Abstract

In the early phase of the 2009 A (H1N1) pandemic a marked increase in severity and a shift in the age distribution toward younger persons was found, with higher severity reported in patients with pre-existing medical conditions and pregnant women. Consistent with previous pandemics, the age and clinical history of the patients play a critical role in the morbidity and mortality associated with the pandemic virus. This is the first influenza pandemic in the information era, where enormous amounts of information will be available from the pathogen and the patient. Recent advances in molecular techniques have provided an enormous amount of information about pathogens in near real time and at relatively low cost. Electronic Health Records (EHRs) provide another enormously rich set of information about patients, which include patient preconditions, previous exposures, immunization history, presenting complaints, duration and severity of illness, treatment history, and geographic location. An infectious disease is a complex interplay between host and pathogen. The morbidity and mortality of a virus depend on the virus, the patient, and the environment. To evaluate and understand the severity of the pandemic virus and to identify the populations at risk of mild or severe, lifethreatening illness, it is compulsory to integrate viral and patient information in a fast and accurate way. Both advances in biomedical informatics with the creation of EHRs and molecular techniques provide the framework to achieve these aims.
