Long-term problems in younger low-risk COVID-19 patients; flu shot may offer some protection

Young, healthy adults with COVID-19 who do not require hospitalization are still at risk for long-term health problems, Oxford University researchers found.At an average of 140 days after their symptoms began, 98% were still fatigued, 92% had heart and lung symptoms, 88% had muscle aches, 87% had breathlessness, 83% headaches, and 73%gastrointestinal symptoms.The researchers say their study, posted on Friday on medRxiv ahead of peer review, cannot prove the virus caused these later issues.
