Coronaviruses: These respiratory viruses are responsible for the COVID-19 pandemic as well as other diseases including MERS, which was first reported in 2012, and SARS, which caused a global ...
The earliest reports of a coronavirus infection in animals occurred in the late 1920s, when an acute respiratory infection of domesticated chickens emerged in North America. [15] Arthur Schalk and M.C. Hawn in 1931 made the first detailed report which described a new respiratory infection of chickens in North Dakota.
SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of SARS-CoV-2 that is considered most plausible by the scientific community.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Coronavirus disease 2019 (COVID-19) Yes: Coxsackie B virus: Coxsackie B virus infection Enterovirus infection is diagnosed mainly via serological tests such as ELISA and from cell culture. There is no well-accepted treatment for the Coxsackie B group of viruses. Under research [10] PRNP
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal.
Coronaviridae is a family of enveloped, positive-strand RNA viruses which infect amphibians, birds, and mammals.Commonly referred to as coronaviruses in the English language, the family coronaviridae includes the subfamilies Letovirinae and Orthocoronavirinae; the latter also known as coronavirinae.
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
