My hospital recently brought back mask mandates for staff interacting with patients. While patients are advised to wear masks, it’s not a strict rule. Thankfully, I still have a stash of N95 masks at home, so putting one on felt familiar. But honestly, it also brought back some uncomfortable memories. As much as I wish I didn’t have to wear a mask all day, it’s now just part of the job—like washing hands and keeping up with vaccines.
It seems many of us are still grappling with the impacts of COVID-19. Before the pandemic, we often felt safe, trusting that modern medicine would protect us from serious illnesses. We knew some people were vulnerable, but it rarely felt urgent. The pandemic changed that—it made everyone feel at risk and forced us to rethink how we live.
No one likes being reminded that COVID is still around, and some precautions are still necessary, albeit less intense. COVID has shifted from a pandemic to a background concern among other respiratory viruses like flu and RSV (respiratory syncytial virus). This makes it essential to manage health risks and take precautions seriously.
During the cold season, the chances of catching any respiratory virus rise. The impact of diseases like COVID can lead to hospitalizations, which can strain healthcare systems. According to the CDC, from October to November 2024, there were between 64,000 and 110,000 hospitalizations due to COVID-19. Even if COVID isn’t the focus of our daily lives, it still poses serious health risks.
We are learning more about how COVID is changing, especially with new variants. The Omicron variant and its subtypes continue to be the most common. Recently, a new XEC variant emerged from a mix of strains. While it can evade some immunity, it generally causes milder illness. Some people may mistake it for a common cold, which shows how unpredictable this virus can be.
One interesting way we track the spread of viruses is through wastewater. Scientists can analyze waste to detect the presence of virus particles, helping us keep tabs on infection levels. This method provides valuable insights into how viruses evolve and spread.
The emergence of the XEC variant teaches us that viruses will keep evolving. Staying informed about new strains is crucial for minimizing their spread. This means vaccines must be updated regularly, and people should continue to get booster shots. It’s becoming clear that an annual flu and COVID vaccine could become the norm, but participation has dropped significantly. The CDC reports only 11% of kids and 22.8% of adults have received the updated 2024-2025 COVID vaccine.
This decline is concerning because vaccines play a vital role in reducing the severity of illness. Many people have gained natural immunity from previous infections, but as the virus evolves, it’s essential to keep vaccinations up to date.
Moreover, these viruses can change in unexpected ways. For instance, COVID is becoming more like an upper respiratory pathogen than one causing severe lung infections. This shift is good news, but it’s not guaranteed. Viruses could evolve unpredictably, leading to new variants that might evade immunity or cause more severe illness.
We live in a world with over 8 billion people, all interconnected. This connectivity makes us vulnerable to various infectious agents. The constant presence of germs means that we’ll face new challenges continuously.
While our immune systems are our first line of defense, we also have tools to enhance that protection. By following the best scientific guidance and focusing on practical measures rather than politics, we can navigate this ongoing reality more effectively.
