Influenza A H7N7

H7N7 was firstly detected in chickens in Italy in 1902. Since then, H7N7 viruses have been widely detected in wild birds and domestic poultry around the world. There are highly pathogenic strains and low pathogenic strains of influenza H7N7. H7N7 avian influenza viruses can cross-species (birds, pigs, seals, and horses) and transmit to humans.
The first reported human infection of H7N7 virus occurred in England in1996, when a woman exposed to ducks developed conjunctivitis. In 2003, an outbreak of highly pathogenic H7N7 virus occurred in the Netherlands, resulting in the culling of more than 30 million birds. During this outbreak, 86 humans involved in the culling operation and three of their family members who did
not have direct contact with infected poultry were confirmed to have H7N7 virus infections, suggesting that limited human-to- human transmission of the H7N7 virus occurred. In 2013 in Italy, three poultry workers with conjunctivitis were diagnosed with highly pathogenic H7N7 avian influenza virus infections. This represents a pandemic threat.
