The frequency of persistent symptoms after acute COVID-19 among Iraqi patients

Background: Post-coronavirus disease 2019 (COVID-19) symptoms tend to persist in many survivors of COVID-19. Objectives: To find out the prevalence of persistent symptoms that continue to appear after the eradication of the COVID-19 infection among Iraqi survivors. We hypothesized that wearing a mask during the COVID-19 pandemic may lead to a lesser viral load in an individual who gets infected, thereby leading to milder symptoms and manifestations. Materials and Methods: Overall, 70 consecutive Iraqi patients diagnosed with COVID-19 during the period from early August to late September 2020 were enrolled in the study, and on a mean of 31 days after recovery, they were assessed for persistent symptoms after the acute COVID-19 infection. Results: The mean age ± SD was 40.5 ± 16.1 years old. On a mean of 31 days post-COVID-19 recovery, 91.4% of all the patients had at least one persistent symptom. The most common persistent symptoms recorded were fatigue (42.9%), dyspnea (32.8%), and chest pain (25.7%). There was a statistically significant difference (P = 0.002) among patients with hypertension, among whom 45.5% had persistent palpitation. Among patients with ischemic heart disease, 25% had constant chest pain, and 37.5% complained of palpitation post-recovery. Patients who had used masks before infection (85.4%) were managed at home, and they did not require hospitalization. Overall, 45.7% of those dyspneic during the infection period were still complaining of exertional dyspnea post-recovery (P = 0.041). Conclusion: A large proportion of the Iraqi patients with COVID-19 infection had persistent symptoms after recovery. The use of a mask before infection showed mild symptoms during the acute phase, and hospitalization or oxygen therapy was not indicated for them.
