Children with asthma do poorly in response to viral infections. Any viral infection can trigger asthma. The most common viral infection is the common cold and it is one of the leading causes of wheezing in children. Similarly, the seasonal flu virus can also aggravate asthma. Children with mild asthma can get very sick when they catch the flu virus. So, it is highly recommended that all children with mild or severe asthma should receive a yearly flu vaccine.
