Scientists at the University of California, San Francisco, United States of America, found extensive immune abnormalities in intestinal tissue taken from people with long Covid, including signs that some of the body’s first-line defenses remained activated months or years after infection. At the same time, processes needed to recognize and destroy virus-containing cells were weakened.
