Eligibility included admission to the hospital, a laboratory-confirmed diagnosis of SARS-CoV-2 infection, and no need for intubation or intensive care at admission. The median (interquartile range) ages of patients who received hydroxychloroquine (n = 188 ) and those who did not (n = 148) were 68 (58-82) and 64 (51-73) years, respectively. In a multivariable model that included age, gender, obesity, diabetes, and hydroxychloroquine use, patients who received hydroxychloroquine were significantly more likely than those not treated with the drug to be transferred to an ICU (odds ratio, [OR], 8.1; 95% confidence interval [CI]: 3.8-17) and significantly more likely to be intubated (OR, 7.99; 95% CI, 3.76-16.91); these associations were not influenced by disease severity. In-hospital mortality did not differ significantly with disease severity between those who did and those who did not receive hydroxychloroquine.ConclusionHydroxychloroquine use was significantly associated with increased risks of ICU admission and intubation in patients with mild, moderate, and severe symptoms of COVID-19. There were no significant between-group differences in mortality with use vs nonuse of hydroxychloroquine.

Early Antiandrogen Therapy With Dutasteride Reduces Viral Shedding, Inflammatory Responses, and Time-to-Remission in Males With COVID-19: A Randomized, Double-Blind, Placebo-Controlled Interventional Trial (EAT-DUTA AndroCoV Trial - Biochemical).

Background and objectiveSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cell entry and subsequent infectivity are mediated by androgens and the androgen receptors through the regulation of transmembrane protease, serine 2 (TMPRSS2). Androgenetic alopecia (AGA) predisposes males to severe coronavirus disease 2019 (COVID-19) disease, while the use of 5-alpha-reductase inhibitors (5ARis) and androgen receptor antagonists reduce COVID-19 disease severity. In this study, we aimed to determine the potential benefit of dutasteride, a commonly used broad and potent 5ARi, as a treatment for COVID-19.Design, setting, and participantsThe study was conducted at outpatient clinics. Subjects presented to the clinics with a positive reverse transcription-polymerase chain reaction (RT-PCR) test taken within 24 hours of recruitment. All subjects presented with mild to moderate symptoms.InterventionsSubjects were given either dutasteride 0.5 mg/day or placebo for 30 days or until full COVID-19 remission. All subjects received standard therapy with nitazoxanide 500 mg twice a day for six days and azithromycin 500 mg/day for five days.Main outcome(s) and measure(s)The main outcome(s) and measure(s) were as follows: time to remission, oxygen saturation (%), positivity rates of RT-PCR-SARS-CoV-2, and biochemical analysis [ultrasensitive C-reactive protein (usCRP), D-dimer, lactate, lactate dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), ultrasensitive troponin, and ferritin].ResultsSubjects taking dutasteride (n=43) demonstrated reduced fatigue, anosmia, and overall disease duration compared to subjects taking a placebo (n=44) (p<.0001 for all). Compared to the placebo group, on Day seven, subjects taking dutasteride had a higher virologic remission rate (64.3% versus 11.8%; p=.0094), higher clinical recovery rate (84.7% versus 57.5%; p=.03), higher mean [standard deviation: SD] oxygen saturation (97.0% [1.4%] versus 95.7% [2.0%]; p=.02), lower median [Interquartile range: IQR] usCRP (0.34 mg/L [0.23 mg/L-0.66 mg/L] versus 1.47 mg/L [0.70 mg/L-3.37 mg/L]; p<.0001), lower median [IQR] lactate (2.01 mmol/L [1.12 mmol/L-2.43 mmol/L] versus 2.66 mmol/L [2.05 mmol/L-3.55 mmol/L]; p=.0049), lower median [IQR] ESR (5.0 mm/1h [3.0 mm/1h-11.0 mm/1h] versus 14.0 mm/1h [7.25 mm/1h-18.5 mm/1h]; p=.0007), lower median [IQR] LDH (165 U/L [144 U/L-198 U/L] versus 210 U/L [179 U/L-249 U/L]; p=.0013) and lower median [IQR] troponin levels (0.005 ng/mL [0.003 ng/mL-0.009 ng/mL] versus 0.007 ng/mL [0.006 ng/mL-0.010 ng/mL]; p=.048).Conclusions and relevanceThe findings from this study suggest that in males with mild COVID-19 symptoms undergoing early therapy with nitazoxanide and azithromycin, treatment with dutasteride reduces viral shedding and inflammatory markers compared to males treated with a placebo.

