Household secondary attack rate of COVID-19 and associated determinants in Guangzhou, China: a retrospective cohort study

As of June 8, 2020, the global reported number of COVID-19 cases had reached more than 7 million with over 400 000 deaths. The household transmissibility of the causative pathogen, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), remains unclear. We aimed to estimate the secondary attack rate of SARS-CoV-2 among household and non-household close contacts in Guangzhou, China, using a statistical transmission model.

[Taiwan] Chang Gung trouve un anticorps monoclonal clé efficace à 90% contre le nouveau coronavirus

Début avril, l’équipe composée des chercheurs de l’Université et de l’hôpital Chang Gung, de l’Academia Sinica, du centre médical du ministère de la Défense et de l’Université Oxford avaient identifié 25 anticorps monoclonaux sur les patients atteints du Covid-19. Aujourd’hui, l’hôpital Chang Gung annonce avoir trouvé un anticorps monoclonal capable d’empêcher le virus du SARS-CoV-2 de pénétrer dans le corps humain avec une capacité de l’inhiber allant de 90% à 98%.

PKU-led team found effective SARS-CoV-2 neutralizing antibodies

Peking University, May 18, 2020: A joint research team led by Sunney Xie, Director of Beijing Advanced Innovation Center for Genomics (ICG) at Peking University (PKU) has successfully identified multiple highly potent neutralizing antibodies against the novel coronavirus SARS-CoV-2, the causative virus of the respiratory disease COVID-19, from convalescent plasma by high-throughput single-cell sequencing. Generated by human immune system, neutralizing antibodies can effectively prevent viruses from infecting cells. New results from animal studies showed that their neutralizing antibody provides a potential cure for COVID-19 as well as means for short-term prevention. This marks a major milestone in the fight against the pandemic.
