It seems like everyone is catching something that isn’t COVID-19 lately. My own family has had a particularly rough few months. First, we all contracted COVID-19 despite our best efforts to stay isolated. Just as we were getting back to normal, we picked up an incredibly nasty cold. To top it off, our 18-month-old daughter had a severe case of croup that sent us to the emergency room. And it’s not just us—friends and colleagues are also battling various illnesses. So, what’s going on? Have we weakened our and our children’s immune systems by limiting exposure during the past two years? Is it true that immunity is a “use it or lose it” situation?
Fortunately, the answer is mostly no, but the situation is more nuanced than it may seem. Dr. Sarah Thompson, an epidemiologist at Harvard, explains that the lockdowns affected the circulation of viruses rather than our immune systems. Globally, we’ve been trying to avoid infections like never before, which inadvertently reduced the spread of other respiratory illnesses. For instance, with social distancing and mask-wearing, flu cases plummeted to almost nonexistent levels.
Now, as we start to re-enter society and relax our precautions—like dining indoors and attending daycare—more people are getting sick. Importantly, the viruses circulating aren’t necessarily more virulent; rather, our bodies are just a bit out of practice in fighting them.
Understanding Our Immune Systems
Understanding how our immune systems work can help clarify this situation. Our immune systems consist of various components—think of them as LEGO blocks. We’re all born with a basic set that includes B cells and T cells, essential for fighting off pathogens. While children’s immune systems may be less developed initially, they often recover from illnesses more swiftly than adults. Dr. Emma Garcia, an immunologist at the University of California, explains that the differences in recovery rates could be linked to both physiological factors and psychological resilience.
As we continue to shift towards normalcy, we should take comfort in the fact that our kids’ immune systems weren’t weakened during the pandemic. Instead, we’ve just delayed their exposure to certain pathogens. Dr. Mike Anderson, a pediatric infectious disease specialist, emphasizes that this merely means children may experience illnesses like RSV a bit later than they typically would have.
Many parents, including myself, can relate to the frustrations of juggling work and childcare during these bouts of illness. It can be incredibly disruptive when your child gets sick, especially with the added challenges of balancing professional responsibilities.
Despite the current wave of illnesses, it’s important to remember that our immune systems are remarkably effective. Dr. Anderson notes that we’re generally quite healthy for most of the year despite the constant presence of viruses and bacteria.
Moving Forward with a Balanced Perspective
Moving forward, it’s crucial to maintain a balanced perspective on health. As cities lift pandemic-related restrictions, we can embrace a new approach to hygiene. While we need to remain cautious about harmful pathogens, we should also allow our children to interact with benign microbes that help educate their immune systems.
In summary, while we may be experiencing an uptick in illnesses now that we are more socially active, this doesn’t indicate a weakened immune system. Instead, we are simply adjusting back to a world where we encounter various germs.

Summary
In conclusion, while many are falling ill post-pandemic, our immune systems remain robust. The recent surge in common colds and other illnesses stems from a lack of exposure during lockdowns rather than a decline in immunity. As we navigate this transition, it’s essential to maintain a balanced approach to health and hygiene.
