恐慌

為了避免恐慌，專家對病毒的變種風險隻字不提。正因為變種，新型冠狀病毒才會由小型哺乳類動物間傳播，變成動物傳人，再變成人傳人。下一步的基因洗牌，無人能預測。第二點是傳播途徑，現時已經證實的有飛沫、接觸以及糞口傳播。CDC不排除非典是經空氣傳播，而有專家指出新型冠狀病毒的傳播速度比非典更高。所以，新型冠狀病毒能否經空氣傳播，是未知之數。

Some viruses are highly contagious (like measles), while other viruses are less so. It’s not clear yet how easily 2019-nCoV spreads from person-to-person.

In addition, it is possible that SARS-CoV might be spread more broadly through the air (airborne spread) or by other ways that are not now known.
