The virus is very stable. Transmission can occur by respiratory droplets or via faeces, with swimming pools being a common source of infection. A total of 57 serotypes, grouped into 7 species, have been found in humans; they cause a wide range of illnesses including mild respiratory infections, conjunctivitis and gastroenteritis.
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]
The COVID-19 pandemic in Indonesia is part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was confirmed to have spread to Indonesia on 2 March 2020, after a dance instructor and her mother tested positive for the virus. Both were infected from a ...
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [ 1 ] Examples include the common cold , gastroenteritis , COVID-19 , the flu , and rabies .

Entry, or penetration, is the second step in viral replication. This step is characterized by the virus passing through the plasma membrane of the host cell. The most common way a virus gains entry to the host cell is by receptor-mediated endocytosis, which comes at no energy cost to the virus, only the host cell. Receptor-mediated endocytosis ...
