Sep 11th, 2020 - In recent months it has emerged that the novel coronavirus-responsible for the COVID-19 pandemic-causes reduction of smell and taste in a large fraction of patients. The chemosensory deficits are often the earliest, and sometimes the only signs in otherwise asymptomatic carriers of the SARS-CoV-2 virus. The reasons for the surprisingly early and specific chemosensory dysfunction in COVID-19 are...

Infectious COVID-19 Can Persist in Gut for Weeks
https://www.medscape.com/viewarticle/937256

Sep 10th, 2020 - For the first time, researchers detected active and prolonged infection of SARS-CoV-2 virus in the gastrointestinal (GI) tracts of people with confirmed COVID-19. Stool tests were positive among people with no GI symptoms, and in some cases up to 6 days after nasopharyngeal swabs yielded negative results. The small pilot study suggests a quiescent but active infection in the gut. Stool testing ...

Infected Children May Go Unnoticed, Study Says

Aug 24th, 2020 - Several countries have undertaken social distancing measures to stop SARS-CoV-2 spread. Asymptomatic carriers' prevalence is unknown and would provide essential information on hidden viral circulation. In our cross-sectional study, 1.82% of 330 asymptomatic confined individuals living in the community carried SARS-CoV-2 despite no contact with declared cases, raising concerns about unnoticed tr...

Aug 17th, 2020 - The COVID-19 pandemic is caused by severe acute respiratory syndrome coronavirus 2 and causing a global public health emergency. During the outbreak, Wuhan was the first reported and hardest-hit city. With the dramatic drop in number of confirmed cases and subsequent ending of Wuhan lock down, asymptomatic carriers and patients in their recovery period still pose an increased risk. Strict and e...

Aug 10th, 2020 - The clinical onset serial interval is often used as a proxy for the transmission interval of an infectious disease. For SARS-CoV-2/COVID-19, data on clinical onset serial intervals is limited, since symptom onset dates are not routinely recorded and do not exist in asymptomatic carriers. We define the diagnostic serial interval as the time between the diagnosis dates of the infector and infecte...

Jul 10th, 2020 - An ongoing outbreak of coronavirus disease 2019 (COVID-19) has rapidly spread in the world, whereas asymptomatic carriers may also play a critical role in the pandemic. We report a familial cluster of COVID-19 caused by one family member before his onset of illness, indicating that it seems to be potentially infectious during the incubation period, even earlier than we expected. Close contact, ...
