What is coronavirus?
Coronaviruses are a large group of viruses that are common among animals. In rare cases, they can be transmitted from animals to humans. The spikes protruding from the virus's membrane look like the sun's corona. It is from this that the virus gets the name 'coronavirus'. It causes illnesses of the respiratory tract, ranging from the common cold to severe conditions like SARS. According to the World Health Organisation (WHO), a novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
What is the difference between Coronavirus and Covid-19
Covid-19 is the disease caused by the novel coronavirus, which originated from China's Wuhan. On February, World Health Organisation (WHO) named the novel coronavirus "Covid-19". "Co" stands for "corona", "vi" for "virus" and "d" for "disease", while "19" was for the year, as the outbreak was first identified on December 31.
According to the WHO, "there are different procedures, and purposes, for naming viruses and diseases.
"Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines."
Viruses are named by the International Committee on Taxonomy of Viruses (ICTV). 
This particular virus was named "severe acute respiratory coronavirus 2" – or SARS-CoV-2.
The WHO says that "from a risk communications perspective, using the name SARS can have unintended consequences in terms of creating unnecessary fear for some populations, especially in Asia which was worst affected by the SARS outbreak in 2003".
Hence, the name 'Covid-19 virus” was given.

How do you catch coronavirus?
Coronaviruses are zoonotic. This implies that they are passed on between animals and people. When Severe Acute Respiratory Syndrome (SARS-CoV) sickened thousands of people around the world — and killed nearly 800 — during a 2003 outbreak, investigations found that it was transmitted from civet cats to humans. MERS-CoV was transmitted from camels to humans. There are several known coronaviruses are circulating in animals that have not yet infected humans. On January 7, the Chinese authorities identified coronavirus (2019-nCoV) as the causative virus behind cases of pneumonia of unknown cause. This novel coronavirus has not been previously identified in humans, hence experts say its too early to figure out the exact cause of the infection.
