The first case of a human being infected with the H5N8 avian influenza strain has been reported, and experts warn that it may be “the tip of the iceberg.”
The World Health Organization was warned after the first case of a human infected with the H5N8 avian influenza strain was detected in Russia.
National health observer Rospotrebnadzor revealed that the virus was detected in seven workers at a poultry farm in southern Russia after a bird outbreak was recorded in December.
Anna Popova, head of the consumer health organization, said each worker is believed to have caught the virus from birds on the farm and there are no signs of human-to-human transmission.
“A few days ago we were completely convinced of our results,” she said in a television statement.
Workers did not suffer from serious health problems and all recovered from the virus.
“Information on the world’s first case of bird flu (H5N8) infecting humans has already been sent to the World Health Organization,” Popova said.
The H5N8 strain is extremely deadly to wild birds and poultry, but this is the first time it has been reported in humans.
The H5N1 strain is the most common subspecies of avian influenza and is known to infect humans and other animals.
The first human infection with bird flu was detected in 1997 after an outbreak of the virus in Hong Kong poultry.
H5N1 can cause serious illness in humans, with a moral rate of about 60%. According to WHO.
The majority of human bird flu infections are associated with infected live or dead birds, or people in close contact with a virus-contaminated environment.
Infections between humans are “abnormal,” the organization said.
Ms. Popova praised “an important scientific discovery,” saying she “will know over time” whether the virus could mutate further.
“Discovering these mutations when the virus has not yet acquired the ability to transmit from person to person gives us all time to respond appropriately and in a timely manner in preparation for possible mutations. “She said.
WHO confirmed that it had been notified of the Russian infection and worked with authorities to “gather more information and assess the public health impact of this event.”
“If confirmed, this is the first time H5N8 has infected people,” he said.
Gwenael Vourc’h, director of research at the French National Institute for Agricultural and Food Environment, said the influenza virus was known to evolve “very rapidly” and may have had cases other than those reported in Russia. Said there is.
“This is probably the tip of the iceberg,” she told AFP.
The Russian Vektor State Virology and Biotechnology Center has already shown that it is ready to detect potential cases of human H5N8 and begin developing test kits to help initiate vaccine research.
