    No systematic data on hospitalized SARS-COV-2 patients from Western countries are available. We report onset, course, correlations with comorbidities, and diagnostic accuracy of nasopharyngeal swab in 539 individuals suspected to carry SARS-COV-2 admitted to the hospital of Crema, Italy. All individuals underwent clinical and laboratory exams, SARS-COV-2 reverse transcriptase-polymerase chain reaction on nasopharyngeal swab, and chest X-ray and/or computed tomography (CT). Data on onset, course, comorbidities, number of drugs including angiotensin converting enzyme (ACE) inhibitors and angiotensin-II-receptor antagonists (sartans), follow-up swab, pharmacological treatments, non-invasive respiratory support, ICU admission, and deaths MESHD were recorded. Among 411 SARS-COV-2 patients (66.6% males TRANS) median age TRANS was 70.5 years (range 1-99). Chest CT was performed in 317 (77.2%) and showed interstitial pneumonia MESHD pneumonia HP in 304 (96%). Fatality rate was 17.5% (74% males TRANS), with 6.6% in 60-69 years old, 21.1% in 70-79 years old, 38.8% in 80-89 years old, and 83.3% above 90 years. No death MESHD occurred below 60 years. Non-invasive respiratory support rate was 27.2% and ICU admission 6.8%. Older age TRANS, cough MESHD cough HP and dyspnea MESHD dyspnea HP at onset, hypertension MESHD hypertension HP, cardiovascular diseases MESHD, diabetes, renal insufficiency MESHD renal insufficiency HP, >7 drugs intake and positive X-ray, low lymphocyte count, high C-reactive protein, aspartate aminotransferase and lactate dehydrogenase values, and low PO2 partial pressure with high lactate at arterial blood SERO gas analysis at admission were significantly associated with death MESHD. Use of ACE inhibitors or sartans was not associated with outcomes. Comorbidity network analysis revealed homogenous distribution of deceased and 60-80 aged TRANS SARS-COV-2 patients across diseases MESHD. Among 128 swab negative patients at admission (63.3% males TRANS) median age TRANS was 67.7 years (range 1-98). Chest CT was performed in 87 (68%) and showed interstitial pneumonia MESHD pneumonia HP in 76 (87.3%). Follow-up swab turned positive in 13 of 32 patients. Using chest CT at admission as gold standard on the entire study population of 539 patients, nasopharyngeal swab had 80% sensitivity SERO. SARS-CoV-2 caused high mortality among patients older than 60 years and correlated with pre-existing multiorgan impairment. ACE inhibitors and sartans did not influence patients' outcome.

    Abstract Background:There is currently a global outbreak of coronavirus disease MESHD 2019 (COVID-19),and its epidemic characteristics in the areas where the outbreak has been successfully controlled are rarely reported. Objective: Describe the epidemic characteristics of COVID-19 in Jingmen,Hubei,introduce the local prevention and control experience,and observe the impact of various prevention and control measures on the number of new cases. Methods: All the COVID-19 patients diagnosed in the municipal districts of Jingmen from January 12 to February 29,2020 were enrolled in this study. We described epidemiological data and observed the impact of control measures on the epidemic. Findings: Of the 219 cases (110 men and 109 women), 88 (40%) had exposure to Wuhan. The median age TRANS was 48 years ( range,2-88 years;IQR,35-60). Thirty-three severe patients with a median age TRANS of 66 years(range,33-82 years,IQR,57-76) were treated in intensive care units; out of these patients, 66.7 %(22) were men and 19 (57.5%) had chronic diseases MESHD, including hypertension MESHD hypertension HP, diabetes, heart failure MESHD, stroke MESHD stroke HP, and renal insufficiency MESHD renal insufficiency HP. Under the control measures, the number of new patients gradually decreased and nearly disappeared after 18 days. Wearing masks in all kinds of situations prevents most infections MESHD and is one of the most effective prevention and control measures. Interpretation: In conclusion,all people are susceptible to COVID-19, and older males TRANS and those with comorbid conditions are more likely to become severe cases. Even though COVID-19 is highly contagious,control measures have proven to be very effective, particularly wearing masks,which could prevent most infections MESHD.
