Policy Response to Pandemic Flu
October 26, 2011
The world experienced four influenza pandemics in the last 100 years; the deadliest of these, in 1918, killed roughly three percent of the world’s population. An influenza pandemic is still a threat: the relatively mild 2009 H1N1 strain spread rapidly through the global transportation network, long before a vaccine was available. Antiviral drugs can help slow the spread of a pandemic and reduce the numbers of cases, but many low-income countries cannot afford to purchase and stockpile these drugs.
While wealthy countries can use antivirals to reduce their own rates of infection, could supplying additional doses to low-income countries during a pandemic result in even lower infection rates in wealthier nations? Can a purely economic case be made for wealthy countries to provide treatments to lower-income nations?P>
In “Policy Response to Pandemic Influenza: The Value of Collective Action,” RFF Senior Fellow Maureen Cropper and coauthors attempt to answer this question. Their study simulates scenarios in which high-income countries distribute stockpiles of antivirus in low-income countries, and shows that this policy can make both groups better off. They find that the most effective policy is to provide antivirals in the outbreak source country, but that making doses available to other low-income countries can also be effective. Their results also highlight the importance of pandemic surveillance systems and treatment delivery systems in containing or mitigating a pandemic.
