MAHMOUDIYA, IRAQ—As the tumultuous process of reconstruction continues throughout Iraq, health-care workers are still lacking the basic necessities. "Before anything else at all, we need a supply of new, bilingual 'Employees Must Wash Hands' signs," said Youssef Al-Obaidi, director of Mahmoudiya Hospital. "We appreciate the bedding, laundry-sanitization equipment, window glass, penicillin, needles, wall-repair materials, and so on, but without clean hands, none of these mean anything." Al-Obaidi said the importance of hand-washing could not, unlike doctors and nurses, be overstressed.
