Everyone is at risk of getting HIV. Preventing exposure for oneself and others is the only way to ensure a safe future.
Abstinence.
To avoid sex is the safest way to prevent infection. To delay sexual relationships during the teen years will also minimise the dangers of multiple, casual sexual encounters.
Faithful Relationship
In a loving relationship both partners must be tested. 
If both are negative and have not been involved in any risky behaviour for at least three months prior to the test, one can be considered safe. If there is any doubt it will be advisable to use condoms until two consecutive tests are negative.
Casual Sexual Encounters
Chances of exposure to HIV is greater if one is exposed to multiple partners. Condoms must always be used for casual sex. Since you cannot see that someone is positive it is always wise to protect yourself in all sexual encounters.
Sexually Transmitted Infections
As soon as one becomes aware of an infection, seek medical advice immediately and get it treated. Both partners must be treated. Any lesion makes the transmission of HIV much easier.
Know Your HIV Status
Make a point of getting yourself tested and also encouraging any sexual partner to get tested. A pregnant lady needs to know her status so that the necessary precautions can be taken to protect her unborn baby if she is positive.
Never Share Needles
A person who chooses to inject drugs can prevent HIV by using clean needles and syringes each time a drug is injected.
Never Share Toothbrushes or Razor Blades.
A chance of exposure is possible through any broken skin or sores.
Handling of Blood or Bodily Fluids
Health professionals care givers and emergency personal etc. must take every precaution to protect themselves if they are at risk of being exposed. Retest yourselves if you are in any doubt. In some risky exposusure situations it may be advisable to double glove. Needle stick exposure needs immediate treatment.
Fights or Violent Encounters.
If you are involved in any fight where skin has been broken and you have been exposed to the blood or bodily fluids of an unknown assailant/ or an assailant whose status is not known to you, get medical assistance as soon as possible. I include rape in this group. Tests and prophylactic antiretroviral medication are usually given at trauma centres.
HIV is not curable but it is preventable!
