“零號病人”指的是第一個得傳染病,並開始散播病毒的患者。在流行病調查中,也可叫“初始病例”或“標識病例”,正是他造成了大規模的傳染病暴發。
其在傳染病的發生發展和傳播過程中以及傳染病的認知、研究過程中佔有重要的地位。
零號病人有哪些醫學意義?
1、能夠鎖定傳染源,比如是否接觸了什麼動物?
2、鎖定傳播方式,比如跟動物是如何接觸的?
3、瞭解流行病史,瞭解到病毒在人體的潛伏期有多長?
4、如果將零號病人的親密接觸者納入觀察範圍,就能對病毒的傳播力有所判斷?
5、如果零號病人本身沒有發病,作為無症狀攜帶者,他是如何對病毒免疫的?
那麼為什麼不叫1號病人呢?這個不得而知,估計是因為零號病人是源頭的原因吧。

因為第一個感染的病人沒有人知道,也沒有人發現這種病毒,所以叫做零號病人。
在醫院被醫生診斷下,確診是病毒傳染,那麼被稱為新型冠狀病毒

“零號病人”這種表述實際上最初是基於一種誤解,原文是“Patient O”,“O”代表“Out of”,在1984年疾病控制與預防中心(CDC)的研究中,最早記錄的艾滋病毒患者被代號為“患者O”,代表“患者離開加利福尼亞”(patient O", which stands for "patient Out of California".) 。但是,報告的某些讀者將字母O解釋為數字0。隨後,由舊金山紀事報記者和作家蘭迪·希爾茨(Randy Shilts)傳播了“零號患者”("Patient Zero")。
該術語已擴充套件為一般用法,是指被標識為人群中傳染病的第一攜帶者(主要病例)或災難性趨勢發作時的第一事件。
"Patient Zero" was used to refer to the supposed[7] source of HIV outbreak in the United States. The expression is actually based on a misunderstanding: in the 1984 study of Centers for Disease Control and Prevention (CDC), one of the earliest recorded HIV-patients, Gaëtan Dugas, was code-named "patient O", which stands for "patient Out of California". The letter O, however, was interpreted by some readers of the report as the numeral 0. The designation "Patient Zero" (for Gaëtan Dugas) was subsequently propagated by the San Francisco Chronicler journalist and author Randy Shilts in his 1987 book And the Band Played On, on which see further below.
The term has been expanded into general usage to refer to an individual identified as the first carrier of a communicable disease in a population (the primary case), or the first incident in the onset of a catastrophic trend.

0是最小的自然數,也是升序排在最前面的自然數 好的遙控器都從0頻道開始排列,函式的引數也是從0開始往後排,比如三個引數,就是0,1,2,而非1,2,3
