Abstract
Introduction: Coronavirus disease 2019 (COVID-19) is a novel coronavirus that was extracted from patients with respiratory tract
infections. The most common symptoms of patients are fever and respiratory tract involvement. In this report, we describe one
patient with frequent seizures probably due to COVID-19 infection for the first time.
Case Presentation: A 30-year-old previously healthy female was admitted with generalized tonic-clonic seizure in the neurology
emergency room. The patient complained of dr y cough five days before the admission. She had seizures (five times) approximately
every 8 hours. Brain MRI was normal and chest CT revealed focal ground-glass opacities. The respiratory specimen was positive for
COVID-19 using real-time PCR assay. The symptoms of the patient improved with anticonvulsive and antiviral medications.
Conclusions: Tothe best of our knowledge, this is the first case study to report an association between frequent seizures and COVID-
19. In our opinion, there is a hypothesis about this subject that the etiology of seizure may be due to encephalitis and invasion virus
to the brain or toxic effect of inflammatory cytokines.

1. Introduction
Coronavirus disease 2019 (COVID-19) is a novel coron-
avirus that was extracted from patients with respiratory
tract infection of unknown causes on December 31, 2019,
in Wuhan, Hubei, China (1-3). The infected patients’ symp-
toms ranged from asymptomatic to severe (4). The most
common complaints of patients are fever (98%), cough
(76%), dyspnea (55%), myalgia, and fatigue (44%) (5-7). Some
pieces of evidence reported gastrointestinal involvement,
acute cardiac injury, and acute kidney injury due to COVID-
19 (7,8). Mao et al. (9) reported neurological manifesta-
tions of patients with COVID-19. The most common symp-
toms were dizziness, headache, hypogeusia, and hypos-
mia (9). Severe patients had ischemic or hemorrhagic
stroke, and loss of consciousness (9). At this time, the like-
lihood of COVID-19 should be considered primarily in pa-
tients with fever and/or respiratory tract symptoms who
had close contact with a confirmed or suspected patient
of COVID-19 (1). Real-time polymerase chain reaction (real-
time PCR) and next-generation sequencing were used for
definitive diagnosis of this novel coronavirus (5). To the
best of our knowledge, up to now, no seizure was reported
due to COVID-19. In this report, we describe one patient
with frequent seizures probably owing to COVID19 for the
first time.
2. Case Presentation
A 30-year-old previously healthy female was admit-
ted with generalized tonic-clonic seizure in the neurol-
ogy emergency room in Bou Ali Sina Hospital, Mazandaran
Province, Iran. The patient had no history of drug and alco-
hol abuse. She complained of dry cough five days before
admission. Three days prior to admission, she had fever
(T = 38°C axillary) and fatigue. The first generalized tonic-
clonic seizure (GTC) of the patient occurred in the sleep,
two days before the admission. Then, recurrent seizures
(five times) happened approximately every 8 hours. Also,
one seizure attack arose in the hospital, at the admission
time. As the seizure ended, the patient was sleepy and con-
fused for thirty minutes to one hour. The patient was con-
scious between attacks. She neither had a history of epilep-
tic seizures nor a family history concerning seizure disor-
ders. At the time of hospitalization in the Emergency De-
partment, the body temperature was 38.8°C, blood pres-
sure 130/70 mmHg, heart rate 98 beats/minute, respiratory

