This is not the first time human coronaviruses have emerged
Coronaviruses have emerged a long time ago and never disappeared. Scientists discovered the first coronavirus in 1965 when they cultivated it from a boy with a cold. Then, researchers started to study the virus. As these viruses continued to spread and increase in number and typology, scientists categorized them into a group of viruses known as Coronaviruses. The first discovery of coronaviruses happened more than 50 years ago and they have never disappeared since then. Most likely, they won't end in the future as well.  The first outbreak of coronaviruses occurred in 2002. SARS, a closely related virus, emerged in Southern China and infected more than 8,000 people. People were quick to contain the virus through strict quarantine rules and contact tracing. COVID-19 is more transmissible than 2002-SARS and spreads asymptotically, making it more difficult to control than the 2002 virus. Scientists identified various coronaviruses after 2002. COVID-19 is not the first global outbreak, and future outbreaks are likely to happen following the historic trend of coronavirus outbreaks. 
The outbreak may or may not end depending on the evolution of the virus and human response to it. If the rate of the virus mutation is slow, it might be possible to contain it. If governments establish rigorous policies and people follow orders, the world may succeed in containing the virus. For example, Southern China was able to contain a small coronavirus outbreak in 2002.