Coronavirus Disease 2019 Associated Risk Score, Behavior, and Symptom Prevalence in German Transplant Recipients

BackgroundTransplant recipients are prone to developing severe infections because of immunosuppression. Therefore, studying the manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in transplant recipients is of particular importance. MethodsOne hundred twelve transplant patients consecutively visiting the outpatient department of 2 German transplant centers were included in this study after providing written informed consent. The patients were interviewed about coronavirus disease 2019 (COVID-19) symptoms and history. Nasopharyngeal swabs were analyzed by SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR). SARS-CoV-2 IgG and IgA were measured concomitantly in patient sera by enzyme-linked immunosorbent assay. ResultsThe risk of severe COVID-19 according to 2 recent scores differed among the analyzed patients. All patients were well educated about their presumed higher risk of a severe COVID-19 and described performing self-isolation wherever possible. Nevertheless, 20 patients reported contact with someone suspected of having COVID-19 or who tested positive shortly thereafter (18%). Despite this relatively high exposure, no clinically relevant case of COVID-19 was reported. Though SARS-CoV-2 IgG and IgA were found in 3 patients (3%); 2 patients were asymptomatic and only 1 had mild COVID-19 symptoms and positive RT-PCR 4 weeks earlier. There were no occult SARS-CoV-2 infections, as demonstrated by negative PCR tests. ConclusionDespite the high exposure level, the incidence of COVID-19 remained very low. Because of the differences in COVID-19 risk, balancing risk exposure and quality of life should be recommended.

Screening and Testing Pregnant Patients for SARS-CoV-2: First-Wave Experience of a Designated COVID-19 Hospitalization Centre in Montréal.

ObjectiveCoronavirus disease 2019 (COVID-19) may present asymptomatically in a large proportion of cases in endemic areas. Accordingly, universal testing has been suggested as a potential strategy for reducing transmission in the obstetrical setting. We describe the clinical characteristics of patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy at a designated COVID-19 hospitalization centre in Montréal, Québec.MethodsA single-centre retrospective cohort was constructed to include all pregnant patients who tested positive for SARS-CoV-2 between March 22 and July 31, 2020, and received care at the Jewish General Hospital. Initially, testing was restricted to at-risk patients, identified through the use of a screening questionnaire. Beginning on May 15, 2020, universal testing was implemented, and all pregnant patients admitted to the hospital were tested. Data were collected through chart review.ResultsOf 803 patients tested for SARS-CoV-2 during the study period, 41 (5%) tested positive. Among those patients who were symptomatic, the most commonly reported symptoms were cough (53%), fever (37%), dyspnea (30%), and anosmia and/or ageusia (20%). Before the implementation of universal testing, 13% (3 of 24) of patients with SARS-CoV-2 were asymptomatic. After implementation of universal testing, 80% (8 of 10) of patients with SARS-CoV-2 were asymptomatic.ConclusionOur findings suggest that most pregnant patients with SARS-CoV-2 are asymptomatic or have mild symptoms of COVID-19. Particularly in endemic areas, universal testing of pregnant patients presenting to the hospital should be strongly considered as an important measure to prevent in-hospital and community transmission of COVID-19.

Understanding the Psychological Impact of COVID-19 Pandemic on Patients With Cancer, Their Caregivers, and Health Care Workers in Singapore.

PURPOSEThe coronavirus disease 2019 (COVID-19) pandemic has had a global impact, and Singapore has seen 33,000 confirmed cases. Patients with cancer, their caregivers, and health care workers (HCWs) need to balance the challenges associated with COVID-19 while ensuring that cancer care is not compromised. This study aimed to evaluate the psychological effect of COVID-19 on these groups and the prevalence of burnout among HCWs.METHODSA cross-sectional survey of patients, caregivers, and HCWs at the National Cancer Centre Singapore was performed over 17 days during the lockdown. The Generalized Anxiety Disorder-7 and Maslach Burnout Inventory were used to assess for anxiety and burnout, respectively. Self-reported fears related to COVID-19 were collected.RESULTSA total of 624 patients, 408 caregivers, and 421 HCWs participated in the study, with a response rate of 84%, 88%, and 92% respectively. Sixty-six percent of patients, 72.8% of caregivers, and 41.6% of HCWs reported a high level of fear from COVID-19. The top concern of patients was the wide community spread of COVID-19. Caregivers were primarily worried about patients dying alone. HCWs were most worried about the relatively mild symptoms of COVID-19. The prevalence of anxiety was 19.1%, 22.5%, and 14.0% for patients, caregivers, and HCWs, respectively. Patients who were nongraduates and married, and caregivers who were married were more anxious. The prevalence of burnout in HCWs was 43.5%, with more anxious and fearful HCWs reporting higher burnout rates.CONCLUSIONFears and anxiety related to COVID-19 are high. Burnout among HCWs is similar to rates reported prepandemic. An individualized approach to target the specific fears of each group will be crucial to maintain the well-being of these vulnerable groups and prevent burnout of HCWs.

