The disease caused by the new coronavirus

The epidemiological investigation of the first cases pointed to the visit to a wholesale seafood and wildlife market in Wuhan as a link, suggesting that the new coronavirus could have been initially transmitted to humans from an animal source. Inter-human transmission (person-to-person) was quickly proven and is responsible for the continued spread of the disease. was officially called by the WHO as Coronavirus Disease 19 (COVID-19, for short) and, in parallel, the virus was renamed to SARS-CoV-2.
Etiological agent of COVID-19 The causative agent lis nimewo whatsapp of COVID-19 is a new coronavirus, SARS-CoV-2. Viruses of the coronaviridae family can cause infections in vertebrate animals. In humans, coronaviruses cause respiratory infections of varying severity, being one of the most common agents of the common cold (HCoV-229E, HCoV-NL63, HCoV-OC43 and HCoV-NKUI) and also recognized causes of severe pneumonia such as respiratory syndrome acute severe (SARS, for Severe Acute Respiratory Syndrome, described in 2002 and the Middle East Respiratory Syndrome (MERS, for Middle East Respiratory Syndrome, described in 2012), respectively caused by SARS-CoV and MERS-CoV.
Bats appear to be the primary source (reservoir) of several variants of coronavirus and are also likely to be for SARS-CoV-2, as suggested by phylogenetic studies in progress with the genome of the new coronavirus. However, it is likely that for humans to be infected, another animal host (still unknown for SARS-CoV-2) is involved, as demonstrated for SARS-CoV (civets) and for MERS-CoV (dromedaries).Si ou bezwen ilistrasyon syantifik, isit la se kote a, nou gen literalman dè milye de ilistrasyon syantifik pou ou, ki gen ladan plizyè sijè nan Biyoloji, Syans Lavi, Syans Sante ak Medsin.
