The World Health Organization (WHO) has reported the world's first death of a person infected with a laboratory-confirmed avian influenza A (H5N2) virus. The case was reported from Mexico, the WHO reported on Wednesday evening in Geneva. Several laboratory analyses had confirmed the virus type. From 2003 to May 2024, a total of 463 deaths were reported to the WHO from 23 countries following infection with avian influenza viruses, but they were always A (H5N1).
Infections with bird flu viruses must be reported. In many countries, however, not all deaths with bird flu-like symptoms such as respiratory problems or diarrhea are investigated or the laboratory capacity is not sufficient to identify viruses. It is therefore obvious that not every case is reported to the WHO.
The WHO once again called on all countries to be vigilant and to closely investigate clusters of illness. "Based on the information available, WHO considers the current risk to the general population from this virus to be low," the WHO stated.
The case was the first ever bird flu death in Mexico. The person (59) had had several other illnesses. After several weeks of illness, she suddenly had a high fever and shortness of breath, was taken to hospital and died there on April 24. So far, there is no evidence that the person was exposed to infected poultry or other birds. No other infections have been detected among relatives, acquaintances or medical staff who had contact with the person.
Avian influenza is usually transmitted through contact with infected birds. In rare cases, it can also spread from one person to another. However, according to the US health authority CDC, this has happened very rarely so far and has only affected a few people. An infection is usually harmless. However, the viruses could change in such a way that they can be transmitted more easily from person to person. For this reason, vaccine candidates have been developed that can be quickly developed into available remedies in the event of a pandemic.
The WHO also reported that the virus had been detected in poultry in Mexico. In March, an A(H5N2) outbreak was detected in a poultry farm in a backyard in the state of Michoacán - which borders the state of México, where the infected person lived.
