Background: Novel coronavirus outbreak that originated in Wuhan, province of China has now been declared as one of the deadliest pandemics inflicting humankind in last hundred years. Method: In the present study, we have inferred the clinical, laboratory, radiological, and microbiological findings of five patients in a family cluster who presented with unexplained pneumonia after coming back from overseas and touchdown right here in India on 1st March 2020 earlier than lockdown and another member of the family who didn’tvisit thiscountry. Results: From March 10, 2020, we enrolled a family of six patients who travelled to SingaporeonJanuary 10th 2020and returned on March 1st 2020. Of six family members who travelled to Singapore, five were recognised as affected with the radical coronavirus (COVID 19). Additionally, one family member, who did not travel to overseas also became infected with the virus post14 days of staying with four of the family members. Five family members (aged 30–55 years) presented with symptoms like fever, upper or lower respiratory tract symptoms, or diarrhoea, or a combination of these 3–6 days after exposure. Phylogenetic evaluation of these five subjects’ RT-PCR amplicons and two full genomes by nextgeneration sequencing presented that this is a novel coronavirus, which is closest to the severe acute respiratory syndrome (SARS)-related coronaviruses. Conclusion: Our findings are steady with person-to-person transmission of this novel coronavirus in hospital (nosocomial) and family settings, and the reports of infected travellers in other geographical regions.
Lower respiratory tract samples are reliable for severe acute respiratory syndrome coronavirus 2 nucleic acid diagnosis and animal model study