Placental Pathology Findings during and after SARS-CoV-2 Infection: Features of Villitis and Malperfusion

Since the outbreak of coronavirus disease 2019 (COVID-19), there has been a debate whether pregnant women are at a specific risk for COVID-19 and whether it might be vertically transmittable through the placenta. We present a series of five placentas of SARS coronavirus 2 (SARS-CoV-2)-positive women who had been diagnosed with mild symptoms of COVID-19 or had been asymptomatic before birth. We provide a detailed histopathologic description of morphological changes accompanied by an analysis of presence of SARS-CoV-2 in the placental tissue. All placentas were term deliveries (40th and 41st gestational weeks). One SARS-CoV-2-positive patient presented with cough and dyspnoea. This placenta showed prominent lymphohistiocytic villitis and intervillositis and signs of maternal and foetal malperfusion. Viral RNA was present in both placenta tissue and the umbilical cord and could be visualized by in situ hybridization in the decidua. SARS-CoV-2 tests were negative at the time of delivery of 3/5 women, and their placentas did not show increased inflammatory infiltrates. Signs of maternal and/or foetal malperfusion were present in 100% and 40% of cases, respectively. There was no transplacental transmission to the infants. In our cohort, we can document different time points regarding SARS-CoV-2 infection. In acute COVID-19, prominent lymphohistiocytic villitis may occur and might potentially be attributable to SARS-CoV-2 infection of the placenta. Furthermore, there are histopathological signs of maternal and foetal malperfusion, which might have a relationship to an altered coagulative or microangiopathic state induced by SARS-CoV-2, yet this cannot be proven considering a plethora of confounding factors.

Clinical Presentation, Management and In-Hospital Outcome of Healthcare Personnel With COVID-19 Disease.

ObjectiveHealthcare personnel (HCP) are undoubtedly one of the major frontline fighters in the coronavirus disease 2019 (COVID-19) pandemic. Therefore, it comes as no surprise that many HCP have become infected by COVID-19 globally. The infection of HCP has received great attention in social media and is frequently reported from different parts of the world. However, there are few scientific reports addressing this aspect of the COVID-19 pandemic. The aim of this study was to evaluate the characteristics of clinical presentation, treatment, and outcome of COVID-19 infection among the HCP of our setting.MethodsThis cross-sectional study was performed in the National Heart Foundation Hospital & Research Institute of Bangladesh from April 29 to July 20, 2020. HCP employed in this hospital who experienced fever or respiratory symptoms or came in close contact with COVID-19 patients at home or their workplace were included in this study. The presence of COVID-19 disease was confirmed by real-time reverse transcriptase-polymerase chain reaction on nasopharyngeal samples. A total of 394 HCP were sampled and 139 had a positive corona test. Structured interviews were conducted to document symptoms for all HCP with confirmed COVID-19. Data analysis was performed in July 2020.ResultsOut of 1,409 HCP, 139 subjects tested positive for COVID-19. Among the HCP, infection rate was 9.86%. The mean age of the study population was 34.08±11.11 years (range: 20-69 yrs), of whom 82 (59%) were female. Most of this cohort were nurses (56 [40.3%]) and physicians (25 [18%]), and the remaining 58 (41.7%) were other staff. The mean duration of onset of symptoms to test was 2.89±2.07 days. The most common symptoms were fever (84.2%), fatigue (56.1%), cough (54%), body ache (39.6%), headache, and anosmia (38.8%). Most subjects had mild disease (125 [93%]), three (2.1%) of the HCP had moderate disease and one (0.7%) had severe disease. Ten of the HCP (7.2%) were asymptomatic. Most of them were treated either by ivermectin plus azithromycin or ivermectin plus doxycycline. Only 20 (14.4%) of the HCP were hospitalized, while others were treated either in home isolation (59.7%) or in institutional isolation (25.9%). Recovery was almost uneventful except one healthcare worker who died.ConclusionMost HCP had mild symptoms and a few of them were asymptomatic also. HCP with mild COVID-19 symptoms may be treated in home or institutional isolation. As they are a vulnerable group for infection, providing adequate protection to HCP is absolutely mandatory to safeguard them from this pandemic.

