Abstract
Coronaviruses are a major family virus. Some coronaviruses cause disease in humans, and others in animals such as bats, camels, and cats. Human coronavirus usually causes mild illness, such as the common cold. Animal coronaviruses rarely evolve to infect humans and spread among humans, causing severe illnesses such as Severe Acute Respiratory Syndrome (SARS), which appeared in 2002, and Middle East Respiratory Syndrome (MERS). MERS, which appeared in 2012. However, it can be difficult to determine the animal from which a coronavirus infection first starts spreading. In December last year, reports started to emerge that a coronavirus that specialists had never before seen in humans had begun to spread among the population of Wuhan, a large city in the Chinese province of Hubei. Since then, the virus has spread to other countries, both in and outside Asia, leading the World Health Organization (WHO) to declare this as a pandemic. In this article, we try to explain more about this virus, the problems that caused for people and the methods used to diagnose COVID-19.
