How do we correctly translate the XKCD comic snippet "Good News: You recently had close contact with someone who has not tested positive for COVID"? I feel this XKCD comic:


Good News: You recently had close contact with someone who has not tested positive for COVID.
cropped from XKCD comic 2342: Exposure Notification

is incorrectly translated:


好消息：您最近并未与任何确诊新冠肺炎的患者密切接触。
cropped from XKCD comic 2342 translation: Exposure Notification

As I understand this translation means:

Good News: You recently had no close contact with anyone who has tested positive for COVID.

which ruins the joke.  The user should have had close contact with people who have not tested positive.  And each message should refer to an individual (unidentified) person.
Question: How do we correctly translate this snippet from the XKCD comic into Chinese?
My attempt:

好消息：您最近与某个无确诊新冠肺炎的人密切接触。

Although I'm not 100% comfortable with this, as it sounds like the person has &quot;undiagnosed COVID&quot;, and using 确诊 (instead of 诊断) indicates a formal confirmation of a diagnosis, whereas the person may not have even been tested.
I would translate it as such:

好消息：你最近密切接触到测试新冠肺炎未测出阳性的人


Using 接触到 removes the need to introduce other complements with 与 / 和 / 跟， which reduce fluency of the joke. It also removes the negation from the main verb, just as in the English original.
未测出阳性 renders more literally &quot;not tested positive&quot; instead of 无确诊, which doesn't sound very grammatical to me (better with 未, by the way)
I wouldn't use 确诊 anyway, because it literally means &quot;confirmed (case)&quot;, as in 确认诊断，and the joke is more about the test result, not the diagnosis.
新冠肺炎 in your attempt, is accurate, as it identifies the pulmonary inflammation, i.e. the disease, whereas other frequently encountered terms as 新冠病毒 refer to literally the &quot;new coronavirus&quot;, i.e. the vector.
某个～人：this term 某 as in 某人 / 某个人 does translate to &quot;someone&quot; according to dictionaries. However in my experience, the usage of 某 is slightly different than that. I think the most accurate translation is &quot;a certain person&quot;. So yes, it's an unnamed person, a &quot;someone&quot;, but it implies that you choose to not disclose their identity. An example can be found in newspaper articles, when referring to someone involved in a crime. The perpetrator or the victim can be referred to as &quot;Surname + 某&quot;, e.g. 张某, literally &quot;a certain Zhang&quot;. I'm not fully sure the &quot;someone&quot; in the XKCD cartoon is actually this kind of &quot;someone&quot;. If it is, then 某个人 might be appropriate. Otherwise just 人 also works.


With all that said, I'm afraid this won't sound equally humorous in Chinese... but that's my personal opinion.