rate 20/minute and oxygen saturation of 96% on room air.
The bedside serum glucose level was 108 mg/dL. In terms
of neurological examination, the patient was drowsy with
disorientation to time. The cranial nerves were intact.
Pupils were midsize and reactive to light and accommo-
dation. There was no optic disc swelling bilaterally. The
patient was able to move all four extremities and there
was no stiff neck and nuchal rigidity. Deep tendon reflexes
were normal. Considering general examination, no skin
rash was observed and other systems, including cardiac
and abdominal examination, were normal. Primary labo-
ratory tests discovered a normal blood sugar, electrolytes,
calcium, phosphor, magnesium, liver function test, urea,
and creatinine. The blood sample revealed the following
results: white blood cell count 5,500 cells per microliter
with 26% lymphocytes and 70% neutrophils, mildly ele-
vated erythrocyte sedimentation rate (ESR = 35 mm/hour),
and normal C-reactive protein (CRP). Lumbar puncture was
done and the cerebrospinal fluid (CSF) showed normal pro-
tein, glucose, with five cell counts (all of them were lym-
phocytes). There was no bacterial growth after 48 hours of
incubation. Brain MRI was normal. Given that the patient
had cough and fever, the chest computed tomography (CT)
was done and revealed focal ground-glass opacities (Fig-
ure 1). Respiratory specimens, including nasal and phar yn-
geal swabs, and CSF sample were tested for COVID-19 using
real-time PCR in the Health Center no. 5 (Shahid Ghasemi)
Laboratory. This center is under the supervision of Mazan-
daran University of Medical Sciences. Nasal and pharyn-
geal samples were positive for COVID-19. The CSF sample
was unremarkable for COVID-19 infection. The patient was
treated with intravenous phenytoin and levetiracetam. In
addition, the patient received chloroquine 200 mg BD and
Lopinavir-ritonavir 400/100 mg bd. The patient was mon-
itored for one week. Fever and seizure of the patient were
controlled.
3. Discussion
Coronavirus disease 2019 (COVID-19) is beta coron-
aviruses, similar to severe acute respiratory syndrome
coronavirus (SARS-CoV) in 2003 but with a different mono-
phyletic group. Both viruses bind to receptor angiotensin-
converting enzyme 2 (ACE2) to enter the cell (10,11). The
most well-known clinical symptoms of this virus are respi-
ratory symptoms. Moreover, Mao et al. (9) described neu-
rological presentations of infected patients with COVID-19.
The most common reported symptoms were headache and
dizziness. In this report, we reported a case with COVID-19
and frequent seizures, with no past medical history. There
are many different viruses that play a role in the develop-
ment of seizures and convulsions (12). The causes of seizure
Figure 1. Chest computer tomography in the patient with COVID-19 is shown
may be due to a primary infection or due to reactivation of
the latent virus. There are several mechanisms for the eti-
ology of seizure in the patients who suffer from viral infec-
tions, including direct infiltration of brain tissue and pro-
duction of toxins by the virus or production of inflamma-
tory mediators by the brain (13). Huang et al. (2) reported
that COVID-19 provokes the inflammatory cascade and as
a result, releases inflammatory cytokines, including inter-
leukins 2, 6, 7, and 10, tumor necrotizing αand the granu-
locyte colony-stimulating factor. Previous studies reported
that TNF-αand IL-6 cytokines and C3 of the complement
system are the main factors of stimulating the immune sys-
tem. Consecutively, these cytokines can drive neuronal hy-
perexcitability via activation of glutamate receptors and
play a role in the development of acute seizures(14-16).
3.1. Conclusions
To the best of our knowledge, this is the first case study
that reports an association between frequent seizures and
COVID-19. In our opinion, there is a hypothesis about this
subject that the etiology of seizure may be encephalitis
and the invasion of the virus to the brain or toxic effect of
inflammatory cytokines.

... In total, only a limited number of cases with new-onset or acute seizures have been reported so far [2,[9][10][11][12][13][14][15][16][17]. Despite the relatively low risk, the possibility of their occurrence in the course of the disease should not be ruled out. ...
... Multiple studies reported a variety of characteristics: 1. Clinical manifestations of new-onset seizures -focal or generalized onset, clusters of seizures, and status epilepticus in the course of COVID-19 infection; 2. Age of patients -children or older people; 3. EEG findings -normal, focal epileptiform discharges, or consistent with status epilepticus; 4. CSF -results -normal or abnormal; 5. Antiseizure medications -type, monotherapy, or combination therapy; 6. Outcome -favorable, severe disability, or death, especially in case of severe COVID-19 infection. Most of them were single case studies, case series, or retrospective studies [2,9,10,[12][13][14][15][16][17]19]. Many patients in these studies had comorbidities or specific neurological problems and received medications [2,15,20]. ...

