Nanfang Daily (Reporter/Xiang Yuhang Deng Xiang) H7N9 avian influenza is a new type of avian influenza, which was first discovered in Shanghai and Anhui at the end of March 2013. H7N9 avian influenza is the first new subtype of influenza virus discovered in the world. Yesterday morning, the Shenzhen Centers for Disease Control and Prevention held a press conference stating that Shenzhen has not detected H7N9 influenza virus in the population so far. The detection of influenza-like cases in Shenzhen has been normal this year, and the number of hospitalized patients with pneumonia in the city has not increased significantly. It is reported that the disease control has included the new virus into the city's influenza surveillance targets, and the CDC also urges citizens to avoid contact with and eat sick and dead poultry and livestock when going out on a clear day.

No significant increase in hospitalized patients with pneumonia

According to the influenza surveillance this year, data from the city's influenza surveillance sentinel hospitals show that the current percentage of outpatient fever and flu-like cases is about 3.6-4%, which is slightly lower than the percentage in previous years during this season. Ma Hanwu, deputy director of the Shenzhen Centers for Disease Control and Prevention, revealed that the number of hospital admissions due to pneumonia in the city has not increased significantly, with 10-20 patients in all hospitals in Shenzhen every week.

Since March every year, the intensity of influenza in Shenzhen has begun to increase, and the flu has become active. Years of influenza surveillance data in Shenzhen show that the peak of influenza is between May and July each year. At present, the disease control department has set up 39 monitoring sentinels, including hospitals, social health centers, schools, poultry farms, and wholesale markets, to sample and detect influenza viruses every week to grasp the latest influenza epidemic.

Ma Hanwu said that humans have been infected with H7N2 and H7N3 avian influenza viruses in the Netherlands, Italy and other countries, but H7N9 is currently the world's first case. He also warned the public that the current H7N9 avian influenza infection situation is not terrible, because it rarely occurs in humans, and it is still a bird flu virus circulating among poultry, so there is no need to panic. He said that at present, it is not clear how the virus infects people. The current attitude is: report, investigate, treat and deal with infected animals or people, and conduct medical research. The technology platform and research level of influenza detection can control the epidemic situation in the bud in time.”

Tomb-sweeping day is approaching, Ma Hanwu reminded citizens to educate children to avoid contact with animals when sweeping tombs or outings in the suburbs. Dead birds and poultry found should be reported to the management department. They must not be handled privately, let alone killed for food. Meat and poultry that have passed quarantine purchased on the market can be handled in accordance with hygiene requirements and do not interfere with ordinary consumption. He suggested that citizens can boost their immunity by injecting general vaccines.

The reporter also learned that the Shenzhen Inspection and Quarantine Bureau will pay close attention to the development of the epidemic, carry out influenza monitoring at various ports in Shenzhen, strengthen the temperature monitoring and medical inspection of passengers entering and exiting the country, and report the suspected infectious disease in time and take corresponding measures.

At the same time, it will also focus on the use of electronic display screens, publicity boards, bulletin boards and other forms to report the human infection H7N9 avian influenza epidemic situation, and carry out targeted preventive measures and knowledge education; set up consultation posts for inbound and outbound passengers Necessary health advice and health consultation.
