Mild or moderate COVID-19 lasts about two weeks for most people. Some people experience lingering health problems even after the fever and cough go away. Long-term COVID can happen in people who have mild symptoms, although patients with more severe initial illness seem to be more likely to have it. It can take months for a person’s lung function to return to pre-COVID-19 levels. Some people with SARS-CoV-2 infection can have heart problems. The coronavirus can affect cells in the nose and can lead to distorted senses of smell or taste. Long-term cognitive impairment after coronavirus infection can have a severe impact on a person’s life. Post-intensive care syndrome puts COVID-19 survivors at a higher risk for problems with mental health, cognition, and physical recovery. Some people are left with lingering anxiety, depression, and other post-COVID mental health issues. Long-term COVID-19 symptoms can include fatigue, headaches, mood concerns, shortness of breath, and other long-hauler symptoms. Heart inflammation is a concern for young athletes returning to their sports after a mild or even asymptomatic case of the coronavirus.
