Co-COV-COV-2 and Influenza A Virus Coordination does not change the path, or the severity of the influenza A virus, regardless of time. But if someone contracts the influenza A virus first, the response to the infection can significantly press SARS-COV-2, according to research.”This research is important, because the human population now has two respiratory RNA viruses circulating with high pandemic potential: SARS-COV-2 and Influenza A,” said researchers from New York University, Langone.
.
In particular, the influenza A virus interferes with SARS-COV-2 replication in the lungs and can continue to do it even more than one week after cleaning influenza A, according to research published in the Journal of Virology.”This data shows the presence of intrinsic factors or induced by [influenza A virus] which can limit the growth of SARS-COV-2, but it is still unclear whether this effect plays a role in the severity of the disease,” the researchers wrote.
The researchers conducted experiments in cultured cells, as well as in the gold hamster model. “An animal is given 2 viruses simultaneously, and examined on days 1,3, 5, 7 and 14 post -infections,” said the author who was in accordance with Benjamin R. Tenoever, Professor of Microbiology, in Nyu.The researchers also conducted an experiment where they first challenged animals with viruses, followed by three days later by other viruses, monitoring [them] on days 1, 3, and 5 post-second challenges.
“This study can be used as an example of how immune responses to something unrelated can provide protection for SARS-COV-2,” Tenoever said.The team showed that coinfection did not produce worse diseases in animal models. The results of acethese show that coinfection with the SARS-COV-2 virus and Influenza A does not represent a towering threat to humanity, “Tenoever said.
