Abstract
Pandemic (H1N1) 2009 virus was detected in breeding turkeys on 2 farms in Valparaiso, Chile. Infection was associated with measurable declines in egg production and shell quality. Although the source of infection is not yet known, the outbreak was controlled, and the virus was eliminated from the birds.

Influenza A pandemic (H1N1) 2009 virus is a novel highly transmissible agent that contains a unique combination of gene segments from different swine lineages (1); it has circulated in humans since April 2009 (2). First detected in North America, the virus was disseminated worldwide in just a few weeks, prompting the World Health Organization to raise its global health alert to the pandemic stage (2,3).

By December 2009, a total of 14 countries had reported that the pandemic strain was infecting swine, generating concern about the role of other susceptible species in the viral epidemiology. Fortunately, only a mild respiratory disease developed in the ill swine, and outbreaks were controlled with biosafety measures, avoiding dissemination to humans and animals (4). In Chile, the first case of human infection with the pandemic strain was confirmed on May 17, 2009; infection increased within 6 months to a total of 12,276 cases, with 147 deaths (5).
