In 1918, the global influenza was caused by pigs

Introduction: scientists have made another shocking new discovery: the virus prevalent in animals may also break the boundaries between humans and animals and threaten humans In 1918, the worldwide pandemic influenza was caused by the integration of human influenza virus with a piece of DNA of swine influenza virus According to science in early September, two virus experts from the University of Wisconsin studied avian influenza in 1997 and human influenza in 1918, both of which broke the species boundary In 1997, avian influenza not only killed thousands of poultry, but also infected 18 patients, six of whom died successively And the 1918 human flu was incredibly related to pigs - the DNA of the pig virus appears in the human virus This brand-new virus suddenly makes the human immune system lose its function, leading to disaster To what extent can animal viruses threaten humans? Professor Li Ning, deputy group leader of bioengineering technology subject expert group of national 863 program, told reporters that in the past, the scientific community believed that animal viruses would not infect people, but now there are new discoveries, at least in the laboratory, animal viruses have been found to be able to invade human cells In view of the fiercely debated experiments of human and animal cell fusion in China, Professor Li believes that it is possible to create a kind of uncontrollable monster like opening the Pandora box, so as to make new animal viruses enter the human body in a favorable way, or to find a way to treat difficult diseases But in any case, scientists should be engaged in research in a safe and closed environment to prevent human beings from being hurt by the sword of science (author:) share to feed Weibo share to:
