RSV in severe cases may be necessary to provide intravenous (IV) fluids and humidified oxygen. Mechanical ventilation is a breathing machine to ease breathing. A nebulized bronchodilator such as albuterol (ProAir HFA, Proventil-HFA, Ventolin HFA) may be used to relieve wheezing. This medication opens air passages in the lungs. Nebulized means it's administered as a fine mist that you breathe in. Occasionally, a nebulized form of ribavirin (Virazole), an antiviral agent, may be used.
Out of 400 patients, 66 were found to have influenza viruses (35, 27, 2, and 2 with types A, B, C, and A and B co-infections, respectively). Influenza viruses were detected in 28, 33 and 5 patients in the age groups <1, 1–10, and 11–30 years old, respectively but none in the 31–50 years old group. Out of 334 patients negative for influenza viruses, 27, 14, and 2 were positive for human respiratory syncytial virus, rhinovirus and adenovirus, respectively.
