For an HCW's consent to be informed, the following should first be explained to them: (a) the risk posed by each of the contagious diseases known at that given time, (b) commonly agreed criteria and definitions of situations that would surpass the SLR, and (c) the fact that there will always be a degree of uncertainty involved with working in the medical profession, as new risks may emerge at any point during one's professional life. If not necessarily when they choose their profession, then at least after being given the relevant knowledge during education and training, the person's choice should be regarded as informed. It should therefore be ensured that HCWs are acquainted with each new and emerging risk, and with any methods of prevention developed during or after their education and training. If a person's choice is to be confidently regarded as informed, it is imperative that these conditions be met. Of course, the question now becomes: how possible is it to satisfy all these conditions?
