Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to describe participants seeking medical care in geographically diverse locations with 2009 H1N1 infection and their clinical course over a 14-day period following enrollment.

Description: Death or hospitalization within 14 days of enrollment or the development of one severe complication.
Measure: Death or Hospitalization Time: 14-day period following enrollmentThe study will be conducted using nasopharyngeal swab specimens collected prospectively from individuals suspected of having the signs and symptoms of an acute respiratory tract infection caused by a respiratory virus. A series of standard viral culture tests validated for routine use in the clinical laboratory, and/or a series of PCR-based Laboratory Developed Tests (PCR-LDT) validated by a central reference laboratory will be used to verify the performance of the investigational artus Influenza A/B RT-PCR test and the QIAGEN ResPlex II Advanced Panel test. From each specimen five (5) aliquots will be prepared: (a) one aliquot will be tested in real-time using the assigned viral culture reference methods; (b) one aliquot will be used to extract nucleic acid in real-time for investigational testing; (c) one aliquot of the specimen will be stored at --70C for subsequent shipment to the reference laboratory for PCR-LDT testing, (d) one aliquot will be archived at -70C for subsequent follow-up by the reference laboratory (e.g., bi-directional sequencing of positive specimens), and (e) any remaining specimen will be stored for the Fresh vs. Frozen Study. The extracted nucleic acid generated from the second aliquot (i.e., "b" above) will be split and subjected to testing by both the artus Influenza A/B RT-PCR test and the ResPlex II Advanced Panel test.

Measure: Detection of Respiratory Viruses Time: Specimens will be taken within 5 days of the appearance of symptoms.Currently, there is no treatment for children less than one year of age with influenza related lower respiratory tract infection that is either considered standard or registered in any country. This dismal scenario exists even though influenza related LRTI is a significant illness causing morbidity and mortality, especially in children less than 6 months of age. Avian influenza has been reported rarely in children less than one. There are no data in Vietnam and very few data in Thailand on the burden of influenza in children less than one. This young age group suffers high mortality. Oseltamivir may be beneficial in such children. This is basis of this trial.

Description: An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product. A serious adverse event (SAE) is any significant hazard, contraindication, side effect that is fatal or life-threatening, requires hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability/ incapacity, is a congenital anomaly/ birth defect, is medically significant or requires intervention to prevent one or other of the outcomes listed above.
