Officials were told to review measures against infectious diseases amid recent outbreaks and fears on hygiene. A motion, sponsored by Chan Kam-lam of the Democratic Alliance for the Betterment of Hong Kong (DAB), was carried after securing the support from the Liberal Party and the Association for Democracy and People's Livelihood. Members of the Democratic Party and the Frontier were at the candlelight vigil in Victoria Park. Mr Chan urged the Government to plug loopholes in legislation and strengthen co-operation between the Department of Health and the two municipal services departments. This would enhance responsiveness in monitoring and containing infectious diseases such as cholera, measles and German measles, he said. 'The DAB thinks the Government should set up a food authority, with members from the two municipal councils, the Department of Health and the two municipal services departments,' Mr Chan said. 'This will help centralise the monitoring power and strengthen the legislative and law-enforcing work related to food safety,' Mr Chan said. In view of the recent cholera cases, the Government was urged to take a series of measures to safeguard public health. Health chiefs were scrambling to work out the logistics of blitzing nearly 2,000 schools in an emergency measles vaccination campaign before the summer holidays. The 734 kindergartens, 608 primary schools and 479 secondary schools will be visited by immunisation teams before November in the $15 million campaign.
