- Coronaviruses are a group of viruses that cause diseases in mammals, including humans, and birds. In humans, the virus causes respiratory infections which are typically mild but, in rare cases, can be lethal.
- There are no vaccines or antiviral drugs that are approved for prevention or treatment.
- The genomic size of coronaviruses ranges from approximately 26 to 32 kilobases, the largest for an RNA virus.
- The name "coronavirus" is derived from the Latin corona and the Greek κορώνη (korṓnē, "garland, wreath"), meaning crown or halo. This refers to the characteristic appearance of virions (the infective form of the virus) by electron microscopy, which have a fringe of large, bulbous surface projections creating an image reminiscent of a royal crown or of the solar corona.
- Coronaviruses are believed to cause a significant percentage of all common colds in human adults and children.
- Coronaviruses can cause pneumonia, either direct viral pneumonia or a secondary bacterial pneumonia and they can also cause bronchitis, either direct viral bronchitis or a secondary bacterial bronchitis.
- The much publicized human coronavirus discovered in 2003, SARS-CoV which causes severe acute respiratory syndrome (SARS), has a unique pathogenesis because it causes both upper and lower respiratory tract infections.
- As well as the SARS-Virus the Coronavirus does have a major Outbreak in 2020, therfore everything new will be added later on this site.
