Les bien-portants, dits “asymptomatiques”, ne transmettent pas le Covid19 : étude chinoise sur 10 millions de personnes !

Depuis le début de l’épidémie de Covid19, les modes précis de la transmission et le rôle des asymptomatiques dans celle-ci font débat. Cette dernière question vient d’être tranchée par l’analyse d’un étude chinoise géante de Wuhan qui démontre que les asymptomatiques ne contaminent personne.

Cold-chain food contamination as the possible origin of Covid-19 resurgence in Beijing

Covid-19, caused by SARS-CoV-2, has been contained in China through stringent non-pharmaceutical interventions. The border control and quarantine have effectively prevented the virus spread by infected travellers, but the risk of resurgence caused by other routes of introduction and transmission remains unclear, and current strategies to prevent resurgence could be flawed. Since July, SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China. However, there is no robust evidence of Covid-19 outbreaks initiated by environment-to-human transmission. Here we add to evidence of such transmission by investigating the recent Covid-19 resurgence in Beijing.


[Japon] COVID-19 patients with no symptoms likely to stay that way: Japanese researchers

What are the odds COVID-19 patients with no symptoms could develop them later on?

Quite slim, according to a recent study led by a group of researchers in Aichi Prefecture, who have discovered that asymptomatic coronavirus patients tend to recover within nine days of having their infections confirmed via polymerase chain reaction (PCR) tests.


SARS-CoV-2 shedding and seroconversion among passengers quarantined after disembarking a cruise ship: a case series

Background – A cruise ship is a closed-off environment that simulates the basic functioning of a city in terms of living conditions and interpersonal interactions. Thus, the Diamond Princess cruise ship, which was quarantined because of an onboard outbreak of COVID-19 in February, 2020, provides an opportunity to define the shedding pattern of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and patient antibody responses before and after the onset of symptoms.
