Uncertain recovery: The emerging long-term complications of Covid-19
At first, Lauren Nichols tried to explain away her symptoms. In early March, the healthy 32-year-old felt an intense burning sensation, like acid reflux, when she breathed. Embarrassed, she didn’t initially seek medical care. When her shortness of breath kept getting worse, her doctor tested her for Covid-19.
Her results came back positive. But for Nichols, that was just the beginning. Over the next eight weeks, she developed wide and varied symptoms, including extreme and chronic fatigue, diarrhea, nausea, tremors, headaches, difficulty concentrating, and short-term memory loss.
“The guidelines that were provided by the CDC [Centers for Disease Control and Prevention] were not appropriately capturing the symptoms that I was experiencing, which in turn meant that the medical community was unable to ‘validate’ my symptoms,” she says. “This became a vicious cycle of doubt, confusion, and loneliness.”
An estimated 40 to 45 percent of people with Covid-19 may be asymptomatic, and others will have a mild illness with no lasting symptoms. But Nichols is one of many Covid-19 patients who are finding their recovery takes far longer than the two weeks the World Health Organization says people with mild cases can expect. (The WHO says those with severe or critical cases can expect three to six weeks of recovery.)
Because Covid-19 is a new disease, there are no studies about its long-term trajectory for those with more severe symptoms; even the earliest patients to recover in China were only infected a few months ago. But doctors say the novel coronavirus can attach to human cells in many parts of the body and penetrate many major organs, including the heart, kidneys, brain, and even blood vessels.
“The difficulty is sorting out long-term consequences,” says Joseph Brennan, a cardiologist at the Yale School of Medicine. While some patients may fully recover, he and other experts worry others will suffer long-term damage, including lung scarring, heart damage, and neurological and mental health effects.
