Can Chinese Medicine Be Used for Prevention of Corona Virus Disease 2019 (COVID-19)? A Review of Historical Classics, Research Evidence and Current Prevention Programs
Hui and colleagues conducted a review of the literature on the use of Chinese medicine for the prevention and treatment of SARS and H1N1, including 7 studies overall. The most commonly used herbal treatments are described along with the results of these studies which generally indicated protective effects of these treatments. Recommendations for future testing…
The Epidemiological Characteristics of an Outbreak of 2019 Novel Coronavirus Diseases (COVID-19) — China, 2020
China CDC has published descriptive clinical information for 72,314 patients, including 44,672 confirmed, 16,186 suspected, and 10,567 clinically diagnosed, and 889 asymptomatic cases of COVID-19. 1,023 deaths occurred among confirmed cases (2.3%). The article includes descriptive information of cases and multiple epidemic curves, showing a peak in symptom onset in Hubei from Jan 23-26. China…
Molecular and serological investigation of 2019-nCoV infected patients: implication of multiple shedding routes
Biological samples taken from 15 COVID-19 patients in one Chinese hospital were tested for the presence of 2019-nCoV. Oral samples tested positive in only half of patients, 4 had positive anal swabs, 6 had positive blood samples, and 3 were also serum positive. A second analysis suggests that oral swabs tend to test positive more…
Longitudinal characteristics of lymphocyte responses and cytokine profiles in the peripheral blood of SARS-CoV-2 infected patients
Peripheral blood samples were collected longitudinally from 40 confirmed COVID-19 cases and evaluated for lymphocyte subsets and cytokine profiles. Severe cases had more sustained lymphocyte depletion but increased neutrophil counts compared to mild cases. T cell counts were also decreased among severe cases. The neutrophil-to-CD8+ T cell ratio may be a useful prognostic tool for…
Preparing for the Most Critically Ill Patients with COVID-19: The Potential Role of Extracorporeal Membrane Oxygenation
This commentary offers considerations for the role that ECMO should play in treatment for severe cases of COVID-19. MacLaren et al. (Feb 19, 2020).

Assessing the Tendency of 2019-nCoV (COVID-19) Outbreak in China
Liu et al. estimate the temporal trends of the outbreak, focusing on peak windows in Hubei Province and other parts of China. Unlike Peng et al., this paper suggests that peak case counts will not be reached until March. Liu et al. (Feb 18, 2020). Assessing the Tendency of 2019-nCoV (COVID-19) Outbreak in China. Pre-print…
Epidemic analysis of COVID-19 in China by dynamical modeling
Using public national data out of China, researchers attempted to predict the trajectory of the outbreak, estimating optimistically that the outbreak would be over by the end of February in Beijing and Shanghai and in the rest of mainland China by mid-march. The outbreak in Wuhan was estimated to end in early April. As always,…
Evaluating new evidence in the early dynamics of the novel coronavirus COVID-19 outbreak in Wuhan, China with real time domestic traffic and potential asymptomatic transmissions
Using information from evacuees from Wuhan and domestic traffic, authors explore the early dynamics of the COVID-19 outbreak and the potential role of asymptomatic transmission. The study did not find strong evidence of asymptomatic transmission but does not rule it out. Additional model findings are described. Zhou (Feb 18, 2020). Evaluating new evidence in the…
Estimating the Case Fatality Risk of COVID-19 using Cases from Outside China
Using data for symptomatic COVID-19 cases occurring outside of China and in countries with 20+ cases, researchers estimated the case fatality risk for COVID-19 cases outside of China to be about 1.4% (95% CI: 0.57%-3.22%) Wilson et al. (Feb 18, 2020). Estimating the Case Fatality Risk of COVID-19 using Cases from Outside China. Pre-print downloaded…
