US experts have found that influenza viruses can survive for decades after freezing. US researchers have announced that influenza viruses may survive in frozen lakes for decades or more, and may be infected by birds and transmitted to other animals and humans.
The researchers wrote in the Journal of Virology that the frozen virus could be the source of a new epidemic, causing people to die or even die decades later.
Dr. Scott Rogers of Bowling Green University in Ohio said: "We found viral RNA in the icy lakes of Siberia. These lakes are the only way for migratory birds to fly to Asia, North America, Europe and Africa. ."
He said that observing where the ice melted and which virus the bird was infected with, the prediction of the virus that will be popular in the second year may be more helpful. Every year, WHO and experts try to predict which type of flu virus will be prevalent in the second year and recommend that the company produce a vaccine to prevent the flu virus.
In 2001 and 2002, Rogers and his colleagues from the Russian Academy of Sciences extracted samples from three lakes in northeastern Siberia. They found that an H1 virus that was prevalent from 1933 to 1938 reappeared in the lake in the 1960s, with the largest number of wild geese infected by this type of virus.
The report pointed out that the spread of the H5N1 avian influenza virus is largely due to migratory migratory birds. The virus caused about 200 million birds worldwide to be slaughtered. Meditech Medical Devices Network
