The notice requires that the relevant units should try their best to control the vehicles and boats going to the epidemic areas and take necessary prevention and control measures for those who have to go to the epidemic areas.

Material 2: At present, Hong Kong will take the fight against influenza A (H 1N 1) as the top priority, and new measures will be introduced and upgraded every day. On Thursday, the SAR Government allocated HK$ 654.38 million+million to 654.38+08 district councils in Hong Kong for epidemic prevention and personal and public health promotion. At the same time, it purchased a batch of masks and distributed them to district councils. The Centre for Health Protection has opened a 24-hour hotline for public enquiries.