Introduction: The aim of our study is to assess the clinical manifestations, investigation results, and outcomes in Bulgarian patients with seizures in the course of COVID-19 infection. Methods: We performed an open, prospective study during a 12-month period from January 2021 with the participation of 290 inpatients and outpatients with seizures who attended the Clinic of Neurology at the University Hospital in Plovdiv, Bulgaria. After a detailed anamnesis, they underwent neurological examination, EEG, neuroimaging, and lumbar puncture when needed. There was a prospective one-year follow-up regarding seizure frequency, EEG, and treatment. Results: In 18 (5.9%) patients, seizures were related to COVID-19 infection. Nine (3.1%) patients had new-onset seizures, and in nine (3.1%) participants with epilepsy, there was a worsening of seizure frequency. New-onset seizures were more likely to occur in people above 65 years of age, within one to two months from the infection diagnosis. In one participant, seizures were related to fever. The most common seizure types were generalized tonic-clonic and focal motor seizures with/without loss of awareness. Antiseizure medications were started in seven participants. Viral encephalopathy was confirmed in two patients, one of them died. EEG showed focal epileptiform activity in four participants. The one-year prospective observation showed a favorable outcome in five patients who were without seizures, had normal EEG, and three were without treatment. Seizure frequency increase or seizure recurrence was typically observed for a short period of time in the epilepsy group. EEG was worsened in one patient and treatment changes were needed in five participants. Conclusion: In conclusion, our study results provide evidence about the progress and possible relationship between new-onset seizures and seizure worsening with COVID-19 infection.

The SARS-CoV-2 virus has spread rapidly despite implementing strategies to reduce its transmission. The disease caused by this virus has been associated with a diverse range of symptoms, including common neurological manifestations such as dysgeusia, anosmia, and myalgias. Additionally, numerous cases of severe neurological complications associated with this disease have been reported, including encephalitis, stroke, seizures, and Guillain–Barré syndrome, among others. Given the high prevalence of neurological manifestations in this disease, the objective of this review is to analyze the mechanisms by which this virus can affect the nervous system, from its direct invasion to aberrant activation of the immune system and other mechanisms involved in the symptoms, including neuropsychiatric manifestations, to gain a better understanding of the disease and thus facilitate the search for effective therapeutic strategies.

As is known, the issues of pathogenesis, diagnosis and treatment of the new coronavirus infection COVID-19 are the most priority areas of scientific research in the modern clinic of internal diseases. The rate of emergence of new scientific data in the leading libraries PubMed, Medline, Cochrane Library and eLibrary, which can potentially be important in the correction of ongoing therapy for infection and its complications, is extremely high. In turn, this dictates the need for a comprehensive discussion of the results of newly published studies. These issues include clinical and neurological manifestations of COVID-19 and other coronavirus infections. The exact mechanism by which the SARS-CoV-2 virus enters the structures of the central nervous system is unknown. Thus, two pathways for the penetration of the COVID-19 pathogen are most actively discussed: the hematogenous pathway (through the systemic circulation into the vessels of the brain with a low linear blood flow velocity, which allows the virus to adhere to the surface of the endothelium and penetrate into the nervous tissue through damage to the latter) and the contact pathway (through the cribriform plate and the olfactory bulb). It should also be noted that a number of experimental works clearly demonstrate the pathogenic effect of other members of the Coronaviridae family on the neurons of the respiratory and vasomotor centers. The review presents an analysis of current literature data on the study of clinical and neurological manifestations of COVID-19 and other coronavirus infections. It is important to emphasize that patients with a severe course of COVID-19 deserve special attention, requiring observation in the intensive care unit in order to prevent the development of fatal neurological complications.
... The study emphasized how crucial it is to recognize neurologic signs as a critical presentation of COVID-19 indication. Seven individuals had their CSF specimens sampled for infection with SARS-CoV-2, and among the 20 studies that were available,[20][21][22] only one resulted in a positive result when meningitis/encephalitis signs were present.21 ...

