Ten cases of avian influenza, primarily affecting pelicans, have been reported by the National Animal Health Service (SENASA) in Costa Rica within a month of the first detection. The outbreak, largely contained in coastal regions, includes one case in a hawk and a domestic bird, prompting SENASA to maintain vigilance and reinforce biosecurity measures in poultry farms. SENASA is collaborating with the Ministry of Health to monitor the situation and ensure human health. International experts recommend continued surveillance and investment in science to develop a universal vaccine against the flu virus, while assuring the public that eating well-cooked poultry products is safe.
