A chest X ray revealed no signs of pneumonia.A specific virus was suspected and a rapid test for that virus yielded a positive result.The virus is a negative sense single stranded RNA virus. It has spherical fors that are 150-200 nanometers in size and filamentous forms that are 50 nanometers in size. The surface of the virus has F snd G lipoproteins. The virus also makes a Matrix protein that it uses for building from the host cell.The infant was placed on oxygen therapy and given ribavirin and steroids.

The virus belongs to Paramyxoviridae which is a family of viruses in the family Mononegavirales. There are about 49 species in this family, divided among 7 genera. Vertebrates, especially humans, are a natural host for this viruses. They cause respiratory tract infections among infants, commonly bronchitis.
Ribavirin is an antiviral drug and is used to treat such infections in combination with steroids.