The relationship between resilience, anxiety and depression among patients with mild symptoms of COVID-19 in China: A cross-sectional study.

Aims and objectivesTo explore the role of resilience in anxiety and depression and to clarify their relationships among patients with mild symptoms of coronavirus disease 2019 (COVID‐19) in Wuhan, China.BackgroundThe outbreak of COVID‐19 has negatively affected some individuals, but resilience plays a decisive role in the response of individuals under pressure and can help them deal with pressure more effectively.DesignThe cross‐sectional descriptive correlational survey was reported in line with the STROBE guidelines.Subject and settingIn total, 296 patients from FangCang Hospital in Wuhan, Hubei, China, with mild symptoms of COVID‐19 were recruited.MethodsParticipants were recruited through convenience sampling. The data collected included their demographic information, the Connor‐Davidson Resilience Scale and Hospital Anxiety and Depression Scale.ResultsA small number of patients in this study had above threshold anxiety (subthreshold anxiety and major anxiety) and depression (subthreshold depression and major depression). The mean total resilience score of the participants was slightly below the normal level of ordinary Chinese adults. Resilience was inversely associated with and was a protective factor for both anxiety and depression in our samples. Risk factors for anxiety include being female and having colleagues with COVID‐19, while a risk factor for depression was having family members with COVID‐19.ConclusionsThis study shows that after taking the general demographics into consideration, higher levels of resilience were associated with lower anxiety and depression among mild COVID‐19 patients in Wuhan, China.Relevance to clinical practiceHealth professionals, especially clinical nurses, need to be aware of the psychological status of COVID‐19 patients and promote resilience to improve their mental health.

Immuno-Inflammatory Characteristics in Low Severity COVID-19 Patients with Digestive Symptoms.

Aim The outbreak of Coronavirus Disease 2019 (COVID-19) has resulted in a global pandemic, with the main manifestations being of respiratory nature, including pneumonia. It is noteworthy that digestive symptoms are also observed in COVID-19 patients. In this article, we describe the immuno-inflammatory characteristics of low severity COVID-19 patients with digestive symptoms. Methods Patients with mild symptoms of COVID-19 were split into three groups based on the patients' symptoms. The first group displayed digestive symptoms only, the second group displayed respiratory symptoms only, and the last group displayed both digestive and respiratory symptoms. Patients were discharged based on negative results of rRT-PCR testing for SARS-CoV-2 from at least two sequential respiratory tract specimens collected ≥24 hours apart. Multiorgan function and immuno-inflammatory characteristics were analyzed for all of the three groups. Results Mild liver damage and activation of the immuno-inflammatory system were the most common abnormalities observed in patients with mild COVID-19 symptoms but no significant differences were found (P > 0.05). Patients with digestive symptoms were more likely to have slightly higher and later peak values of inflammatory cytokines during the subsequent course of disease (P < 0.05). In addition, a significant correlation between IL-2 and TNF level was found in the first group which included patients with digestive symptoms only (P < 0.05). Conclusions Patients with mild cases of COVID-19 only displaying digestive symptoms are a special subtype. Patients in this group were more likely to have slightly higher and delayed peak values of inflammatory cytokines during the subsequent course of the disease. Prevention and clinical management of this type should be taken into consideration.

