WHO recommendations relating to travellers coming from and going to countries experiencing outbreaks of highly pathogenic H5N1 avian influenza - November 2005

These recommendations are in line with phase 3 in the WHO 6-phase scale of pandemic alert: human infections with a novel influenza virus subtype are occurring, but the virus does not spread efficiently and sustainably among humans. These recommendations may change according to the change in the epidemiological situation and related risk assessments. more

This table displays the cumulative number of confirmed human cases of Avian Influenza A/(H5N1) reported to WHO since the first cases were discovered. more

Key facts about avian influenza (bird flu) and avian influenza A (H5N1) virus  

This fact sheet provides general information about bird flu and information about one type of bird flu, called avian influenza A (H5N1) that is infecting birds in Asia and has infected some humans. more

Ten things you need to know about pandemic influenza 

Avian influenza refers to a large group of different influenza viruses that primarily affect birds. On rare occasions, these bird viruses can infect other species, including pigs and humans. The vast majority of avian influenza viruses do not infect humans. An influenza pandemic happens when a new subtype emerges that has not previously circulated in humans. more

Information about influenza pandemics

An influenza pandemic is a global outbreak of disease that occurs when a new influenza A virus appears or “emerges” in the human population, causes serious illness, and then spreads easily from person to person worldwide. Pandemics are different from seasonal outbreaks or “epidemics” of influenza. Seasonal outbreaks are caused by subtypes of influenza viruses that already circulate among people, whereas pandemic outbreaks are caused by new subtypes, by subtypes that have never circulated among people, or by subtypes that have not circulated among people for a long time. Past influenza pandemics have led to high levels of illness, death, social disruption, and economic loss. more
