Return of the Coronavirus: 2019-nCoV 2020-01-24 .txt text/plain 3938 186 51 Similar to severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) infections, patients exhibited symptoms of viral pneumonia including fever, difficulty breathing, and bilateral lung infiltration in the most severe cases [1] . A range of disease has been observed highlighted by fever, dry cough, shortness of breath, and leukopenia; patients have included mild cases needing supportive care to severe cases requiring extracorporeal membrane oxygenation; however, compared to SARS-CoV (10% mortality) and MERS-CoV (35% mortality), the 2019-nCoV appears to be less virulent at this point with the exception of the elderly and those with underlying health conditions. In the early part of the outbreak, the absence of infection in health care workers argued for inefficient human to human spread and distinguished 2019-nCoV from both SARS-CoV and MERS-CoV. ./cache/cord-301633-t8s4s0wo.txt ./txt/cord-301633-t8s4s0wo.txt
