Some viruses can reprogram your immune cells to stay inflamed for years

Advanced single-cell analysis shows that certain viruses act like genetic hackers, reprogramming the epigenetics of monocytes and T-cells. Instead of returning to a resting state after an infection clears, these cells remain stuck in pro-inflammatory loops due to specific histone modifications. This molecular shift affects up to ten percent of people after certain infections, explaining why fatigue and brain fog can persist for twelve months or longer.
