Even in the event of an ongoing outbreak, it was found that early detection and intervention can help mitigate the spread of influenza. For instance, studies have revealed that during the 1918 flu pandemic, cities in the United States that enforced early interventions had significantly reduced mortality rate (Hatchett et al. 2007) . Furthermore, during a pandemic, various influenza-like illnesses (ILIs), as well as non-pandemic seasonal influenza cases will continue to present themselves within the population. The ability to differentiate between the pathogenic strains and the less harmful ones can help channel antiviral drugs to where they are needed. Such targeted treatment is invaluable in the face of limited drug supplies, especially in developing countries.
