Wear rubber gloves when you clean up after pets and wash your hands before and after cleaning. Empty litter boxes every day, don't just sift. Just like the people living with AIDS, pets need yearly checkups and current vaccinations. If the pet gets sick, take it to the veterinarian right away. Someone with AIDS should not touch a sick animal.
Gardening can also be a problem.
Germs live in garden or potting soil. A person with AIDS can garden, but they must wear work gloves while handling dirt and must wash their hands before and after handling dirt. You should do the same. Laundry Clothes and bed sheets used by someone with AIDS can be washed the same way as other laundry. If you use a washing machine, either hot or cold water can be used, with regular laundry detergent.
