What are three main ideas why a HIV positive person would not have to inform their school or job?

im writing a MEL-con essay and that is my topic.
my first reason is that there are privacy issuse. for example its no ones buisness becuase unless there sharing needles, having sex, or exchanging blood, there not going to get hiv from them.
i need to more main ideas why and they have to be general enough for me to elaborate on.
help....

well they dont want to be judged, mistreated, discriminated..my uncle has HIV and he didnt tell us for 7 years nor did he get treated because he was afraid that someone in our city would see him at the place and gossip..we ended up finding out when he was in the hospital and only had 10 T-cells or i think white blood cells..bbut he's okay now and he's on medicine and my thoughts about him havent changed at all

Dear future doctor:

1) Concern over job security and status to stay in school. Most normal people prefer to have someone healthy working by their side. It's just like you don't want to working with someone who is sneezing repeatedly next to you.

2) Protection of personal image and social status, Pride. No one wants to be different and marked a target on their face with " HIV INFECTED". People generally fear the unknown. The witch hunt in the dark ages is a glorified example of what is to be feared by these people.

3) Security Issues. If you are a threat, no matter how rediculous it seems, people will find a way to torment you. It's like a small kid being picked on by a group of bigger kids. People who thinks HIV = death sentence do not want anything to do with those infected and may cause physical as well as emotional damage to those individuals.

Yes there are privacy issues. As a employer, I would rather know then I know what precautions to take and how to hand any emergency. Its just as useful for the person with hiv as it is for someone who doesn't have the virus. If people aren't understanding about this condition, I wouldn't want to work for them. The medical field has come a long way with knowledge for HIV and other std's. I would let the employer know, but, feel its not necessary to tell anyone else.

there is a certain stigma associated with people that have HIV because people are uneducated and some still think a person with the virus can look at you and give it to you

people may discriminate against that person and they may not get a fair chance as other students or employees

if its like a grocery store job or something handling food, people may choose not to eat there because they know an employee is HIV+

First the HIPPA law, we all owe the protect confidentiality to our clients.

There are laws against discrimination, but employers and schools will find other excuses to keep someone out.

Once you put out information you can never take it back and what other people do with it is out of our control
