Many Cases Including One of Yours Are Being Reviewed
(SACRAMENTO)
More than one in four COVID-19 patients develop long-haul symptoms lasting for months – even if they had mild cases, according to a scattering of studies that take emerged recently.
Doctors have been estimating one-quarter to one-third of COVID-xix patients become long haulers, as many patients phone call themselves. At present, four studies published since February confirm that range. They show that 27% to well-nigh 33% of patients who had COVID-19 but did not need to be hospitalized later developed some form of long-haul COVID.
"Those numbers are in line with what nosotros've seen," said Christian Sandrock, a UC Davis Health professor of pulmonary and disquisitional care medicine. "What'due south practiced about these studies is they help our patients. We tin can say, 'You're not alone. What you're going through is starting to be defined.'"
Another consistent finding is that information technology does non appear to matter whether not-hospitalized patients had more severe cases of COVID-nineteen, mild cases or even cases that acquired no symptoms at all.
Just every bit consistently, age or prior health – whether people were active and fit or had some previous health bug like diabetes or respiratory issues – made but a very small deviation, if any, amid non-hospitalized patients.
"Obesity and diabetes stand out as take chances factors that can make COVID-xix very serious and require hospitalization. They besides increment the risk for those hospitalized patients to develop post-COVID symptoms," said Sandrock, who works with the UC Davis Health Post-COVID-19 Clinic. "But among outpatients, chance factors fabricated very trivial divergence in the study numbers. That'due south also what we're seeing. Anyone can become long-haul COVID."
Even the mildest cases can cause long-haul COVID
The largest report is in preprint, pregnant it is nevertheless being peer reviewed. Researchers examined the medical records of i,407 people seen at a range of University of California outpatient clinics and found that 27% of those patients suffered from shortness of jiff, chest pains, coughs or intestinal hurting two months after existence sick with COVID-xix – and that well-nigh a third of those patients had no symptoms during their original infection.
"Among outpatients, hazard factors fabricated very footling deviation in the written report numbers. That's also what we're seeing. Anyone can get long-haul COVID."

A study from the University of Washington published in February found that 32.vii% of COVID-xix outpatients developed long-haul symptoms and 31.iii% of hospitalized patients became long haulers.
The difficulty with defining long-haul COVID-19 for patients who were hospitalized, however, is that many patients who spend time in intensive care for almost any reason – heart attack, trauma, flu and more – ofttimes take months to recover from both their disease and some of the ICU procedures that kept them alive.
"What's so unusual is to see a large grouping of people who seemed to have less severe cases have such long-lasting symptoms," Sandrock said. "This is not something we've seen with whatever other infectious disease."
Researchers are also defining the most mutual symptoms for long haulers. A Stanford Wellness Intendance written report of non-hospitalized COVID-19 patients published in the journal Clinical Infectious Diseases, and a report at New York City's Icahn Schoolhouse of Medicine at Mount Sinai both establish that fatigue and respiratory problems are the most mutual symptoms, followed past a mix of other problems including what's being called "brain fog," body aches and muscle hurting, abdominal issues and loss of smell and taste.
"Fatigue and shortness of jiff is what nosotros see the most," Sandrock said. "Simply 1 of the things about Mail service-COVID is that everybody seems to react differently."
More studies are coming to learn more about the symptoms and what's causing them – currently in that location are not even whatever widely embraced theories. The National Institutes of Wellness put out a proposal recently for a large national study.
"They're trying to assistance answer questions about what is happening with these people and how we can aid them more than," Sandrock said. "In our Post-COVID clinic, we've seen 130 to 140 patients now. Although this is withal very new, we're all developing some experience and collecting some information that can help usa offer our patients more assist."
With that experience, Sandrock said, doctors now know that some patients with long-haul COVID will make progress, although information technology's painfully slow.
"From the pattern we've seen so far, nosotros tin can say some patients don't get better only many do, although the pace is glacial," he said. "We tell people not to look dorsum day to day or even week to week, but they can run across they're improving month to month. Right now, that is at least something and nosotros hope we volition learn more soon."
