COVID-19 has a lasting impact on the immune system, with studies showing that the virus can disrupt immune responses even after the initial infection. Unlike what occurs with many viral infections, natural immunity from COVID-19 doesn’t fully prevent reinfection or immune system suppression. Instead, research suggests that COVID-19 can cause immune dysregulation, leaving individuals more vulnerable to other infections and health complications. Emerging evidence also indicates that COVID-19 causes epigenetic changes in immune cells, potentially leading to long-term health impacts similar to those seen in conditions like HIV and Lyme disease. These changes could reduce both life expectancy and quality of life by increasing susceptibility to chronic health issues.
For example, studies have shown persistent immune activation and inflammation in post-COVID patients, which can contribute to conditions like cardiovascular disease and autoimmune disorders.
