“…However, case-control studies and cohort studies are necessary to define the clinical evolution of disease better. A second stage, as occurs in SARS, is maybe also seen in COVID-19, with the lower respiratory tract bilateral compromise, observed in more than 72% of the patients across nine studies with more than 500 patients, also experiencing a dry cough, and dyspnea [5,48,52] and with chest X-ray images of ground-glass opacity frequently observed in two-thirds of patients -this is also seen in SARS [53].…”

Methods:We performed a systematic literature review with meta-analysis, using three databases to assess clinical, laboratory, imaging features, and outcomes of COVID-19 confirmed cases. Observational studies and also case reports, were included, and analyzed separately. We performed a random-effects model meta-analysis to calculate the pooled prevalence and 95% confidence interval (95%CI).Results: 660 articles were retrieved for the time frame (1/1/2020-2/23/2020). After screening, 27 articles were selected for full-text assessment, 19 being finally included for qualitative and quantitative analyses. Additionally, 39 case report articles were included and analyzed separately. For 656 patients, fever (88.7%, 95%CI 84.5-92.9%), cough (57.6%, 40.8-74.4%) and dyspnea (45.6%, 10.9-80.4%) were the most prevalent manifestations. Among the patients, 20.3% (95%CI 10.0-30.6%) required intensive care unit (ICU), 32.8% presented with acute respiratory distress syndrome (ARDS) (95%CI 13.7-51.8), 6.2% (95%CI 3.1-9.3) with shock. Some 13.9% (95%CI 6.2-21.5%) of hospitalized patients had fatal outcomes (case fatality rate, CFR).Conclusion: COVID-19 brings a huge burden to healthcare facilities, especially in patients with comorbidities. ICU was required for approximately 20% of polymorbid, COVID-19 infected patients and hospitalization was associated with a CFR of over 13%. As this virus spreads globally, countries need to urgently prepare human resources, infrastructure and facilities to treat severe COVID-19.

“…This method is not only limited to entrying population detection, but also can be used in community poplation detection and close contact population detection [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] .…”

Objective: To screen out COVID-19 patients in entrying population from abroad with the minimum number of nucleic acid testing (NAT). Methods:In the first stage, the nasopharyngeal swab samples of the entrying population are numbered and grouped. After the samples in the group are mixed together, one NAT was performed.When the test result is negative, it shows that all of the peple in the group are not infected and the test for the group is complete. On the contrary, when the test result is positive, the group enters the second stage. In the second stage, all samples in the positive group will be tested one by one using the NAT. Results:The advantages and precautions of the method were discussed. The incidence rate of entrying population is the determinant of the number of samples in the group. The lower the incidence rate, the larger the number of samples in the group, and the greater the percentage saved. Conclusion:The method has obvious efficiency and cost advantages in COVID-19 testing. It can also be used to screen other populations such as community populations, high risk of infection populations.