Patients with COVID-19 and other coronavirus infections have been documented as having a variety of neurologic symptoms. In this article, we conducted a thorough evaluation of the imaging results of individuals who had been identified as having neurological symptoms linked to coronavirus infections. The use of CT and MRI has revealed varying radiologic outcomes in the setting of various neurologic presentations. Despite the fact that the majority of patients have normal imaging analyses, certain patients exhibit intra-and extra-axial abnormalities. There have been reports of encephalomyelitis, meningitis, acute disseminated encephalomyelitis (ADEM), ischemic and hemorrhagic strokes, and encephalopathy. Especially during the present COVID-19 pandemic, familiarity with these radiologic patterns can help radiologists and referring doctors investigate coronavirus infections in patients with worsening or progressing neurologic symptoms.

In recent years, there has been a lot of interest in using nanotechnology in medicine to diagnose and cure various infectious diseases. Although the precise mechanism of action is frequently challenged, many nanosized materials have been extensively explored for this purpose, using their innately unique features. Their functionality has also been enhanced by the addition of various coatings, such as those that increase chemical stability and stealth properties or contain targeting agents that lessen off-target effects while producing effective "smart" nanoplatforms for the early detection, treatment, and possibly resolution of diseases. This book aims to compile research and review articles that concentrate on the synthesis, characterization, and applications of nanomaterials, such as nanoparticles, with a focus on investigating novel ways to improve their properties and create new efficient diagnostic, therapeutic, or theranostic approaches with a clear understanding of how they work.

Importance In December 2019, novel coronavirus (2019-nCoV)–infected pneumonia (NCIP) occurred in Wuhan, China. The number of cases has increased rapidly but information on the clinical characteristics of affected patients is limited. Objective To describe the epidemiological and clinical characteristics of NCIP. Design, Setting, and Participants Retrospective, single-center case series of the 138 consecutive hospitalized patients with confirmed NCIP at Zhongnan Hospital of Wuhan University in Wuhan, China, from January 1 to January 28, 2020; final date of follow-up was February 3, 2020. Exposures Documented NCIP. Main Outcomes and Measures Epidemiological, demographic, clinical, laboratory, radiological, and treatment data were collected and analyzed. Outcomes of critically ill patients and noncritically ill patients were compared. Presumed hospital-related transmission was suspected if a cluster of health professionals or hospitalized patients in the same wards became infected and a possible source of infection could be tracked. Results Of 138 hospitalized patients with NCIP, the median age was 56 years (interquartile range, 42-68; range, 22-92 years) and 75 (54.3%) were men. Hospital-associated transmission was suspected as the presumed mechanism of infection for affected health professionals (40 [29%]) and hospitalized patients (17 [12.3%]). Common symptoms included fever (136 [98.6%]), fatigue (96 [69.6%]), and dry cough (82 [59.4%]). Lymphopenia (lymphocyte count, 0.8 × 10⁹/L [interquartile range {IQR}, 0.6-1.1]) occurred in 97 patients (70.3%), prolonged prothrombin time (13.0 seconds [IQR, 12.3-13.7]) in 80 patients (58%), and elevated lactate dehydrogenase (261 U/L [IQR, 182-403]) in 55 patients (39.9%). Chest computed tomographic scans showed bilateral patchy shadows or ground glass opacity in the lungs of all patients. Most patients received antiviral therapy (oseltamivir, 124 [89.9%]), and many received antibacterial therapy (moxifloxacin, 89 [64.4%]; ceftriaxone, 34 [24.6%]; azithromycin, 25 [18.1%]) and glucocorticoid therapy (62 [44.9%]). Thirty-six patients (26.1%) were transferred to the intensive care unit (ICU) because of complications, including acute respiratory distress syndrome (22 [61.1%]), arrhythmia (16 [44.4%]), and shock (11 [30.6%]). The median time from first symptom to dyspnea was 5.0 days, to hospital admission was 7.0 days, and to ARDS was 8.0 days. Patients treated in the ICU (n = 36), compared with patients not treated in the ICU (n = 102), were older (median age, 66 years vs 51 years), were more likely to have underlying comorbidities (26 [72.2%] vs 38 [37.3%]), and were more likely to have dyspnea (23 [63.9%] vs 20 [19.6%]), and anorexia (24 [66.7%] vs 31 [30.4%]). Of the 36 cases in the ICU, 4 (11.1%) received high-flow oxygen therapy, 15 (41.7%) received noninvasive ventilation, and 17 (47.2%) received invasive ventilation (4 were switched to extracorporeal membrane oxygenation). As of February 3, 47 patients (34.1%) were discharged and 6 died (overall mortality, 4.3%), but the remaining patients are still hospitalized. Among those discharged alive (n = 47), the median hospital stay was 10 days (IQR, 7.0-14.0). Conclusions and Relevance In this single-center case series of 138 hospitalized patients with confirmed NCIP in Wuhan, China, presumed hospital-related transmission of 2019-nCoV was suspected in 41% of patients, 26% of patients received ICU care, and mortality was 4.3%.

