Respiratory Syncytial Virus Clinical Trials

RSV is the most common cause of bronchiolitis and pneumonia in children younger than 1 year of age in the United States and easily spreads from person to person. You can get it from direct contact with someone who has it or by touching infected objects, such as toys or surfaces, such as countertops. People infected with RSV are usually contagious for 3 to 8 days. However, some infants, and people with weakened immune systems, can continue to spread the virus even after they stop showing symptoms for as long as 4 weeks. Washing your hands often and not sharing eating and drinking utensils are simple ways to help prevent the spread of RSV infection.


RSV vaccination clinical trials, like those at CNS Healthcare, can help you explore new options. Interested in a vaccination for RSV?

More About Respiratory Syncytial Virus



RSV is caused by a virus and spread when an infected person coughs or sneezes. The virus enters the body through the nose or mouth or very often through the eyes (when people rub their eyes with a hand that has touched infected secretions.)




  • Crowded places with people who may be infected
  • Exposure to other children (e.g., in daycare) or to older siblings attending school
  • Infants younger than 6 months of age
  • Young children, especially those under 1 year of age, who were born prematurely or who have an underlying condition, such as congenital heart or lung disease
  • Children with weakened immune system
  • Adults with asthma, congestive heart failure, or chronic obstructive pulmonary disease (COPD)
  • People with immunodeficiency, including those with certain transplanted organs, leukemia, or HIV/AIDS

Signs & Symptoms

  • Nasal congestion, runny nose, mild cough, and low-grade fever are the typical initial symptoms of both the mild and of the more severe forms of the disease.
  • Barking cough, which can be a sign of significant swelling in and around the vocal cord
  • Fever, either low grade (less than 101 degrees F) or high (more than 103 degrees F)
  • Difficulty breathing with one or more of the following

1.  Abnormally fast breathing (tachypnea)

2. “Caving-in” of the chest in between the ribs and under the ribs (chest wall retractions)

3. “Spreading-out” of the nostrils with every breath (nasal flaring)

  • Wheezing (a high-pitched whistling sound as the patient breathes out)
  • Difficulty drinking
  • Lethargy or irritability
  • Bluish color around the mouth, lips, and fingernails (cyanosis)
  • Apnea (stopping breathing) is a common symptom of RSV bronchiolitis among very young infants, especially those born prematurely
