Patient zero is an idiom referring to the first individual affected or identified in an outbreak of a disease or epidemic. While it might evoke scenes from a dystopian thriller, the term has real-world significance and is notably linked to the AIDS epidemic in the 1980s.
An idiom is a phrase where the words don’t mean exactly what they say. Idioms make the English language interesting and can tell us a lot about history and culture.
Ever wondered why we say “patient zero” instead of simply the “first sick person”? Dive into its fascinating history, learn its proper usage, and embrace the beauty of idioms that make our language so vivid. Keep reading, and embark on this enlightening journey!
Patient Zero Meaning Explained
What does patient zero mean? Imagine it as the starting point of a disease—the first person identified in an outbreak. They’re the ones who inadvertently set off a chain reaction of illness.
Science-wise, tracing a disease or virus back to the very first case can help doctors and scientists figure out how it began and how to treat it. Without patient zero, they’re lost.
I don’t know about you, but all I can think of is The Walking Dead when I hear the term patient zero! I was a huge fan of the graphic novels before the show became a hit, and they used the term quite a bit in the book series.
Is It Patient 0 or Patient Zero?
Although patient zero sounds cooler and is more commonly used in literature and the media, technically speaking, the term can also be written as patient 0.
The numeral 0 here signifies that the person is the starting point. So, whether you spell it out or use a numeral, remember that you’re referring to the same unlucky individual.
Origin and Etymology of Patient Zero Idiom
The term “patient zero” is somewhat of a newcomer in our history. It gained popularity during the AIDS crisis in the 1980s. Gaëtan Dugas, a French-Canadian flight attendant, was wrongly dubbed as Patient O (the letter O referring to Outside of California).
However, a mix-up in communication led many to misinterpret the “O” as a zero, suggesting that Dugas was the very first case of the HIV epidemic in the U.S. That’s quite a weighty and distressing label to bear. Despite subsequent research debunking this notion, the term “patient zero” persisted and is now commonly used to describe the initial case in an outbreak.
