染有愛滋病的血在衫上凝固了,在洗衣機中會否被洗掉和愛滋病菌會否死掉?

應該可以的，但要小心。以下摘自美國官方的疾病控制中的「單張」，應該可信的：


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. You can but you don't need to add bleach to kill HIV; a normal wash cycle will kill the virus. Clothes may also be dry cleaned or hand-washed. If stains from blood, semen, or vaginal fluids are on the clothes, soaking them in cold water before washing will help remove the stains. Fabrics and furniture can be cleaned with soap and water or cleansers you can buy in a store; just follow the directions on the box. Wear gloves while cleaning. See the section on gloves for more information on types of gloves.
