Attention should be paid to identifying children at high risk of developing severe infection. There are various detection methods to determine RSV infection，which should be selected rationally. The treatment for RSV infection is mainly symptomatic support，and recent progress in drug research and development is expected to achieve a breakthrough in treatment.
