Going long: Viruses linger with lasting impact'
'Herpes, HIV, Epstein-Barr and other viruses hang around, causing potential long-term health woes. Should long COVID surprise us?'
“We’re beginning to realize increasingly the long-term impacts of viruses, the infections that they cause and the damage that our immune system can wreak on us as a result of those infections” - Jim Boonyaratanakornkit, MD, PhD, a physician and infectious disease researcher at Fred Hutchinson Cancer Center in Seattle.
"Some believe EBV or other viruses may be responsible for myalgic encephalomyelitis or chronic fatigue syndrome, often referred to as ME/CFS..."
"Dr. Steve Pergam, medical director of infection prevention at Fred Hutch, called the long-term consequences of infections "a really intriguing space" for new research."
“There’s most definitely a lot to be learned about viruses still,” Boonyaratanakornkit said. “The hottest areas of research are EBV and long COVID.”
"NIH scientists are currently examining the similarities between long COVID and other post-viral fatigue ailments such as long-neglected ME/CFS."
“It’s not clear whether people with long COVID still have virus hiding in their body or if the virus is long gone but it’s tipped off an inflammatory cascade that doesn’t end when the virus goes away. Science is divided on this,” Bender Ignacio said. “We can’t rule out that there’s some persistent amount of virus in some people, but the vast majority who have long COVID, there isn’t virus. COVID-19 flipped the switch and left the building.”
"..Bender Ignacio calls “immune exhaustion.” "Exhausted cells, they’re not good at killing viruses,” she said. “They’re pooped out; their T cells have immune exhaustion."
"Pergam points to a flurry of interest in viral research and the body’s immune system as a silver lining. “Long COVID has provided us with a really robust opportunity to better understand this space,” he said.
'The National Institutes of Health’s RECOVER Initiative (Researching COVID to Enhance Recovery) has a number of long COVID studies running; Fred Hutch’s CCRC is also researching long COVID therapies.'
