The epidemic, which started on 12 December , had caused 2, laboratory-confirmed infections including 80 deaths by 26 January Full-length genome sequences were obtained from five patients at an early stage of the outbreak. The sequences are almost identical and share Pairwise protein sequence analysis of seven conserved non-structural proteins domains show that this virus belongs to the species of SARSr-CoV. In addition, nCoV virus isolated from the bronchoalveolar lavage fluid of a critically ill patient could be neutralized by sera from several patients.

It has generally been thought that SARSr-CoV—which is mainly found in bats—could cause a future disease outbreak 10 , Here we report on a series of cases caused by an unidentified pneumonia disease outbreak in Wuhan, Hubei province, central China. This disease outbreak—which started from a local seafood market—has grown substantially to infect 2, people in China, is associated with 80 deaths and has led to the infection of 33 people in 10 additional countries as of 26 January Typical clinical symptoms of these patients are fever, dry cough, breathing difficulties dyspnoea , headache and pneumonia.

Disease onset may result in progressive respiratory failure owing to alveolar damage as observed by transverse chest computerized-tomography images and even death. The disease was determined to be caused by virus-induced pneumonia by clinicians according to clinical symptoms and other criteria, including a rise in body temperature, decreases in the number of lymphocytes and white blood cells although levels of the latter were sometimes normal , new pulmonary infiltrates on chest radiography and no obvious improvement after treatment with antibiotics for three days.

It appears that most of the early cases had contact history with the original seafood market; however, the disease has now progressed to be transmitted by human-to-human contact. Samples from seven patients with severe pneumonia six of whom are sellers or deliverymen from the seafood market , who were admitted to the intensive care unit of Wuhan Jin Yin-Tan Hospital at the beginning of the outbreak, were sent to the laboratory at the Wuhan Institute of Virology WIV for the diagnosis of the causative pathogen Extended Data Table 1.

One sample WIV04 , collected from the bronchoalveolar lavage fluid BALF , was analysed by metagenomics analysis using next-generation sequencing to identify potential aetiological agents. Of the 10,, total reads—of which 1, total reads were retained after filtering of reads from the human genome—1, High genome coverage was obtained by remapping the total reads to this genome Extended Data Fig.

M, membrane. The scale bars represent 0. Descriptions of the settings and software that was used are included in the Methods. The virus genome consists of six major open-reading frames ORFs that are common to coronaviruses and a number of other accessory genes Fig. However, the amino acid sequences of the seven conserved replicase domains in ORF1ab that were used for CoV species classification were The major differences in the sequence of the S gene of nCoV are the three short insertions in the N-terminal domain as well as changes in four out of five of the key residues in the receptor-binding motif compared with the sequence of SARS-CoV Extended Data Fig.

The close phylogenetic relationship to RaTG13 provides evidence that nCoV may have originated in bats. We rapidly developed a qPCR-based detection method on the basis of the sequence of the receptor-binding domain of the S gene, which was the most variable region of the genome Fig. However, we could no longer detect virus-positive samples in oral swabs, anal swabs and blood samples taken from these patients during the second sampling Fig.

On the basis of these findings, we propose that the disease could be transmitted by airborne transmission, although we cannot rule out other possible routes of transmission, as further investigation, including more patients, is required. Patient information can be found in Extended Data Tables 1 , 2. Detection methods are described in the Methods. AS, anal swab; OS, oral swab.

OD ratio, optical density at — nm. The asterisk indicates data collected from patient ICU on 10 January We were only able to obtain five serum samples from the seven patients with viral infections. We monitored viral antibody levels in one patient ICU 7, 8, 9 and 18 days after the onset of disease Extended Data Table 2. A clear trend was observed in the IgG and IgM titres, which increased over time, except that the IgM titre was decreased in the last sample Fig.

As a second analysis, we tested samples from 5 of the 7 virus-positive patients around 20 days after disease onset for the presence of viral antibodies Extended Data Tables 1 , 2. All patient samples—but not samples from healthy individuals—were strongly positive for viral IgG Fig. There were also three IgM-positive samples, indicating an acute infection.

