Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was reported at the end of 2019 as a worldwide health concern causing a pandemic of unusual viral pneumonia and many other organ damages,which was defined by the World Health Organization as coronavirus disease 2019(COVID-19).The pandemic is considered a significant threat to global public health till *** this review,we have summarized the lessons learnt during the emergence and spread of SARS-CoV-2,including its prototype and *** overall clinical features of variants of concern(VOC),heterogeneity in the clinical manifestations,radiology and pathology of COVID-19 patients are also discussed,along with advances in therapeutic agents.

Background The 2009 pandemic H1 N1 (pH1N1) influenza showed that relatively young adults accounted for the highest rates of hospital admission and *** preparation for pH1N1,the aim of the study is to identify factors associated with the mortality of patients with 2009 pH1N1 infection,especially for young patients without chronic medical *** Retrospective observational study of 2151 severe or critical adult cases (-≥14 years old) admitted to a hospital with pH1N1 influenza from September 1,2009 to December 31,2009 from 426 hospitals of 27 Chinese provinces.A confirmed case was a person whose pH1N1 virus infection was verified by real-time reverse-transcriptase polymerase chain reaction (rRT-PCR).Severe and critical cases were defined according to the H1N1 2009 Clinical guidelines (Third Edition,2009) released by the Ministry of Health of *** Among the 2151 patients,the mean age was 34.0 *** hundred and ninty-three (13.6%) died during hospital *** thousand four hundred and forty-two patients (67.0%) had no comorbidities and 189 (13.1%) of them *** (OR 8.03),pneumonia (OR 8.91),dyspnea (OR 3.95),central nervous system (CNS) symptom (OR 1.55),higher APACHE (Acute Physiology and Chronic Health Evaluation) Ⅱ score (OR 1.06),Alanine aminotransferase (ALT) (OR 1.002),and the lactate dehydrogenase (LDH) level (OR 1.001) were independent risk factors for death among adults without chronic medical *** APACHE Ⅱ score (OR 1.08) and age (OR 1.06) were independent risk factors for death among adults with respiratory diseases.A multivariate analysis showed an association between mortality and CNS symptoms (OR 2.66),higher APACHE Ⅱ score (OR 1.03),ALT (OR 1.006),and LDH level (OR 1.002) in patients with cardiovascular *** (OR 11.32) was an independent risk factor for patient death in patients with diabetes *** Clinical knowledge of identified prognostic factors for mortality may aid in the
