Severe acute respiratory syndrome coronavirus 2 viral load in the upper respiratory tract peaks around symptom onset and infectious virus persists for 10 days in mild-to-moderate coronavirus disease (n = 324 samples analysed). RT-PCR cycle threshold (Ct) values correlate strongly with cultivable virus. Probability of culturing virus declines to 8% in samples with Ct > 35 and to 6% 10 days after onset; it is similar in asymptomatic and symptomatic persons. Asymptomatic persons represent a source of transmissible virus.

Case ReportsSevere acute respiratory distress syndrome in coronavirus disease 2019-infected pregnancy: obstetric and intensive care considerations.
Since the emergence of a novel coronavirus (severe acute respiratory syndrome coronavirus 2) in Wuhan, China, at the end of December 2019, coronavirus disease 2019 has been associated with severe morbidity and mortality and has left world governments, healthcare systems, and providers caring for vulnerable populations, such as pregnant women, wrestling with the optimal management strategy. Unique physiologic and ethical considerations negate a one-size-fits-all approach when caring for critically ill pregnant women with coronavirus disease 2019, and few resources exist to guide the multidisciplinary team through decisions regarding optimal maternal-fetal surveillance, intensive care procedures, and delivery timing. We present a case of rapid clinical decompensation and development of severe acute respiratory distress syndrome in a woman at 31 weeks' gestation to highlight these unique considerations and present an algorithmic approach to the diagnosis and management of the disease.

Coronavirus disease 2019 (COVID-19) is now of global concern due to its rapid dissemination across the globe. The rapid spread of this viral infection, along with many of its unknown aspects, has posed new challenges to the health care systems. The main challenging effects of COVID-19 are rapid dissemination through close contact and varying clinical severity among different individuals. ⋯ Also, due to the variable pulmonary manifestations of COVID-19, some physicians may misdiagnose patients. To overcome these issues, we proposed a web-based software to aid physicians in detecting possible COVID-19 cases through online consultation with different specialists and educate the not-well experienced physicians. Our results demonstrated that this software could improve the diagnostic rate for not-well experienced physicians.
