Those suffering from post-acute sequelae of COVID-19 frequently have difficulty concentrating and memory problems, sometimes called “brain fog.” This impairment is a common symptom in those with severe fatigue of any cause.
For most people, the symptoms end with a cough and a fever. More than 8 in 10 cases are mild. But for some, the infection gets more severe.
About 5 to 8 days after symptoms begin, they have shortness of breath (known as dyspnea). Acute respiratory distress syndrome (ARDS) begins a few days later.
COVID-19 can cause lasting damage to multiple organs, including the lungs, heart, kidneys, liver and brain. SARS CoV-2 first affects the lungs through the nasal passages. When the lungs are severely affected, it can affect the heart.
Benefits of Vaccination Outweigh the Risks Serious side effects that could cause a long-term health problem are extremely unusual following any vaccination, including COVID-19 vaccination.
"Some symptoms of COVID-19 linger longer than others," says Dr. Septimus. "In particular, fatigue and loss of taste and smell can persist beyond the period of contagion."
While uncomfortable and/or inconvenient, Dr. Septimus adds that these lingering symptoms aren't too worrisome for most people.
“Acute” respiratory illness is an infection of the upper or lower respiratory tract that may interfere with normal breathing, such as COVID-19. “Acute” means of recent onset (for example, for a few days), and is used to distinguish from chronic respiratory illnesses like asthma and chronic obstructive pulmonary disease (COPD).
Lungs are the main organs affected by COVID-19; however, the virus can also affect other organs, such as the kidneys, brain, and liver. Lungs are the main organs affected by COVID-19.
