in a cautionary corollary, in the United States some jurisdictions allow persons who spread disease to be charged criminally; a few jurisdictions have allowed charges to be brought even though the infecting person has not been diagnosed, did not display outward symptoms of infection and infected others without intent to infect. Irregardless[sic] of the likely success of such a prosecution it seems to me the prudent course of behavior would be to minimize the risk of prosecution in the first place.

In addition to potential criminal liability such an infected person will also have potential civil liability for negligently infecting others (a greater likelihood than criminal charges). I would not want to be in the shoes of someone who refused to be screened and then is found to have infected others.....
