Severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) are two highly transmissible and pathogenic viruses that emerged in humans at the beginning of the 21st century. Both viruses likely originated in bats, and genetically diverse corona …

The family tree also gives insight into the geographic origins of these viruses, Wells said. So far, all ACE2-using viruses have been detected in Yunnan province, implying that SARS-CoV-2 did not originate in Wuhan, where the first cases of COVID-19 were reported, but elsewhere in China. One unanswered question is, why did SARS-CoV-2 emerge now?

This process of changing and selection of successful variants is called “virus evolution.” Some mutations can lead to changes in a virus’s characteristics, such as altered transmission (for example, it may spread more easily) or severity (for example, it may cause more severe disease).

In one scenario, the virus evolved to its current pathogenic state through natural selection in a non-human host and then jumped to humans. This is how previous coronavirus outbreaks have emerged, with humans contracting the virus after direct exposure to civets (SARS) and camels (MERS).

Human Middle East respiratory syndrome is a zoonotic respiratory disease caused by Middle East respiratory syndrome coronavirus (MERS-CoV) originating from camels in the Arabian Peninsula. While there are a large number of camels in East Africa, often traded to the Arabian Peninsula, no autochthonous human MERS-CoV case is...

The coronavirus was first reported in China in 2019, spread to all parts of the world as global COVID-19 cases are nearing the grim milestone of 100 million. Even though it is a well-known fact that viruses mutate, SARS-CoV-2, the virus that causes COVID-19 has become more transmissible with experts still investigating how it became more infectious.

Coronaviruses are a large family of viruses. Some coronaviruses cause cold-like illnesses in people, while others cause illness in certain types of animals, such as cattle, camels, and bats. Some coronaviruses, such as canine and feline coronaviruses, infect only animals and do not infect people.
