In hospitality and food industries it should be compulsory. In areas where there is potential for wounding yourself with sharp utensils someone with hiv could be potentially and selfishly be spreasing their diseases to many others. Futhermore why do people with aids shake others hands and sometimes insist on doing so?. What if they did have a small cut and not realise it. Is it worth harming others to feel not discrimated against. Aids is a truelly horrible disease but not disclosing hiv is not about issues concerning stigma or privacy in such industries. Aids should be disclosed it is about having respect for others lives. In my opinion anyone who is infected should respect the lives of others, and take responsibility for themselves and their actions for once; like choosing jobs that are safe etc...sleeping around sharing needles and unsafe sex all reflect a lack of respect one has for their own self and these values should not be shared. It is completely negligent to potentially harm others. Yes, people should keep their diseases to themselves in environments where they could be fatal. Anyone who spreads the disease is a selfish murderer as far as I am concerned. All humans need to learn the three R's . . . Respect for oneself; Respect for others; Responsibility for all my actions, and other life ...and that ignorance is not bliss.
