Spread through coughing, sneezing, or close contact

RSV is spread through coughing, sneezing, or close contact with an infected person. The virus can also be spread by touching surfaces or objects that have been contaminated with the virus and then touching your mouth, nose, or eyes.

• Coughing and sneezing
  

  When an infected person coughs or sneezes, they release droplets of fluid containing the virus into the air. These droplets can be inhaled by others, who can then become infected.

• Close contact
  

  RSV can also be spread through close contact with an infected person. This can include kissing, hugging, or sharing food or drinks.

• Touching contaminated surfaces or objects
  

  RSV can survive on surfaces for up to several hours. If an infected person coughs or sneezes on a surface, the virus can live on that surface and infect others who touch it and then touch their mouth, nose, or eyes.

• Person-to-person contact
  

  RSV is most commonly spread from person to person through close contact, such as living in the same household with an infected person or attending daycare or preschool.

RSV is a highly contagious virus, and it is important to take precautions to avoid infection. These precautions include frequent handwashing, covering your mouth and nose when you cough or sneeze, and avoiding close contact with people who are sick.

Most common cause of bronchiolitis and pneumonia

RSV is the most common cause of bronchiolitis and pneumonia in infants and young children. Bronchiolitis is an inflammation of the small airways in the lungs, while pneumonia is an infection of the lungs. Both of these infections can be caused by bacteria or viruses, but RSV is the most common cause of viral bronchiolitis and pneumonia.

RSV bronchiolitis and pneumonia typically begin with cold-like symptoms, such as a runny nose, cough, and fever. However, these symptoms can quickly worsen, leading to difficulty breathing, wheezing, and chest pain. In severe cases, RSV bronchiolitis and pneumonia can lead to hospitalization and even death.

Infants and young children are at highest risk of severe RSV bronchiolitis and pneumonia because their immune systems are not fully developed and they have smaller airways, which can become easily blocked by swelling and mucus.

There is no specific antiviral treatment for RSV bronchiolitis and pneumonia. Treatment is supportive and may include oxygen therapy, fluids, and medications to relieve symptoms. In severe cases, hospitalization may be necessary.
