I'm not sure I'm ready to accept the fact that having rights restricted is a body autonomy issue outside of being in solitary confinement. I commented in a different thread about "exigent conditions" which sometimes can trump personal liberties or even body autonomy when the "greater good" is concerned. If I'd entertain your statement as being on topic, I'd say that national measures in a global pandemic fit that.
I could argue the opposite. If your purported "exception" applies to 80%+ of the global population, a minimal dash of common sense would make me think that's the rule, not the other way around.
I think the draft qualifies as "exigent conditions" in which some rights and ethics get suspended in favour of the "greater good", or if you mean mandatory military service, I think most western nations stopped having that. Do you have something more mundane in mind?
[edit] To answer your question: yes, there are only 66 countries with mandatory military service. Among the Western democracies there are the Nordics, Estonia, Austria and Greece. From here: https://worldpopulationreview.com/country-rankings/countries...
The ethical system on which modern Western societies are built allows for body autonomy, while at the same time covers some corner cases: war, pandemic, etc. The fact that there are exceptions doesn't somehow invalidate the basics.
