Omicron amps up concerns about long COVID and its causes

Associated Press  

More than a year after a bout with COVID-19, Rebekah Hogan still suffers from severe brain fog, pain and fatigue that leave her unable to do her nursing job or handle household activities. In her lab at Stellenbosch University in South Africa, scientist Resia Pretorius has found microclots in blood samples from patients with COVID-19 and in those who later developed long COVID. Iwasaki, who is also an investigator with the Howard Hughes Medical Institute, which supports The Associated Press’ Health and Science Department, said she is doing this study because patient groups have reported improvement in some people’s long COVID symptoms after they got their shots. One thing’s for sure, some experts say: Long COVID will have a huge effect on individuals, health care systems and economies around the world, costing many billions of dollars. “Long COVID will probably have a more severe impact on our economy than acute COVID.” ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
