Tedros Adhanom Ghebreyesus explained: CO for corona, VI for virus, D for disease and 19 for when the outbreak was first identified (31 December 2019). [23] WHO additionally uses "the COVID-19 virus" and "the virus responsible for COVID-19" in public communications. [22] WHO named variants of concern and variants of interest using Greek letters.
The virus can spread to different organs throughout the chicken. [131] The virus is transmitted by aerosol and food contaminated by feces. Different vaccines against IBV exist and have helped to limit the spread of the virus and its variants. [127] Infectious bronchitis virus is one of a number of strains of the species Avian coronavirus. [133]
COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that cases COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection. Molecular tests for viral presence through its ...
Virus infections start when viral particles bind to host surface cellular receptors. [158] Protein modeling experiments on the spike protein of the virus soon suggested that SARS‑CoV‑2 has sufficient affinity to the receptor angiotensin converting enzyme 2 (ACE2) on human cells to use them as a mechanism of cell entry .

Transmissible gastroenteritis virus (TGEV) 1946 (isolated in 1965) [16] Infects pigs, [16] cats, [17] and dogs. [18] Humans: Common cold: Human coronavirus 229E (HCoV‑229E) 1930s (isolated in 1965) [19] Possibly originated from bats. [20] Mice, rats: Encephalitis: MHV-JHM, a strain of murine coronavirus (M‑CoV) named after John Howard ...
The virus has been successfully cultured by Pyrc and coworkers in the ex vivo model of human respiratory epithelium. [7] Additional research has revealed that the virus attaches itself to O-acetylated sialic acids on the cell surface, [8] which instigates a conformational shift in the S protein, facilitating interaction with the entry receptor.
