Studies have shown that simultaneous infection with influenza and the new coronavirus (SARS-CoV-2) may suppress the growth of SARS-CoV-2. It may be the result of some reassurance as experts become more alert to the simultaneous epidemic of these two viruses.

Influenza A virus (IAV) was found in the new coronavirus infection (Covid-19) in experiments with animals (hamsters), according to a read paper published in the journal of virology, the journal of virology. The results show that it inhibits the replication of SARS-CoV-2, the causative virus.

IAV is one of four seasonal influenza viruses and is the only influenza virus known to have caused a pandemic in the past. According to Benjamin Tenover, a professor of microbiology at New York University’s Grossman School of Medicine, who published the paper, SARS-CoV-2 replication in the lungs of hamsters was suppressed for more than a week after the influenza virus was eliminated. ..

It is believed that simultaneous infection did not affect SARS-CoV-2’s post-infection course or symptoms of IAV. However, IAV (especially if previously infected) significantly inhibited SARS-CoV-2 replication.

These results suggest that some factor that IAV has or is caused by IAV suppresses the proliferation of SARS-CoV-2. But it’s unclear if it affects the severity of Covid-19’s symptoms.

The researchers say more research is needed to determine if the results from this study apply to other strains of humans and viruses.

Is it unlikely that co-infection will lead to aggravation?

With the outbreak of the SARS-CoV-2 pandemic, most of the regulations that were being implemented in various places to curb the spread of infection are now being relaxed or abolished. Under these circumstances, experts are increasing caution that more people may be infected with these two viruses at the same time.

Professor Tenover pointed out that in the early days of the pandemic, where masks and social distance were not required, there were many cases of co-infection with influenza and SARS-CoV-2. That’s why there is growing concern that these syndemics could exacerbate the pandemic situation, he said.

However, the results of research by Professor Tenover et al. On the co-infection of SARS-CoV-2 and IAV, which are also called “Fururona” (of course, not the official name), together with the influenza “Full” and the coronavirus “Rona”. Suggests that it is “not a threat to humankind.”

However, in March of this year, although there was insufficient evidence to support the claim, those who were infected with influenza and SARS-CoV-2 at the same time (if neither vaccine was given) had SARS. -Studies have also shown that people are twice as likely to die and four times more likely to need a ventilator than people infected with CoV-2 alone.
