The species was merged with Rat coronavirus (discovered in 1970 [23]) and Puffinosis coronavirus (discovered in 1982 [59]) as Murine coronavirus in 2009. [60] 229E and OC43 were collectively named Human respiratory virus but merged as Human coronavirus 229E (HCoV-229E) in 2009. [61]
The specimen came to be known as the Beaudette strain. In the late 1940s, two more animal coronaviruses, JHM that causes brain disease (murine encephalitis) and mouse hepatitis virus (MHV) that causes hepatitis in mice were discovered. [19] It was not realized at the time that these three different viruses were related. [20] [12]
The timeline of the COVID-19 pandemic lists the articles containing the chronology and epidemiology of SARS-CoV-2, [1] the virus that causes the coronavirus disease 2019 and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2]
A study by Scripps Research Institute reports that COVID-19 may be mutating in Florida, making the virus more likely to infect cells. [91] During the month of June the seven day moving average of new COVID-19 cases in Florida increased nearly ten-fold, from 726 new cases per day on June 1 to 7,140 new cases on July 1, 2020. [5]
The world's first COVID-19 drug designed by generative AI is approved for human use, with clinical trials expected to begin in China. The new drug, ISM3312, is developed by Insilico Medicine. [389] A new AI algorithm developed by Baidu is shown to boost the antibody response of COVID-19 mRNA vaccines by 128 times. [390]
