2009 Influenza A(H1N1) 'Swine Flu' Outbreak: U.S. Responses to Global Human Cases [May 26,2009] [open pdf - 869KB]
The CRS reports states that "Investments that the United States and other stakeholders have made to prepare for a possible influenza pandemic, and to monitor the spread of other infectious diseases, have been applied to the most recent global response to H1N1. While health experts have made considerable gains against the disease, questions remain. Some health experts are concerned that poorer countries may not yet have the capacity to sufficiently monitor and respond to H1N1. Others warn that H1N1 transmission might accelerate in winter months. Questions still remain about whether the disease can change or reassort, particularly should outbreaks in countries simultaneously contending with H5N1 bird flu cases occur (such as Egypt, Vietnam, and Indonesia)."
