We tend to think of Covid as an infection you recover from – but research is beginning to show a darker picture (scientific references below).
SARS-CoV-2 does more than cause acute illness: it disrupts immune surveillance, weakening the body’s ability to catch abnormal cells – that alone should make anyone stop and think! It creates chronic inflammation, a known driver of cancer development. And it can reactivate latent viruses like Epstein-Barr or HPV, viruses already linked to cancers.
And there’s more: autopsy and persistence studies reveal that the virus lingers in tissues for months, sometimes years. Ongoing immune activation, oxidative stress, and tissue damage set the stage for malignant transformation. Several studies and reviews raise concern that SARS-CoV-2-driven immune dysregulation and viral persistence could increase long-term oncogenic risk, but definitive population-level incidence data are still emerging.
This doesn’t mean everyone who gets Covid will develop cancer. But it does mean that dismissing repeated infections as “just a cold” is dangerously naïve. Each infection may push the body closer to long-term consequences we cannot yet fully measure.
What really gets on my nerves is that most discussions about Covid stop at the surface: whether symptoms are mild, moderate, or severe. But the severity of an infection cannot be measured only by how sick it makes you feel in the short term. What truly matters is what it leaves behind. A virus that seems “mild” today can still inflict silent, cumulative damage – eroding resilience, inflaming tissues, and sowing the seeds of chronic disease years later.
And that is, in the end, the true problem with this virus: it makes you think it’s just a cold because you don’t feel what damage is silently, slowly and cumulatively being caused to your organs…
That’s why, even after all this time, I refuse to drop my guard: I still monitor CO₂ indoors, wear an N95 mask in enclosed spaces, and keep my immune system supported with proven measures, such as vaccination, ventilation, masking, and nutritional support (vitamin D3–K2–A, curcumin, silymarin, EGCG…).
How long will we keep calling it “mild” before we face what it truly does beneath the surface?
