大流行病與一般的流行病有哪些不同？
不管什么時(shí)候，只要是某種疾病的病例超過了一般人們所料想的，這就可以稱為普通流行病。傳染性疾病的流行能夠升級(jí)至大流行疫情，但也不總是這樣。
How does a pandemic differ from an epidemic?
An epidemic occurs whenever the number of cases of a particular disease exceeds the number that would normally be expected. Epidemics of infectious disease can escalate into pandemics, but do not always do so.
