Lately, it seems like illness is everywhere. My family has been through quite a whirlwind in the past few months. First, despite our best efforts to stay isolated, we contracted COVID-19. Just as we were starting to recover, we caught an awful cold — the worst I’ve had in ages. Recently, our toddler experienced a severe case of croup that landed us in the emergency room. It’s not just us; many friends and colleagues report battling unpleasant ailments as well. So, what’s going on? Have we inadvertently weakened our immune systems due to the pandemic precautions? Is immunity truly a matter of “use it or lose it”?
Fortunately, the answer is a bit more nuanced. According to Dr. Sarah Johnson, an epidemiologist from the University of California, the lockdown primarily affected the spread of viruses rather than our immune systems. The global effort to curb COVID-19 led to effective measures like handwashing, masking, and social distancing, which also minimized other respiratory infections.
With many of us now returning to a more social lifestyle after a long period of isolation, it’s not surprising to see an uptick in illnesses. Our immune systems may simply be out of practice when it comes to battling these common germs.
To understand how our immune system works, it’s helpful to think of it like a set of LEGO blocks. We’re all born with a basic set of immune “blocks,” which include B cells, T cells, and antibodies. As we grow, exposure to various pathogens helps us build on that set, teaching our immune system how to defend against different illnesses. Interestingly, while children may start with fewer “blocks,” they often recover more quickly from illnesses than adults. This could be due to a mix of resilience, inflammation responses, and even psychological factors.
So, what does this mean for us now? We can breathe a sigh of relief knowing our kids’ immune systems weren’t weakened during the pandemic; instead, they just faced fewer bugs for a while. As we all re-enter social settings, it’s likely that our bodies are just adjusting to these exposures again.
Dr. Mark Thompson, a pediatric infectious disease specialist, relates to the frustration parents feel as they navigate this resurgence in colds and flus. His own family has recently eased up on precautions, resulting in their share of illness too.
It’s undeniable that illness can disrupt our lives, especially when it comes to balancing work and childcare. Many parents are experiencing this struggle, with the added challenge of remote work creating a blurred line between personal and professional responsibilities.
While it’s easy to feel overwhelmed, we should remember that our immune systems are quite effective at handling pathogens. Dr. Thompson points out that despite the constant presence of viruses and bacteria, we generally remain healthy throughout the year.
As we move forward, particularly with the easing of pandemic restrictions, we should continue to be mindful of hygiene and illness prevention. There’s an opportunity to foster new norms around staying home when sick and being more considerate of our health and the health of those around us.

In summary, while it may feel like everyone is falling ill, this is largely due to our return to social interactions after a long period of isolation. Our immune systems are simply readjusting to the pathogens around us. Embracing new health norms and being mindful of hygiene will help us navigate this transitional phase.
