Millions worldwide continue to suffer from post-COVID-19 condition (PCC), commonly known as long COVID. PCC is characterized by symptoms lasting two months or longer after the acute phase of the infection, including dyspnea, fatigue, headache, autonomic dysfunction, and loss of taste and/or smell. A recent meta-analysis published online in JAMA Internal Medicine evaluated 41 studies to identify risk factors for PCC. They found that female sex, older age, being overweight, and smoking increased a person's risk. Certain comorbidities also increased risk, such as anxiety and depression, asthma, chronic obstructive lung disease, diabetes, ischemic heart disease, and immunosuppression. Patients sick enough to be hospitalized or admitted to an ICU were also more likely to develop PCC. Vaccination against COVID-19 significantly mitigated the risk; receiving at least two doses lowered PCC risk by 40%.
