A man infected with H5N2 bird flu, the first confirmed human infection with the strain, died from multiple factors, the WHO said Friday (7 June), adding that investigations were continuing.
The World Health Organization announced Wednesday that the first laboratory- confirmed human case of infection with H5N2 avian influenza virus had been reported from Mexico.
Mexico's health ministry said the 59-year-old man had "a history of chronic kidney disease, type 2 diabetes (and) long-standing systemic arterial hypertension".
He had been bedridden for three weeks before the onset of acute symptoms, developing fever, shortness of breath, diarrhoea, nausea and general malaise
on April 17.
The man was taken to hospital in Mexico City on April 24 and died later that day.
"The death is a multi-factorial death, not a death attributable to H5N2," WHO spokesman Christian Lindmeier told journalists in Geneva on Friday.
"The patient came to the hospital after weeks of multi-factorial background of multi other diseases," he said.
His body was subsequently routinely tested for flu and other viruses, and H5N2 was detected, Lindmeier said.
Seventeen contacts of the case in the hospital were identified. All tested negative for influenza.
In the man's place of residence, 12 contacts in the weeks beforehand were identified. All likewise tested negative.
"Investigations are ongoing. Serology is ongoing. That means the blood testing of contacts to see if there was any possible earlier infection," Lindmeier said.
"The infection of H5N2 is being investigated to see whether he was infected by somebody visiting or by any contact with any animals before."
The WHO said Wednesday that the source of exposure to the virus was unknown, though H5N2 viruses have been reported in poultry in Mexico.
Based on available information, the United Nations' health agency assesses the current risk to the general population posed by the virus as low.
