Respiratory Syncytial Virus

Respiratory syncytial virus (RSV) is a highly contagious virus that mainly affects the lungs and respiratory system. It is a major cause of lower respiratory infections in young children, and in some cases, can lead to serious illnesses, such as bronchiolitis and pneumonia. RSV is also a cause of disease in older adults, those with weakened immune systems, premature infants, and those with chronic lung and heart disease. The virus spreads easily by contact with contaminated surfaces and droplets in the air when an infected person coughs, sneezes, or talks. Vaccines to protect against RSV are not available. Prevention involves good hygiene practices, such as washing hands and avoiding contact with those who are infected. Treatment typically includes rest and an over-the-counter medication to reduce symptoms.
