what is rsv in medical terms

RSV stands for Respiratory Syncytial Virus, which is a common respiratory virus that causes infections of the lungs and respiratory tract. It is so common that most children have been infected with the virus by age 2. RSV can cause mild, cold-like symptoms, but it can also cause severe infections, especially in people at high risk, such as infants, older adults, people with heart and lung disease, or anyone with a weak immune system. Symptoms of RSV include fever, severe cough, wheezing, rapid breathing or difficulty breathing, and bluish color of the skin due to lack of oxygen. RSV can also cause pneumonia or bronchiolitis, which is inflammation of the small airway passages entering the lungs. Diagnosis of RSV is usually done through a medical history, physical exam, and lab tests of nasal fluid or another respiratory specimen to check for RSV. Treatment for RSV is usually self-care measures to relieve any discomfort, but in severe cases, hospitalization may be necessary. There are also preventive options available to protect infants and young children from severe RSV, such as vaccines and washing hands often with soap and water for at least 20 seconds.
