In birds, avian influenza viruses are shed in the faeces and respiratory secretions. They can all be spread through direct contact with secretions from infected birds, especially through faeces or through contaminated feed and water.
6 lut 2024 · Highly pathogenic avian influenza virus (HPAIV) A H5, particularly clade 2.3.4.4, has caused worldwide outbreaks in domestic poultry, occasional spillover to humans, and increasing deaths of...
1 maj 2024 · By fitting a model simulating H9N2 AIV transmission to data from a field experiment, we characterise the epidemiology of the virus in a live bird market in Bangladesh.
5 sie 2024 · Evolutionary mechanisms. Mutations and antigenic drift. Like many RNA viruses, AIVs have been undergoing rapid evolution due to their error-prone RNA polymerase. Genetic mutations emerge and accumulate during virus replication within infected hosts.
3 paź 2023 · Currently circulating zoonotic influenza viruses have not yet demonstrated sustained person-to-person transmission. As influenza viruses have a natural reservoir in aquatic birds they are impossible to eradicate. Zoonotic influenza infections will continue to occur.
Avian influenza (AI), also known as “bird flu” is a contagious disease among the poultry population with high avian mortality, causing a decrease in production, generating economic losses, and limiting the circulation of birds, its products, and subproducts.