Clear cytopathogenic effects were observed in cells after incubation for three days Extended Data Fig. Viral particles in ultrathin sections of infected cells displayed a typical coronavirus morphology, as visualized by electron microscopy Extended Data Fig. To further confirm the neutralization activity of the viral IgG-positive samples, we conducted serum-neutralization assays in Vero E6 cells using the five patient sera that were IgG-positive.

To determine whether nCoV also uses ACE2 as a cellular entry receptor, we conducted virus infectivity studies using HeLa cells that expressed or did not express ACE2 proteins from humans, Chinese horseshoe bats, civets, pigs and mice. Determination of virus infectivity in HeLa cells that expressed or did not express untransfected ACE2.

The study provides a detailed report on nCoV, the likely aetiological agent responsible for the ongoing epidemic of acute respiratory syndrome in China and other countries. Virus-specific nucleotide-positive and viral-protein seroconversion was observed in all patients tested and provides evidence of an association between the disease and the presence of this virus. However, there are still many urgent questions that remain to be answered.

We do not yet know the transmission routine of this virus among hosts. It appears that the virus is becoming more transmissible between humans. We should closely monitor whether the virus continues to evolve to become more virulent. Finally, considering the wide spread of SARSr-CoV in their natural reservoirs, future research should be focused on active surveillance of these viruses for broader geographical regions. In the long term, broad-spectrum antiviral drugs and vaccines should be prepared for emerging infectious diseases that are caused by this cluster of viruses in the future.

Most importantly, strict regulations against the domestication and consumption of wildlife should be implemented. No statistical methods were used to predetermine sample size. The experiments were not randomized and the investigators were not blinded to allocation during experiments and outcome assessment. Human samples, including oral swabs, anal swabs, blood and BALF samples were collected by Jinyintan hospital Wuhan, China with the consent of all patients and approved by the ethics committee of the designated hospital for emerging infectious diseases.

Patients were sampled without gender or age preference unless indicated. For swabs, 1. The supernatant was collected after centrifugation at 2, rpm, vortexing for 60 s and a standing period of 15—30 min. The supernatant from swabs or BALF no pre-treatment was added to either lysis buffer for RNA extraction or to viral transport medium for isolation of the virus. All cell lines were tested and free of mycoplasma contamination, submitted for species identification and authenticated by morphological evaluation by microscopy.

Cultured cell monolayers were maintained in their respective medium. The culture supernatant was examined for the presence of virus by qRT—PCR methods developed in this study, and cells were examined by immunofluorescence microscopy using the anti-SARSr-CoV Rp3 N antibody that was generated in-house , Vero E6 cells were infected with the new virus at a multiplicity of infection MOI of 0.

Cells were fixed with 2. Ultrathin sections 80 nm of embedded cells were prepared, deposited onto Formvar-coated copper grids mesh , stained with uranyl acetate and lead citrate, and analysed using a kV Tecnai G2 electron microscope. The virus neutralization test was carried out in a well plate. Each serum was assessed in triplicate. After removing the supernatant, the plate was washed twice with DMEM medium. Subsequently, the cells were checked for cytopathogenic effects.

The OD value — nm was calculated. HeLa cells transiently expressing ACE2 were prepared using Lipofectamine Thermo Fisher Scientific in a well plate; mock-transfected cells were used as controls. The inoculum was removed after absorption for 1 h and washed twice with PBS and supplemented with medium.

Viral replication was detected using a rabbit antibody against the Rp3 N protein generated in-house, , and a Cy3-conjugated goat anti-rabbit IgG , Abcam, ab Staining patterns were examined using confocal microscopy on a FV microscope Olympus.

The raw NGS reads were first processed by Cutadapt v. BWA v. Parameters for post-processing of assigned reads were set to a minimum size normalized abundance of 0. A local nucleic acid database for human and mammals was used to filter reads of host genomes before mapping reads to the virus database. The results of the metagenomic analysis were displayed as pie charts using Microsoft Office NGS reads were assembled into genomes using Geneious v.

PCR and Sanger sequencing was performed to fill gaps in the genome. Routine sequence management and analysis was carried out using DNAStar. Maximum likelihood phylogenetic trees were generated using RAxML v. Further information on research design is available in the Nature Research Reporting Summary linked to this paper. Li, W.
