Table: Human cases of H5N1 bird flu (Posted after July 8 Update: Numbers subject to change)
On this page you’ll find detailed information about each human case of H5N1 bird flu since 2021, when a new variant spread across most of the world. This page is updated regularly and as soon as possible when a human case is reported.
The current variant of concern is 2.3.4.4b, which has spread to a growing number of mammals since it was first discovered in late 2020. The first human case was reported in the UK in January 2022. An older variant (2.3.2.1c) is endemic in Cambodia and occasionally causes human cases.
It’s currently not possible to predict the death rate for clade 2.3.4.4b. Most of the cases to date were picked up during random surveillance of poultry and cattle workers, which skews the data towards asymptomatic and mild cases. Only 4 cases have occurred in the community, causing severe illness in all cases and resulting in 1 death.
Definitions
Reported: The month in which a case was publicly reported. The actual infection or the onset of symptoms may have occurred weeks earlier. Some countries (especially China) take anywhere between days or weeks to publicly report a case. Gotta love singling out China for reporting speed, especially in the context of the US and other Western countries fumbling their management of this emerging public health crisis so badly, that we're literally not testing.
Symptoms/Outcome
None: The patient did not report any symptoms (asymptomatic).
Mild: The patient experienced symptoms which did not require hospitalization or they were hospitalized but only for observation.
Severe: More serious symptoms requiring hospitalization, especially ICU treatment.
Recovered: The patient survived the active infection of H5N1 bird flu. Some patients have long-term or permanent health issues caused by the illness.
Died: The patient died while undergoing treatment for H5N1.
Unknown: No reliable information is available about the outcome of the case, which often happens when the patient is still hospitalized at the time of the announcement and no further updates are released.
Other data notes
Because we can only display one source in the table, the cited link may not include all available or up-to-date information.
Some cases may be assigned to a specific clade before laboratory studies are complete. For example, a person testing positive for H5 bird flu may be listed as H5N1 if they worked on a farm where animals were infected with H5N1.
