請閱讀下面短文，并按照要求用英語寫一篇150詞左右的文章．
    Much is unknown about how COVID-19，a new coronavirus，spreads．Current knowledge is largely based on what is known about similar coronaviruses．Coronaviruses are a large family of viruses that are common in many different species of animals，including camels，cattle，cats，and bats．Rarely，animal coronaviruses can infect people and then spread between people such as with MERS，SARS，and now with COVID-19．
    Most often，spread from person-to-person happens among close contacts （about 6 feet）．Person-to-person spread is thought to occur mainly via respiratory droplets （呼吸飛沫） produced when an infected person coughs or sneezes，similar to how influenza and other respiratory pathogens （病原體） spread．These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs．It's currently unclear if a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth，nose，or possibly their eyes．
    It's important to note that how easily a virus spreads person-to-person can vary．Some viruses are highly contagious （傳染性）（like measles），while other viruses are less so．There is much more to learn about the transmissibility severity，and other features associated with COVID-19．