Since the SARS outbreak 18 years ago, a large number of severe acute respiratory syndrome-related coronaviruses (SARSr-CoV) have been discovered in their natural reservoir host, bats1–4. Previous studies indicated that some of those bat SARSr-CoVs have the potential to infect humans5–7. Here we report the identification and characterization of a novel coronavirus (2019-nCoV) which caused an epidemic of acute respiratory syndrome in humans in Wuhan, China. The epidemic, which started from 12 December 2019, has caused 2,050 laboratory-confirmed infections with 56 fatal cases by 26 January 2020. Full-length genome sequences were obtained from five patients at the early stage of the outbreak. They are almost identical to each other and share 79.5% sequence identify to SARS-CoV. Furthermore, it was found that 2019-nCoV is 96% identical at the whole-genome level to a bat coronavirus. The pairwise protein sequence analysis of seven conserved non-structural proteins show that this virus belongs to the species of SARSr-CoV. The 2019-nCoV virus was then isolated from the bronchoalveolar lavage fluid of a critically ill patient, which can be neutralized by sera from several patients. Importantly, we have confirmed that this novel CoV uses the same cell entry receptor, ACE2, as SARS-CoV.

A novel coronavirus (2019-nCov) was identified in Wuhan, Hubei Province, China in December of 2019. This new coronavirus has resulted in thousands of cases of lethal disease in China, with additional patients being identified in a rapidly growing number internationally. 2019-nCov was reported to share the same receptor, Angiotensin-converting enzyme 2 (ACE2), with SARS-Cov. Here based on the public database and the state-of-the-art single-cell RNA-Seq technique, we analyzed the ACE2 RNA expression profile in the normal human lungs. The result indicates that the ACE2 virus receptor expression is concentrated in a small population of type II alveolar cells (AT2). Surprisingly, we found that this population of ACE2-expressing AT2 also highly expressed many other genes that positively regulating viral reproduction and transmission. A comparison between eight individual samples demonstrated that the Asian male one has an extremely large number of ACE2-expressing cells in the lung. This study provides a biological background for the epidemic investigation of the 2019-nCov infection disease, and could be informative for future anti-ACE2 therapeutic strategy development.

