Migrant workers queue for medical checkup at a hospital in Beijing June
2, 2003. Local authorities have ordered all migrant workers who are
working in China's capital to obtain health certificates from hospitals
as a measure to control the spread of SARS. In Beijing, which has
handled more SARS cases than any other city on earth, the World Health
Organisation (WHO) said it was encouraged by the fall-off in numbers of
cases and said it was aiming to eliminate SARS rather than just control
it. REUTERS/Guang Niu
