| T19 |
0-164 |
Sentence |
denotes |
Coronaviruses (CoVs) are enveloped, positive-sense, single-stranded RNA viruses that belong to the subfamily Coronavirinae, family Coronavirdiae, order Nidovirales. |
| T20 |
165-310 |
Sentence |
denotes |
There are four genera of CoVs, namely, Alphacoronavirus (αCoV), Betacoronavirus (βCoV), Deltacoronavirus (δCoV), and Gammacoronavirus (γCoV) [1]. |
| T21 |
311-477 |
Sentence |
denotes |
Evolutionary analyses have shown that bats and rodents are the gene sources of most αCoVs and βCoVs, while avian species are the gene sources of most δCoVs and γCoVs. |
| T22 |
478-575 |
Sentence |
denotes |
CoVs have repeatedly crossed species barriers and some have emerged as important human pathogens. |
| T23 |
576-901 |
Sentence |
denotes |
The best-known examples include severe acute respiratory syndrome CoV (SARS-CoV) which emerged in China in 2002–2003 to cause a large-scale epidemic with about 8000 infections and 800 deaths, and Middle East respiratory syndrome CoV (MERS-CoV) which has caused a persistent epidemic in the Arabian Peninsula since 2012 [2,3]. |
| T24 |
902-1201 |
Sentence |
denotes |
In both of these epidemics, these viruses have likely originated from bats and then jumped into another amplification mammalian host [the Himalayan palm civet (Paguma larvata) for SARS-CoV and the dromedary camel (Camelus dromedarius) for MERS-CoV] before crossing species barriers to infect humans. |
