The virusvirus vi·rus | \ ˈvī-rəs : a disease-causing agent that is too tiny to be seen by the ordinary microscope, that may be a living organism or may be a very special kind of protein molecule, and that can only multiply when inside the cell of an organism is now known as the severe acute respiratory syndromeSARS (severe acute respiratory syndrome) ˈsärz : a severe respiratory illness that is caused by a coronavirus (species Severe acute respiratory syndrome-related virus of the genus Betacoronavirus), is transmitted especially by contact with infectious material (such as respiratory droplets or body fluids), and is characterized by fever, headache, body aches, a dry cough, hypoxia, and usually pneumonia — called also severe acute respiratory syndrome coronaviruscoronavirus co·ro·na·vi·rus : any of a family (Coronaviridae) of single-stranded RNA viruses that have a lipid envelope studded with club-shaped projections, infect birds and many mammals including humans, and include the causative agents of MERS, SARS, and COVID-19 2 (SARS-CoV-2SARS-CoV-2 ˈsärz-kō-ˈvē-ˈtü : the coronavirus (Severe acute respiratory syndrome coronavirus 2 of the genus Betacoronavirus) that is the causative agent of COVID-19). The disease it causes is called coronavirus disease 2019 (COVID-19COVID-19 \ ˈkō-vid-nīn-ˈtēn : a mild to severe respiratory illness that is caused by a coronavirus (Severe acute respiratory syndrome coronavirus 2 of the genus Betacoronavirus), is transmitted chiefly by contact with infectious material (such as respiratory droplets), and is characterized especially by fever, cough, and shortness of breath and may progress to pneumonia and respiratory failure. ). Coronaviruses are an extremely common cause of colds and other upper respiratory infections. More than 200 types of viruses what we call a “cold,” but the most common one is the rhinovirusrhinovirus rhi·no·vi·rus | \ ˌrī-nō-ˈvī-rəs : any of a genus (Rhinovirus) of picornaviruses including two (species Human rhinovirus A and Human rhinovirus B) having numerous serotypes causing respiratory infections (such as the common cold) in humans, which is thought to be responsible for at least 50% of colds. Other viruses that can cause colds include coronavirus, respiratory syncytial virussyncytial virus : a paramyxovirus (species Human respiratory syncytial virus of the genus Pneumovirus) that is responsible for severe respiratory diseases (such as bronchopneumonia and bronchiolitis) in children and especially in infants —abbreviation RSV, influenzainfluenza in·flu·en·za | \ ˌin-(ˌ)flü-ˈen-zə : an acute, highly contagious, respiratory disease caused by any of three orthomyxoviruses: (1) or influenza A : moderate to severe influenza that in humans is marked especially by sudden onset, fever, sore throat, fatigue, muscle aches, inflammation of the respiratory mucous membranes, and cough, that has numerous variants caused by subtypes (such as H1N1, H2N2, or H3N2) of an orthomyxovirus (species Influenza A virus of the genus Influenzavirus A) infecting humans and various animals (such as birds or pigs), and that may occur in ... and parainfluenzaparainfluenza para·in·flu·en·za | \ ˌper-ə-ˌin-flü-ˈen-zə : any of several paramyxoviruses (genera Respirovirus and Rubulavirus) that are a frequent cause of infections (such as croup) of the lower respiratory tract especially in infants and children.
SARS-CoV-2 = Name of virus
CoVid 19 = Name of disease caused by SARS-CoV-2
In most sites discussing this topic, the names are used interchangeably.
Most people who catch the CoVid 19 recover at home, and some need hospitalization to fight the virus. In roughly 3-4% of people COVID-19 is deadly. Medical authorities aren’t sure of the fatality rate of the coronavirus, because they’re not certain how many people have become infected with the disease. But they do have some estimates, and there is a widespread consensus that COVID-19 is most dangerous for elderly patients and those with preexisting health burdens. The virus causes respiratory illness (like the flu) with symptoms such as a cough, fever and in more severe cases, pneumonia. The main cause of disease and death is called severe acute respiratory syndrome for which the SARSSARS särz : a severe respiratory illness that is caused by a coronavirus (species Severe acute respiratory syndrome-related virus of the genus Betacoronavirus), is transmitted especially by contact with infectious material (such as respiratory droplets or body fluids), and is characterized by fever, headache, body aches, a dry cough, hypoxia, and usually pneumonia — called also severe acute respiratory syndrome virus got its name.
