December 10, 2020 – In February, when the world barely knew the name COVID-19, Marina Oshana had what she thought was the flu or some other bug.
āIām an avid Jazzerciser. I love to dance. I was working out five or six days a week,ā the UC Davis professor emerita of philosophy said on the Dec. 3 edition ofĀ UC Davis LIVE. āI noticed during the cardio portion of the class, I would get fatigued. It was very strange. It seemed to come on suddenly.ā
Her ābugā was SARS-CoV-2, the novel coronavirus, and her COVID-19 case was fairly middle-of-the-pack in terms of intensity. She had a āwicked sore throatā for a day, some exhaustion and about two weeks of a bad cough.
Then she was no longer a āmidpackā COVID-19 patient. Some symptoms never went away. Some new ones emerged. Nine months later, Oshana is still fighting fatigue and breathing issues, and her oxygen levels wobble up and down, frequently dropping into dangerous territory. Oshana has become what is being called a COVID-19 ālong-hauler.ā
āWhen Iām out walking, I definitely cannot keep up the pace,ā she said. āI can get out of breath almost immediately sometimes.ā
Christian Sandrock, a UC Davis Health professor of pulmonary and critical care medicine, said Oshana is both typical and atypical of long-haulers ā because their symptoms and the severities of the symptoms are enormously varied. And there is no playbook for who might become a long-hauler and how badly they might suffer.

āWeāve had some patients who were profoundly ill in our intensive care unit, then they recovered and had no other symptoms,ā Sandrock said. āAnd some patients will do fine at first and are never admitted to the hospital. Then they have these effects that last and last.ā
There are other frightening aspects, he said, including:
- Wide-ranging symptoms ā They include respiratory issues and fatigue, like what Oshana is experiencing. Other long-haulers may have a lasting cough, body aches, a continued loss of smell and taste, or ā maybe the most confounding ā what has been described as brain fog. Thatās when thinking clearly becomes hard. āSome patients may have one of these symptoms and some will have a combination,ā Sandrock said. āWe just donāt know why yet.ā
- No precise statistics ā Some studies estimate about 10 percent of COVID-19 patients have symptoms that wonāt go away, but Sandrock said heās also seen literature reporting upwards of 20 percent.
- How long is long? ā āUnfortunately,ā Sandrock said, āwe donāt know that, either.ā For some people, itās a few months. For others, like Oshana, they are still experiencing symptoms after nine months.
Post-COVID-19 Clinic
In response to the growing number of long-haul patients, UC Davis Health recently launched the regionās firstĀ Post-COVID-19 ClinicĀ to provide streamlined, comprehensive care from a range of expert specialists. Sandrock is among the physicians providing care for clinic patients.
āWeāre realizing itās a very multidisciplinary event,ā he said. āPatients need multiple specialists and they need a specialty clinic where everything theyāre dealing with can be evaluated and treated. It can be a scary thing and people need a place to go.ā
UC Davis Health is one of only a handful of health systems in the United States to create a clinic that cares for long-haul patients. UC Davis Health research is also connected with the clinic, with the goal of finding answers about the causes and the care needs of long-haul COVID-19 patients.
Useful lessons
Sandrock and Oshana said there are lessons for everyone from Oshanaās case, regardless of whether they have been a COVID-19 patient. It starts with taking health precautions seriously. For post-COVID-19 patients, donāt shrug off signs that your symptoms arenāt going away.
āAs you go about your daily life, like walking or riding your bike, if you notice there is something wrong or youāre not back to normal, go see your doctor,ā Sandrock said. āWe may be struggling with long-haulers in some ways, but there is still a lot we can do to help.ā
Oshana said she has found that walking and exercising is still crucial for her ā but at a reduced level. For her right now, going too hard can be as bad as doing nothing,
āFor people like me, we have to learn to dial back our expectations,ā Oshana said. āItās frustrating and humbling, so maybe take it as a lesson in humility. Do what you can. Listen to your body and not your ego.ā
The most important lesson, Oshana said, is that COVID-19 is dangerous for everyone.
āThere are people saying you just get over it,ā she said. āBut you might not get over it. I was not on a ventilator. I was not in the hospital. I was up and around and walking. It seemed like I would be fine, until the new symptoms cropped up.ā
And they kept coming. āI was first sick in February and it wasnāt until August that I developed chest pains and stitches in my side,ā Oshana said. āYou donāt want that to happen to you. Donāt be complacent. Do what doctors tell you to do ā wear a mask and keep your distance from people. You just donāt know what might happen.ā
