Empty litter boxes every day, don't just sift. Just like the people living with a person 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 the 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 when handling dirt, and must wash their hands before and after handling dirt. 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. If clothes or sheets have blood, vomit, semen, vaginal fluids, urine, or feces on them, use disposable gloves and handle the clothes or sheets as little as possible. Put them in plastic bags until you can wash them.
