For just COVID?
HIV?
Herpes (can be spread without being symptomatic)?
Ringworm?
Flu?
I will withdraw Ringworm and substitute West Nile Virus.
Airborne infectious disease that represents a threat to society at large just by the presence of an infected human spreading it in public. The Supremes have weighted in twice on this. Your attempt at strawman is noted.
Smallpox, Ebola, tuberculosis, COVID to name a few that would fall under what the Supremes have weighted in on or would fall under an existing ruling especially given the constitutionally declared state of emergency still in effect from the last admin.
