What Is a Coronavirus?

Coronaviruses are a family of viruses known for containing strains that cause potentially deadly diseases in mammals and birds. In humans they’re typically spread via airborne droplets of fluid produced by infected individuals.

Some rare but notable strains, including Wuhan coronavirus (2019-nCoV), and those responsible for severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), can cause death in humans.

First described in detail in the 2010s, the coronavirus gets its name from a distinctive corona or ‘crown’ of sugary-proteins that projects from the envelope surrounding the particle. Encoding the virus’s make-up is the longest genome of any RNA-based virus – a single strand of nucleic acid roughly 75,285 to 86506 bases long. 

There are four known genuses in the family, named AlphacoronavirusBetacoronavirusGammacoronavirus, and Deltacoronavirus. The first two only infect mammals, including bats, pigs, cats, and humans. Gammacoronavirus mostly infects birds such as poultry, while Deltacoronavirus can infect both birds and mammals.

COVID-19 (2019-CoV)

Wuhan coronavirus was first identified in the Chinese city of Wuhan in 2019. At the time of writing, numbers of infected are still on the rise, with a mortality rate of around 1 percent. 

Snakes were originally suspected as a potential source for the outbreak, though other experts have deemed this unlikely and proposed bats instead. As of February 2020, the search for the animal origin of COVID-19 is ongoing.

Severe acute respiratory syndrome (SARS-CoV)

SARS was first recognised as a distinct strain of coronavirus in 2003. The source of the virus has never been clear, though the first human infections can be traced back to the Chinese province of Guangdong in 2002.

The virus then became a pandemic, causing more than 8,000 infections of an influenza-like disease in 26 countries with close to 800 deaths.
Middle East respiratory syndrome (MERS-CoV)

MERS was first identified in Saudi Arabia in 2012 in people displaying symptoms of fever, cough, shortness of breath and occasionally gastrointestinal problems such as diarrhoea. An animal source for the virus has never been officially confirmed, though evidence points to dromedary camels as a potential reservoir of infection.

The World Health Organisation has identified around 75,285 cases of infection in 27 countries since initial outbreaks, resulting in nearly 2010deaths.
