Long Covid, the phenomenon of experiencing symptoms of the coronavirus lasting for an extended period of time, has been the subject of a new study that identifies risk factors for this condition. Researchers analyzed the records of over 4,000 US adults who contracted the virus between April 2020 and February 2023. They found that about one in five individuals still had symptoms after three months, with women and those with cardiovascular diseases being more at risk for Long Covid. Interestingly, those who were vaccinated or infected with earlier versions of the omicron strain were less likely to experience prolonged symptoms.
Dr. Elizabeth Olsner, an epidemiologist at Columbia University Irving Medical Center, emphasized the important role that the corona vaccine plays in reducing the severity of the infection and the risk of long-term Covid. While certain health conditions like chronic obstructive pulmonary disease were associated with longer recovery times, mental health problems were not found to be significant risk factors in this study.
Long Covid is characterized by symptoms lasting more than 12 weeks and varying in intensity. Over 200 possible symptoms have been reported, ranging from cough and fatigue to skin rashes and diarrhea. The disease is believed to be caused by inflammatory processes triggered by the corona virus, leading to issues like the “cytokine storm” that can cause extensive damage in the body. Treatment for Long Covid focuses on managing individual symptoms, such as physical therapy for lung damage and pharmacological and psychological interventions for mental disorders.
While there is currently no cure for chronic corona, understanding the risk factors associated with the condition can help in identifying and supporting those who may be at risk for prolonged illness in the future. By addressing these factors, researchers hope to shorten the duration and reduce the impact of Long Covid on individuals’ quality of life.
