Mechanism of contagion
The virus spreads when a person comes into direct contact with the nose and throat secretions of someone who has the disease, either an adult or another child. The usual mechanism of contagion is through tiny droplets exhaled from the nose or bronchi when coughing or sneezing. These droplets can contaminate surfaces, toys and different utensils. There can also be direct contact with contaminated hands.
This means that there are two main paths of contagion:
- When a person with bronchiolitis coughs or sneezes nearby and the baby inhales the tiny droplets they release into the air.
- When a baby touches toys or other objects that have been touched by a person with bronchiolitis.
