Most cases of viral pneumonia in infants do not have sequelae. However, severe viral pneumonia may be combined with other diseases resulting in heart muscle damage or cerebral palsy. 1. Most viral pneumonias are treated with timely medication and usually have no sequelae, and recover as normal. 2. If viral pneumonia is not treated in time, it may be combined with other diseases to cause sequelae, for example: when the baby’s lung function declines and severe oxygen deprivation, it may cause cerebral palsy, resulting in retarded mental development or abnormal motor development, and so on. However, the probability of infant viral pneumonia causing sequelae is not high, parents should not worry too much, but need to consult the pediatrician in time to deal with.
