TUESDAY, July 28 (HealthDay News) -- Antiviral drug treatment of swine flu may be wasted on the elderly and should be reserved for young people, suggest researchers who created a model of the effect of antiviral treatment on the spread of the H1N1 virus.
If the current swine flu pandemic behaves like the 1918 flu, antiviral drugs would not significantly reduce death rates among people older than 65 and, in fact, might cause the H1N1 virus to develop increased drug resistance, according to Stefano Merler, of the Bruno Kessler Foundation in Italy, and his colleagues.
"Although it is too early to confidently predict some important features of the ongoing influenza pandemic, the use of antivirals is confirmed to be the most effective single intervention, in the absence of vaccines," Merler said in a news release from the journal's publisher. "It requires, however, a very large stockpile of antiviral drugs. Our work demonstrates that, even in countries where the antiviral stockpile is not sufficient to treat 25 percent of the population, the minimum level suggested by
, it is possible to reduce morbidity and excess mortality by prioritizing the use of antivirals by age."