Background: A recent cluster of pneumonia cases in Wuhan, China, was caused by a novel betacoronavirus, the 2019 novel coronavirus (2019-nCoV). We report the epidemiological, clinical, laboratory, and radiological characteristics and treatment and clinical outcomes of these patients. Methods: All patients with suspected 2019-nCoV were admitted to a designated hospital in Wuhan. We prospectively collected and analysed data on patients with laboratory-confirmed 2019-nCoV infection by real-time RT-PCR and next-generation sequencing. Data were obtained with standardised data collection forms shared by the International Severe Acute Respiratory and Emerging Infection Consortium from electronic medical records. Researchers also directly communicated with patients or their families to ascertain epidemiological and symptom data. Outcomes were also compared between patients who had been admitted to the intensive care unit (ICU) and those who had not. Findings: By Jan 2, 2020, 41 admitted hospital patients had been identified as having laboratory-confirmed 2019-nCoV infection. Most of the infected patients were men (30 [73%] of 41); less than half had underlying diseases (13 [32%]), including diabetes (eight [20%]), hypertension (six [15%]), and cardiovascular disease (six [15%]). Median age was 49·0 years (IQR 41·0-58·0). 27 (66%) of 41 patients had been exposed to Huanan seafood market. One family cluster was found. Common symptoms at onset of illness were fever (40 [98%] of 41 patients), cough (31 [76%]), and myalgia or fatigue (18 [44%]); less common symptoms were sputum production (11 [28%] of 39), headache (three [8%] of 38), haemoptysis (two [5%] of 39), and diarrhoea (one [3%] of 38). Dyspnoea developed in 22 (55%) of 40 patients (median time from illness onset to dyspnoea 8·0 days [IQR 5·0-13·0]). 26 (63%) of 41 patients had lymphopenia. All 41 patients had pneumonia with abnormal findings on chest CT. Complications included acute respiratory distress syndrome (12 [29%]), RNAaemia (six [15%]), acute cardiac injury (five [12%]) and secondary infection (four [10%]). 13 (32%) patients were admitted to an ICU and six (15%) died. Compared with non-ICU patients, ICU patients had higher plasma levels of IL2, IL7, IL10, GSCF, IP10, MCP1, MIP1A, and TNFα. Interpretation: The 2019-nCoV infection caused clusters of severe respiratory illness similar to severe acute respiratory syndrome coronavirus and was associated with ICU admission and high mortality. Major gaps in our knowledge of the origin, epidemiology, duration of human transmission, and clinical spectrum of disease need fulfilment by future studies.

Objective: To analyze the clinical characteristics of 2019 novel coronavirus (2019-nCoV) pneumonia and to investigate the correlation between serum inflammatory cytokines and severity of the disease. Methods: 29 patients with 2019-ncov admitted to the isolation ward of Tongji hospital affiliated to Tongji medical college of Huazhong University of Science and Technology in January 2020 were selected as the study subjects. Clinical data were collected and the general information, clinical symptoms, blood test and CT imaging characteristics were analyzed. According to the relevant diagnostic criteria, the patients were divided into three groups: mild (15 cases), severe (9 cases) and critical (5 cases). The expression levels of inflammatory cytokines and other markers in the serum of each group were detected, and the changes of these indicators of the three groups were compared and analyzed, as well as their relationship with the clinical classification of the disease. Results: (1) The main symptoms of 2019-nCoV pneumonia was fever (28/29) with or without respiratory and other systemic symptoms. Two patients died with underlying disease and co-bacterial infection, respectively. (2) The blood test of the patients showed normal or decreased white blood cell count (23/29), decreased lymphocyte count (20/29), increased hypersensitive C reactive protein (hs-CRP) (27/29), and normal procalcitonin. In most patients,serum lactate dehydrogenase (LDH) was significantly increased (20/29), while albumin was decreased(15/29). Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), serum creatinine (Scr) and other items showed no significant changes. (3) CT findings of typical cases were single or multiple patchy ground glass shadows accompanied by septal thickening. When the disease progresses, the lesion increases and the scope expands, and the ground glass shadow coexists with the solid shadow or the stripe shadow. (4) There were statistically significant differences in the expression levels of interleukin-2 receptor (IL-2R) and IL-6 in the serum of the three groups (P<0.05), among which the critical group was higher than the severe group and the severe group was higher than the mildgroup. However, there were no statistically significant differences in serum levels of tumor necrosis factor-alpha (TNF-α), IL-1, IL-8, IL-10, hs-CRP, lymphocyte count and LDH among the three groups (P>0.05). Conclusion: The clinical characteristics of 2019-nCoV pneumonia are similar to those of common viral pneumonia. High resolution CT is of great value in the differential diagnosis of this disease. The increased expression of IL-2R and IL-6 in serum is expected to predict the severity of the 2019-nCoV pneumonia and the prognosis of patients.

