After the long sufferable weeks from catching COVID-19, you would think you are in the clear; until, that is, you feel some extra “health-issues”. The term for these health issues, specifically after COVID-19, are called Long Covid (post-covid). Generally “one in two [covid recovered people] experienced long-term COVID manifestations” and the symptoms included are a diverse field of sickness. Penn State investigators mentioned the trend of symptoms from 250,351 unvaccinated adults and children:
Loss of General Well Being (weight loss, fevers, fatigue)
Decreased Mobility (1 in 5 experienced a decrease in mobility)
Lung abnormalities (6 in 10 survivors tight chests and a quarter of patients had difficulty breathing)
What could be the reason that COVID-19 is still lurking around in our bodies when the sickness is gone? Researchers at Yale University studying long-COVID have found a pattern of patients having an “unusual level of cytokines” also known as a cytokine storm. Cytokines are a secreted chemical proteins released by cells for communication. In the Immune System process, after a Macrophage, large phagocytic cells, ingests an antigen it releases cytokines, signaling for a t-helper cell to come. After the helper t-cell recognizes the antigen, more cytokines are released and trigger the Cell-Mediated and Humoral Responses (B and T cells). I mention all this because researchers are saying that post-covid patients tend to have patterns of irregular, more-than average cytokines being produced as well as an “unusual pattern of activity by…t cells. The greater than average amount of cytokines suggests a “state of chronic inflammation” and “kill tissues and damage organs.” The unusual activity of t-cells suggests that COVID-19 could still be lurking in the body.
The treatment for these conditions are mostly to take the vaccine but there are still many unknowns to this Long-Covid problem. These problems are mostly lying in the Immune System rather than other parts of the body that can be tested with machines; which is why solving this problem is very difficult. This problem can only be solved by a matter of time and hope the scientists can figure this out.
