Official title

Pilot Study of the Genotypic Analysis of Patients Infected With Influenza Virus Compared With Uninfected Spouse/Close Contact Controls

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Influenza (the flu) is a leading cause of respiratory (breathing) illness that leads to sickness and death during the winter months. A better understanding of why certain people get the flu or get sicker with the flu than other people is important for developing improved vaccines and treatments. This study will look at the genetic makeup (determines each person's specific characteristics and traits) of 50 patients, older than 50, who were hospitalized with flu at Vanderbilt University during the 2006-2007 flu season. Their genetic makeup will be compared with the genetic makeup of 50 people who are not related but were in close daily contact with the flu patient and were not infected with flu virus. The study staff will collect a blood sample (contains genetic material) from each participant (flu patients and their contacts) for comparison. Flu patients will have completed a health survey as part of the previous study, and their contacts will complete a shorter version of this survey.