Evaluating the Association of Clinical Characteristics With Neutralizing Antibody Levels in Patients Who Have Recovered From Mild COVID-19 in Shanghai, China

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) threatens global public health. The association between clinical characteristics of the virus and neutralizing antibodies (NAbs) against this virus have not been well studied. To examine the association between clinical characteristics and levels of NAbs in patients who recovered from COVID-19. In this cohort study, a total of 175 patients with mild symptoms of COVID-19 who were hospitalized from January 24 to February 26, 2020, were followed up until March 16, 2020, at Shanghai Public Health Clinical Center, Shanghai, China. SARS-CoV-2 infections were diagnosed and confirmed by reverse transcriptase-polymerase chain reaction testing of nasopharyngeal samples. The primary outcome was SARS-CoV-2-specific NAb titers. Secondary outcomes included spike-binding antibodies, cross-reactivity against SARS-associated CoV, kinetics of NAb development, and clinical information, including age, sex, disease duration, length of stay, lymphocyte counts, and blood C-reactive protein level. Of the 175 patients with COVID-19, 93 were female (53%); the median age was 50 (interquartile range [IQR], 37-63) years. The median length of hospital stay was 16 (IQR, 13-21) days, and the median disease duration was 22 (IQR, 18-26) days. Variable levels of SARS-CoV-2-specific NAbs were observed at the time of discharge (50% inhibitory dose [ID50], 1076 [IQR, 448-2048]). There were 10 patients whose NAb titers were less than the detectable level of the assay (ID50, <40), and 2 patients who showed very high titers of NAbs, with ID50 levels of 15 989 and 21 567. NAbs were detected in patients from day 4 to 6 and reached peak levels from day 10 to 15 after disease onset. NAbs were unable to cross-react with SARS-associated CoV and NAb titers correlated with the spike-binding antibodies targeting S1 (r = 0.451; 95% CI, 0.320-0.564; P < .001), receptor binding domain (r = 0.484; 95% CI, 0.358-0.592; P < .001), and S2 regions (r = 0.346; 95% CI, 0.204-0.473; P < .001). NAb titers at the time of discharge were significantly higher in the 82 men (1417 [IQR, 541-2253]) than those in the 93 women (905 [IQR, 371-1687]) (median difference, 512; 95% CI, 82-688; P = .01) and at the time of follow-up in 56 male patients (1049 [IQR, 552-2454]) vs 61 female patients (751 [IQR, 216-1301]) (median difference, 298; 95% CI, 86-732; P = .009). Plasma NAb titers were significantly higher in 56 older (1537 [IQR, 877-2427) and 63 middle-aged (1291 [IQR, 504-2126]) patients than in 56 younger patients (459 [IQR, 225-998]) (older vs younger: median difference, 1078; 95% CI, 548-1287; P < .001; middle-aged vs younger: median difference, 832; 95% CI, 284-1013; P < .001). The NAb titers were correlated with plasma C-reactive protein levels (r = 0.508; 95% CI, 0.386-0.614; P < .001) and negatively correlated with lymphocyte counts (r = -0.427; 95% CI, -0.544 to -0.293; P < .001) at the time of admission. In this cohort study, among 175 patients who recovered from mild COVID-19 in Shanghai, China, NAb titers to SARS-CoV-2 appeared to vary substantially. Further research is needed to understand the clinical implications of differing NAb titers for protection against future infection.

Patients with Mild COVID-19 Symptoms and Coincident Pulmonary Embolism: A Case Series.

IntroductionFrequent thrombotic complications have been reported in patients with severe coronavirus disease 2019 (COVID-19) infection. The risk in patients with mild disease is unknown.Case ReportWe report a case series of three individuals recently diagnosed with COVID-19, who presented to the emergency department with chest pain and were found to have pulmonary emboli. The patients had mild symptoms, no vital sign abnormalities, and were negative according to the pulmonary embolism rule-out criteria.ConclusionThis suggests that patients with active or suspected COVID-19 should be considered at elevated risk for pulmonary embolism when presenting with chest pain, even without common risk factors for pulmonary embolism.

Virus shedding dynamics in asymptomatic and mildly symptomatic patients infected with SARS-CoV-2

ObjectivesAsymptomatic patients, together with those with mild symptoms of coronavirus disease 2019 (COVID-19), may play an important role in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. However, the dynamics of virus shedding during the various phases of the clinical course of COVID-19 remains unclear at this stage. MethodsA total of 18 patients found to be positive for SARS-CoV-2 infection by real-time reverse transcription PCR (RT-PCR) assay and admitted to Chongqing University Central Hospital between 29 January and 5 February 2020 were enrolled into this study. Medical data, pulmonary computed tomographic (CT) scan images and RT-PCR results were periodically collected during the patients' hospital stay. All participants were actively followed up for 2 weeks after discharge. ResultsA total of nine (50%) asymptomatic patients and nine (50%) patients with mild symptoms of COVID-19 were identified at admission. Six patients (66.7%) who were asymptomatic at admission developed subjective symptoms during hospitalization and were recategorized as being presymptomatic. The median duration of virus shedding was 11.5, 28 and 31 days for presymptomatic, asymptomatic and mildly symptomatic patients, separately. Seven patients (38.9%) continued to shed virus after hospital discharge. During the convalescent phase, detectable antibodies to SARS-CoV-2 and RNA were simultaneously observed in five patients (27.8%). ConclusionsLong-term virus shedding was documented in patients with mild symptoms and in asymptomatic patients. Specific antibody production to SARS-CoV-2 may not guarantee virus clearance after discharge. These observations should be considered when making decisions regarding clinical and public health, and when considering strategies for the prevention and control of SARS-CoV-2 infection.