Background The chest CT findings of patients with 2019 Novel Coronavirus (2019-nCoV) pneumonia have not previously been described in detail.PurposeTo investigate the clinical, laboratory, and imaging findings of emerging 2019-nCoV pneumonia in humans.Materials and Methods Fifty-one patients (25 men and 26 women; age range 16-76 years) with laboratory-confirmed 2019-nCoV infection by using real-time reverse transcription polymerase chain reaction underwent thin-section CT. The imaging findings, clinical data, and laboratory data were evaluated.ResultsFifty of 51 patients (98%) had a history of contact with individuals from the endemic center in Wuhan, China. Fever (49 of 51, 96%) and cough (24 of 51, 47%) were the most common symptoms. Most patients had a normal white blood cell count (37 of 51, 73%), neutrophil count (44 of 51, 86%), and either normal (17 of 51, 35%) or reduced (33 of 51, 65%) lymphocyte count. CT images showed pure ground-glass opacity (GGO) in 39 of 51 (77%) patients and GGO with reticular and/or interlobular septal thickening in 38 of 51 (75%) patients. GGO with consolidation was present in 30 of 51 (59%) patients, and pure consolidation was present in 28 of 51 (55%) patients. Forty-four of 51 (86%) patients had bilateral lung involvement, while 41 of 51 (80%) involved the posterior part of the lungs and 44 of 51 (86%) were peripheral. There were more consolidated lung lesions in patients 5 days or more from disease onset to CT scan versus 4 days or fewer (431 of 712 lesions vs 129 of 612 lesions; P < .001). Patients older than 50 years had more consolidated lung lesions than did those aged 50 years or younger (212 of 470 vs 198 of 854; P < .001). Follow-up CT in 13 patients showed improvement in seven (54%) patients and progression in four (31%) patients.Conclusion Patients with fever and/or cough and with conspicuous ground-glass opacity lesions in the peripheral and posterior lungs on CT images, combined with normal or decreased white blood cells and a history of epidemic exposure, are highly suspected of having 2019 Novel Coronavirus (2019-nCoV) pneumonia.© RSNA, 2020.

Background: In December, 2019, a pneumonia associated with the 2019 novel coronavirus (2019-nCoV) emerged in Wuhan, China. We aimed to further clarify the epidemiological and clinical characteristics of 2019-nCoV pneumonia. Methods: In this retrospective, single-centre study, we included all confirmed cases of 2019-nCoV in Wuhan Jinyintan Hospital from Jan 1 to Jan 20, 2020. Cases were confirmed by real-time RT-PCR and were analysed for epidemiological, demographic, clinical, and radiological features and laboratory data. Outcomes were followed up until Jan 25, 2020. Findings: Of the 99 patients with 2019-nCoV pneumonia, 49 (49%) had a history of exposure to the Huanan seafood market. The average age of the patients was 55·5 years (SD 13·1), including 67 men and 32 women. 2019-nCoV was detected in all patients by real-time RT-PCR. 50 (51%) patients had chronic diseases. Patients had clinical manifestations of fever (82 [83%] patients), cough (81 [82%] patients), shortness of breath (31 [31%] patients), muscle ache (11 [11%] patients), confusion (nine [9%] patients), headache (eight [8%] patients), sore throat (five [5%] patients), rhinorrhoea (four [4%] patients), chest pain (two [2%] patients), diarrhoea (two [2%] patients), and nausea and vomiting (one [1%] patient). According to imaging examination, 74 (75%) patients showed bilateral pneumonia, 14 (14%) patients showed multiple mottling and ground-glass opacity, and one (1%) patient had pneumothorax. 17 (17%) patients developed acute respiratory distress syndrome and, among them, 11 (11%) patients worsened in a short period of time and died of multiple organ failure. Interpretation: The 2019-nCoV infection was of clustering onset, is more likely to affect older males with comorbidities, and can result in severe and even fatal respiratory diseases such as acute respiratory distress syndrome. In general, characteristics of patients who died were in line with the MuLBSTA score, an early warning model for predicting mortality in viral pneumonia. Further investigation is needed to explore the applicability of the MuLBSTA score in predicting the risk of mortality in 2019-nCoV infection. Funding: National Key R&D Program of China.
