Porcine epidemic diarrhea virus (PEDV) 1971 [25] Infects pigs. Caused outbreaks in 1972 [26] and 1978, [27] 2010, 2013, 2014, and 2015. [28] Dogs Enteritis: Canine coronavirus (CCoV) 1971 Cats Feline infectious peritonitis (FIP) Feline coronavirus (FCoV) Cattle: Enteritis: Bovine coronavirus (BCV or BCoV) Humans Severe acute respiratory ...
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 .

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]
In January 2020, the World Health Organization (WHO) recommended 2019-nCoV [35] and 2019-nCoV acute respiratory disease [36] as interim names for the virus and disease per 2015 guidance and international guidelines against using geographical locations or groups of people in disease and virus names to prevent social stigma.
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.
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 ...
Human coronavirus OC43 [1] (HCoV-OC43) is a member of the species Betacoronavirus 1, which infects humans and cattle. [2] [3] The infecting coronavirus is an enveloped, positive-sense, single-stranded RNA virus that enters its host cell by binding to the N-acetyl-9-O-acetylneuraminic acid receptor. [4]
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.
