Influenza

Influenza viruses are able to emerge or re-emerge as "new" viruses with the potential to cause worldwide epidemics of influenza. Global surveillance is of critical importance. The clinical spectrum of influenza varies from asymptomatic infection to the classical flu syndrome. Vaccination is the most effective measure for reducing the impact of the disease, and experiences such as the Argentinian National Immunization Campaigns provide a model of massive vaccine administration for other Latin American countries. New antivirals such as neuraminidase inhibitors will offer valuable benefits in the prevention and treatment of influenza.
