Generally speaking, the prognosis for most cases of bronchiolitis capillaris is good, with a duration of 5-9 days. However, it is worth noting that children who have suffered from capillary bronchitis are prone to asthma in the future, so during the recovery period of capillary bronchitis it is important to pay attention to preventing recurrence of the disease and reducing the occurrence of asthma. It is generally important to keep warm during the recovery period because cold stimulation can reduce the local resistance of the bronchial mucosa. Parents should increase or decrease clothing for the child in time with the change of temperature, especially sleep with a good blanket to keep the body temperature above 36.5℃.
