Cerebritis in typhoid fever.

after 30 days of infection when antigen is no longer detected. The presence of viral antigen and a fourfold rise in antibody titre in seven children indicated a current infection. However, six children testing positive for virus antigen did not have detectable virus specific antibody probably due to maternal antibody masking the IgG response in the infants(8). It is concluded that RSV is an important etiological agent causing bronchiolitis and bronchopneumonia. Exposure to RSV was virtually universal since almost all children above one year had antibodies against RSV. Early viral diagnosis by rapid tests like enzyme immunoassay could help in reducing the unnecessary use of antibiotics.
