Reacción a "Man infected with H5N2 avian influenza virus dies in Mexico"

The H5N2 in Mexico belongs to a distinct family of H5 viruses known to have been circulating in local birds for some time and is therefore quite different from other H5s causing sporadic human cases. It is not without precedent that we see very occasional reports of the detection of influenza A viruses from birds in severe human cases when there are major underlying health issues. The role of this virus in the fatal outcome cannot be assumed to directly responsible without further investigation. The prompt follow up in healthcare professionals and family members in contact with the infected patient provides reassurance at present this is an isolated case.
