A study published in March 2026 in Infection found that:
| Many healthcare workers still have symptoms years later – nearly 4 years after infection, around 6 in 10 still reported at least one symptom. |
| Fatigue, brain fog, and loss of smell or taste were the most common ongoing problems. |
| Symptoms generally improved over time, but for many people they did not go away completely. |
| In this study about 4 in 10 healthcare workers initially reported Long Covid symptoms. |
| People who said they had Long Covid tended to have more symptoms and a greater impact on daily life. |
| Even when symptoms were described as “mild”, they could still affect everyday activities over the long term. |
| Full recovery is not guaranteed, and some people continue to experience symptoms for years. |
Overall, this study suggests that Long Covid can persist for several years, particularly for healthcare workers.
