In order to prevent the world spread of the current H1N1 influenza virus, China has activated an emergency mechanism and established a multi-level body to enhance monitoring, prevention, inspection and quarantine. Moreover, China has been in frequent communication with the World Health Organization and some of the countries involved to trace the outbreaks and enhance prevention of the H1N1 influenza A virus. At present, there has been no confirmed case of swine flu in mainland China.
On the night of May 1st, the first H1N1 flu case in Hong Kong was confirmed, after which China went on high vigilance against the possible spread of the virus. To ward off the threat of an epidemic, the Chinese government issued an urgent message that all disease inspection organizations at international airports should enhance their prevention and control against H1N1 flu to cut its access into China. All international airports must prepare well for emergencies and report regularly to the government about their status. The Chinese government has suspended flights from Mexico to Shanghai since May 2nd and the government of Mexico and relevant airline companies were notified. When the flights will be resumed depends on the status of the pandemic.
The international airports of Beijing, Shanghai, Shenzhen and Hong Kong have started to take urgent prevention measures already. All tourists must fill in a Health Declaration Form and tourists from Mexico will be quarantined for 7 days. "The measures are not targeted at Mexican citizens, and are not discriminatory. This is purely a question of health inspection and quarantine,” Foreign Ministry Spokesman, Ma Zhaoxu said. All packages from infected areas must be inspected and quarantined, and any pork in imports will be examined strictly.
Because of the tightened quarantine procedures against H1N1 influenza at international airports, entering or leaving China may take much more time. Therefore, more airport staff have been called in to help passengers to be processed quicker.
