Standard Influenza Antiviral Stockpiles May Fail in Severe Pandemics

High resource nations may not prevent healthcare systems from becoming overwhelmed during severe influenza pandemics by relying solely on traditional antiviral stockpiles, PLOS Medicine reported. Researchers Nir Gavish and Amit Huppert conducted a modeling study to examine if standard inventory benchmarks can maintain hospital demand within existing healthcare capacity. [1]

Pandemic influenza preparedness in high resource countries has historically depended on antiviral stockpiles designed to cover 25 percent of the population. According to PLOS Medicine, this standard benchmark focuses on total cumulative disease burden rather than the fixed, inelastic limits of hospital capacity during a surge. [1]

Using several modeling approaches and historical outbreak scenarios, the authors found that current stockpiles help during moderate outbreaks. However, PLOS Medicine noted that these supplies are unlikely to prevent severe healthcare capacity pressures when facing larger outbreaks. [1]

The World Health Organization previously declared the H1N1 swine flu pandemic, which lasted from June 2009 to August 2010. That global outbreak involved a triple reassortment of bird, swine, and human influenza viruses combined with a Eurasian pig flu strain. [2]
