Hebei's first H1N1 patient concealed his travel itinerary, causing two other people to be infected.

The latest express broadcast from Health Network (http://www.jiankangxinxi.com/) reported: "The first confirmed case in Hebei had a large number of close contacts involving a wide range, mainly because after returning to his home in Cangzhou, he did not stop for a moment and drove himself to 11 places including hair salons, shopping malls, and restaurants. He also visited relatives, friends, and patients, and stayed overnight at a friend's house, resulting in close contacts involving 46 people across four counties and districts."

On the evening of May 22, Yang Xinjian, Director of the Hebei Provincial Health Department, revealed that "this patient had close contact with confirmed cases before returning to China but concealed the journey segment from Melbourne to Hong Kong when entering Beijing, affecting the timely implementation of preventive measures by the Hebei disease control department."

On the evening of May 22, it was learned from the Hebei Province telephone conference on A/H1N1 influenza prevention and control work that due to the concealment of travel history before the onset of illness by the first imported A/H1N1 influenza confirmed patient returning from Australia, and the casual outings to visit friends, there were 46 close contacts. The two newly confirmed cases on the same day were both second-generation cases caused by dining together with this patient. For this reason, the Hebei health department strongly appealed for the voluntary home quarantine of returnees.

On May 21, after being reviewed by the Ministry of Health, the first suspected case of imported A/H1N1 influenza found in Hebei on May 20 was confirmed as a confirmed case. The Hebei health department urgently organized the tracking investigation of close contacts, and 46 close contacts were placed under centralized medical observation, aged between 12 and 70 years old, involving four counties and districts. On May 22, two of the 46 close contacts were confirmed as second-generation cases of the A/H1N1 influenza virus.

Yang Xinjian said that the first imported A/H1N1 influenza confirmed patient in Hebei showed symptoms within 20 hours of entry, and was discovered promptly during the first visit to a community health service station after being asked about their epidemiological history. This type of case has a rapid onset of the virus and strong transmission ability, but generally mild symptoms, with only slight upper respiratory tract infection symptoms besides fever, which can easily be overlooked during diagnosis. He reminded grassroots medical staff to be highly alert to the epidemic, and to inquire in detail about the epidemiological history during monitoring, avoiding adverse effects on prevention and control work due to negligence, and strictly preventing the outbreak of the epidemic in the community.

The Hebei Provincial Health Department once again issued a reminder to overseas students and returnees for the prevention and control of A/H1N1 influenza, requiring them to immediately report to the community service institution or residents' committee, village committee of their place of residence upon returning home, accept health monitoring and health education from local community health service institutions or township health centers, do not go out within seven days, and conduct self-observation at home. Once flu-like symptoms such as fever and cough occur, immediately notify the local disease prevention and control agency by phone, and be transferred to designated medical institutions by special vehicles of the health department for treatment.
