US research has found that one in 10 adults could experience long COVID after contracting the Omicron variant of the virus. The study also identified several key symptoms of long COVID, including extreme fatigue, brain fog, and shortness of breath. Additionally, researchers are investigating why some people develop long COVID, while others do not. The findings underscore the need for continued vigilance and caution around the virus, even as vaccination rates climb and hospitalization rates decrease. Health officials are urging people to get vaccinated, wear masks, and practice social distancing to help reduce the spread of the virus and prevent the development of long COVID.
