Health agency review found that half of COVID-19 patients report symptoms after 12 weeks


A new review by the Public Health Agency of Canada stated that more than half of COVID-19 patients may develop “post-COVID-19 syndrome” for more than three months after testing positive.

The review looked at more than two dozen studies from around the world that required confirmed COVID-19 patients to report at least one long-term symptom.

Preliminary findings indicate that eight in ten people experience at least one long-term symptom within 4 to 12 weeks after diagnosis, and more than half report that symptoms persist after 12 weeks.

Fatigue, pain, shortness of breath and sleep disturbance are the most common problems, followed by anxiety, coughing and hair loss.

Chief Public Health Officer Dr. Theresa Tam said in a statement that although most people will fully recover from COVID-19 within a few weeks, the so-called “long-term COVID-19” will affect people of all ages—no matter what they are. How seriously ill at the beginning.

The study pointed out that there are some potential weaknesses in the data due to self-reporting of the condition, the bias of the patients who choose to participate in the study, and the lack of understanding of the diseases that patients may have before contracting COVID-19.
