Hydroxychloroquine ineffective in animal SARS-CoV-2 infection

A new study by scientists from the U.S and U.K. and published on the preprint server bioRxiv in June 2020 reports that there is no evidence of efficacy for the drug hydroxychloroquine (HCQ) against infection with SARS-CoV-2 in hamsters or macaque models. This finding does not support the current widespread prophylactic and therapeutic use of HCQ in COVID-19.

Factors that determine COVID-19 mortality

A potentially important new study by MIT researchers and published on the preprint server medRxiv* in June 2020 shows that COVID-19 death rates in U.S. states correlate with several factors like commuting to work, temperatures, and geographical location, but not with ICU beds, obesity or poverty. This work, if validated, could help identify the actual contributing factors that shape mortality rates across the USA.
