Right here’s the factor: Sure, it’s potential to get sick with a number of viruses on the identical time. You can too catch colds and different sicknesses shortly after recuperating from COVID. None of that is enjoyable, particularly should you’re attempting to get again into the swing of “actual life” after years of quarantine and social distancing. So, what’s occurring? May a diminished immune system or an altered COVID-19 virus be in charge?
We talked with an infectious illness physician and a pulmonologist to get a way of whether or not having COVID a number of occasions might weaken your immune system and make you extra prone to different viruses or if we’re coping with one thing else.
So, can having COVID a number of occasions weaken your immune system?
In case you’ve been contaminated with COVID a number of occasions (and hundreds of individuals have), chances are you’ll be involved about your ongoing vulnerability to different circulating illnesses. If that’s the case, most specialists say to not fear. At present, there isn’t any confirmed hyperlink between getting COVID-19 and long-term, elevated susceptibility to different contagions, like viruses or bacterial infections. (Nonetheless, having lengthy COVID can enhance your danger for serious health issues, based on new analysis.)

“An acute an infection similar to COVID and different viral infections, in addition to many extreme bacterial infections, can ‘occupy’ the immune system for a time frame. This may increasingly make you extra susceptible to a brand new an infection that comes alongside. Though numerous COVID variants and sub-variants, in addition to different pathogens, have methods of evading or combating our immune system’s defenses, there isn’t any strong proof that any lasting detrimental affect happens with COVID,” says Charles Bailey, MD, medical director for an infection prevention at Providence St. Joseph Hospital and Providence Mission Hospital in California.
In different phrases, there’s nothing about COVID particularly that weakens your immune system or makes you extra prone to different sicknesses. So why does it appear to be so many individuals are getting sick with all types of issues this 12 months?
This prolonged interval of low publicity to usually circulating pathogens decreased herd immunity, producing the incidence of what’s referred to as an “immunity debt.”
COVID precautions decreased publicity to widespread circulating viruses
For a number of years, sporting masks and social distancing was crucial to guard the inhabitants from extreme signs and harmful issues like pneumonia and dying. Along with defending individuals from COVID, taking these measures additionally saved different sicknesses at bay in adults and kids, together with widespread colds, influenza, bronchiolitis, and RSV.
In response to researchers in France, this prolonged interval of low publicity to usually circulating pathogens decreased herd immunity, producing the incidence of what’s referred to as an “immunity debt.” Since this isn’t a longtime time period in epidemiology, there was some misunderstanding about what it really means. Masking and social distancing didn’t weaken our immune programs—however they did briefly scale back our publicity to those pathogens. As behaviors have modified, these pathogens have unfold extra readily. So, a extra correct time period is definitely “immunity gap.”
We’ve seen this immunity hole in motion within the larger-than-normal inhabitants of infants and toddlers grappling with RSV an infection this 12 months.“Infants, after all, are born on a regular basis and normally get contaminated with RSV by age 2. Nonetheless, over the last two years of isolation and social distancing, many infectious respiratory illnesses didn’t make their regular rounds, together with influenza, RSV, and others. Due to this, there are a lot of extra alternatives this 12 months for viruses to contaminate non-immune people,” explains Roger Seheult, MD, a pulmonologist and medical advisor to Intrivo, and assistant scientific professor on the Faculty of Medication and Allied Well being at Loma Linda University in California.
“With little social distancing to cease the unfold of viruses, these beforehand contaminated and proof against RSV, similar to older youngsters and adults, haven’t had the chance [for] publicity over the last two years. This has prompted immunity to wane in a major proportion of the inhabitants,” he says.
So, individuals who have by no means had sure viruses (learn: infants and younger youngsters), and older individuals who haven’t had publicity in a few years are coming down with these viruses now—which is why it could appear to be you or your family members are getting sick continuously.
