Keep up with your immunizations. Practice safe sex. Avoid possibly contaminated food and water. Take care when interacting with pets. Don’t share needles or other injection equipment.
If you have HIV, you’re at a higher risk of developing other infections. Since your immune system is weakened, these infections can also put you in danger of developing serious health problems. Ask your doctor about getting vaccines to protect you from infections like the flu, pneumonia, and hepatitis A and B. When getting vaccines, make sure your doctor knows that you have HIV. Some vaccines, such as those containing weakened versions of the live virus, are dangerous for people with weakened immune systems. Having safe sex will not only protect your partner from catching HIV, but will also prevent you from picking up other sexually transmitted infections (STIs). To protect yourself and your sexual partner(s):  Use a condom every time you have sex. If you’re allergic to latex, choose a polyurethane condom. Limit the number of people you have sex with. If you have a lot of sexual partners, you’re more likely to pick up an STI or give one to somebody else. Avoid drinking alcohol or using drugs before having sex. Using drugs or alcohol can impair your judgment and make you more likely to make risky decisions (like not using a condom). Always take your HIV medications while you are sexually active. This will make you less likely to pass an infection to your partner and will also make you less vulnerable to other infections. If you have HIV, you’re more likely to develop serious infections from eating foods that are contaminated with bacteria or viruses. To prevent this, be cautious about what you eat and drink. For example:  Avoid eating raw or undercooked foods. Don’t consume unpasteurized dairy products or fruit juices. Stay away from raw sprouts, such as alfalfa or bean sprouts. Always wash fresh produce, and make sure any equipment or surfaces you use to prepare food are properly cleaned. Drink filtered or bottled water rather than tap water or water taken directly from natural sources, such as lakes or streams. Having HIV doesn’t mean that you have to give up on the benefits of animal companionship. However, you do need to be extra careful not to pick up potential infections or parasites from your pets. Always wash your hands thoroughly with warm water and soap after handling your pets, cleaning animal cages, or changing pet litter. If possible, ask someone else in your home to take care of cleaning litter boxes or pet cages. If you use recreational drugs or any other type of drug or medication that is injected with a needle, never share your needles or syringes with another person. Always use a new needle and syringe. Sharing needles can put you at risk of getting another infection, such as hepatitis. It can also put other people in danger of catching HIV from you.