Treatment of Acute Ischemic Stroke due to Large Vessel Occlusion With COVID-19: Experience From Paris.

Background and Purpose:Higher rates of strokes have been observed in patients with coronavirus disease 2019 (COVID-19), but data regarding the outcomes of COVID-19 patients suffering from acute ischemic stroke due to large vessel occlusion (LVO) are lacking. We report our initial experience in the treatment of acute ischemic stroke with LVO in patients with COVID-19.Methods:All consecutive patients with COVID-19 with acute ischemic stroke due to LVO treated in our institution during the 6 first weeks of the COVID-19 outbreak were included. Baseline clinical and radiological findings, treatment, and short-term outcomes are reported.Results:We identified 10 patients with confirmed COVID-19 treated for an acute ischemic stroke due to LVO. Eight were men, with a median age of 59.5 years. Seven had none or mild symptoms of COVID-19 at stroke onset. Median time from COVID-19 symptoms to stroke onset was 6 days. All patients had brain imaging within 3 hours from symptoms onset. Five patients had multi-territory LVO. Five received intravenous alteplase. All patients had mechanical thrombectomy. Nine patients achieved successful recanalization (mTICI2B-3), none experienced early neurological improvement, 4 had early cerebral reocclusion, and a total of 6 patients (60%) died in the hospital.Conclusions:Best medical care including early intravenous thrombolysis, and successful and prompt recanalization achieved with mechanical thrombectomy, resulted in poor outcomes in patients with COVID-19. Although our results require further confirmation, a different pharmacological approach (antiplatelet or other) should be investigated to take in account inflammatory and coagulation disorders associated with COVID-19.

Clinical Characteristics and Outcomes of 421 Patients With Coronavirus Disease 2019 Treated in a Mobile Cabin Hospital

BackgroundIn December 2019, a novel coronavirus-associated pneumonia, now known as coronavirus disease 2019 (COVID-19), was first detected in Wuhan, China. To prevent the rapid spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and treat patients with mild symptoms, sports stadiums and convention centers were reconstructed into mobile hospitals.Research QuestionIt is unknown whether a mobile cabin hospital can provide a safe treatment site for patients with mild COVID-19 symptoms.Study Design and MethodsThis study retrospectively reviewed the medical records of 421 patients with COVID-19 admitted to a mobile cabin hospital in Wuhan from February 9, 2020, to March 5, 2020. Clinical data comprised patient age, sex, clinical presentation, chest imaging, nucleic acid testing, length of hospitalization, and outcomes.ResultsOf the patients who were discharged from the cabin hospital, 362 (86.0%) were categorized as recovered; 14.0% developed severe symptoms and were transferred to a designated hospital. The most common presenting symptoms were fever (60.6%) and cough (52.0%); 5.2% exhibited no obvious symptoms. High fever (> 39.0°C) was more common in severe cases than in recovered cases (18.6% vs 6.6%). The distribution of lung lesions was peripheral in 85.0% of patients, multifocal in 69.4%, and bilateral in 68.2%. The most common pattern was ground-glass opacity (67.7%), followed by patchy shadowing (49.2%). The incidence of patchy shadowing was higher in patients with severe disease (66.1%) than in those who recovered (31.8%, P < .0001). The median length of hospitalization was 17 days (interquartile range, 14-19 days), and the median time taken for positive real-time reverse transcriptase polymerase chain reaction results to become negative in recovered patients was 8 days (interquartile range, 6-10 days).InterpretationMobile cabin hospitals provide a safe treatment site for patients with mild COVID-19 symptoms and offer an effective isolation area to prevent the spread of severe acute respiratory syndrome coronavirus 2.
