Surveillance of Influenza Virus Shedding and Immunologic Response in Immunocompromised Children and Young Adults


This study aims to do the following;

- To evaluate the frequency of influenza virus infections due to various subtypes in
immunocompromised children and young adults at SJCRH

- To describe and compare the clinical course and outcome of pandemic H1N1 influenza
infection with that due to other influenza virus subtypes in immunocompromised children
and young adults.

- To evaluate the duration of influenza virus shedding in immunocompromised children and
young adults.

- To evaluate the immunologic response to natural infection with various subtypes of
influenza virus including the pandemic H1N1 influenza A virus.

- To evaluate the viral resistance to antiviral agents in relation to antiviral therapy.

- To compare accuracy of rapid methods for influenza A subtyping and for determination of
antiviral resistance.

using Polymerase Chain reaction (PCR) assay, direct antigen detection assay, or viral
culture.
