The so-far unfounded fear that AIDS can be spread by casual contact has caused some of the victims to be doubly punished, once by a cruel disease, and again by landlords who evict them or friends who shun them.
AIDS does not spread via sharing food, clothes, or via mosquito bite. It also cannot spread aerially. People should avoid unprotected sexual contact by such individuals however any other social contact is perfectly safe.
AIDS patients need compassion. They should not be treated as lepers. When their disease is fully understood, the knowledge gained about immunology and cancer will benefit everyone.
