1. RPV virus - the cause of pneumonia in children
Respiratory syncytial virus (RSV) is a virus that infects the lungs and respiratory tract, causing bronchiolitis, pneumonia. The RSV virus enters the body through the eyes, nose, or mouth.

Children are at risk of contracting the virus if they accidentally touch objects that have the virus on them and put them in their mouths. The disease develops strongly in winter - spring and spring - summer.Most children get respiratory syncytial virus before 2 years of age. In addition, the RSV virus can also infect adults. After being infected with RSV virus, it can take 2-8 days for a person to show symptoms. In healthy adults and children, symptoms of RSV infection are usually mild, like the common cold, and home-care measures can be used to ease discomfort. However, respiratory syncytial virus infection can also be serious in some cases, especially in premature infants and infants with underlying health problems, causing bronchiolitis or pneumonia, respiratory failure, and respiratory failure. Rapid breathing, very dangerous for children. In addition, the disease can also become more serious in the elderly, people with heart or lung conditions, or with weakened immune systems.
