pneumonia in infants and can also lead to serious complications in older adults and individuals with chronic lung diseases.
Many RSV infections are mistaken for a common cold, causing delays in diagnosis and treatment.
At Health Adda Hospitals, Dr. ANV Koteswara Rao frequently evaluates patients with persistent cough, wheezing, fever, and breathing difficulty during the seasonal increase in respiratory viral infections.
