We conducted a systematic review of the included studies and a meta-analysis of the cohorts.</p> <p><strong>Results: </strong>We included 40 case reports, 14 case series and 12 cohort studies in this systematic review. Based on cohort studies, patients typically presented with a history of sick contact (46%, 95% CI 42-49) or recent travel (24%, 95% CI 11-37). Cough (79%, 95% CI 71-86%), fever (61%, 95% CI 40-81%) and shortness of breath (48%, 95% CI 36-61) were the most common chief complaints. Although rarely present in ED patients, decreased taste and smell significantly increase the probability of testing positive for COVID-19 (risk ratio 6.20; 95% CI 1.82-21.14). Several rare clinical presentations of COVID-19 include stroke and skin rashes. Gastrointestinal symptoms could be found in up to 10-20% of patients. Although initial vital signs were not different between those who tested positive and negative for COVID-19, the intubation rate in the ED was triple in those with COVID-19 (risk ratio 3.59; 95% CI 1.48-8.69). Notable investigations were lymphopenia (71%, 95% CI 64-78) and bilateral infiltration on chest X-ray (60%, 95% CI 57-63). </p> <p><strong>Conclusion: </strong>Patients with COVID-19 could present to EDs with typical respiratory symptoms as well as several unusual manifestations, including gastrointestinal, neurological and dermatological problems. Since the intubation rate tripled in those with COVID-19 compared to those without. Thus, emergency physicians should prepare for effective intubation while keeping patients and providers safe.</p>}, number={1}, journal={Thai Journal of Emergency Medicine}, author={Thonguthaisri, Witsanu and Musikatavorn, Khrongwong and Susantitaphong, Paweena and Saoraya, Jutamas}, year={2022}, month={Jul.}, pages={52–84} }
