The Ministry of health will revise the diagnostic criteria for human avian influenza

Introduction: yesterday, Qi Xiaoqiu, director of the disease control department of the Ministry of health of China, said that from the two aspects of clinical symptoms and epidemiological investigation, two cases in Hunan were consistent with the performance of human infection with highly pathogenic avian influenza, but the final results need to be confirmed by laboratory test reports Qi Xiaoqiu said that according to the recommendation of who experts, the Ministry of health will make further changes to the previously issued diagnostic standard for human highly pathogenic avian influenza Qi Xiaoqiu said that when the center for Disease Control and prevention of Hunan Province began to detect the cases of unexplained pneumonia, the samples were negative However, for the sake of prudence, the Ministry of health sent professionals from the National Center for Disease Control and prevention to carry out further tests It was found that the two cases could not be completely excluded from the judgment of the laboratory Qi Xiaoqiu introduced that three aspects of evidence are needed to judge whether a case is avian influenza: the first is clinical symptoms, the second is epidemiological investigation data, and the last and most fundamental is laboratory test evidence "At present, according to the results of clinical symptoms and epidemiological investigation, two cases of he's brother-in-law in Hunan Province are quite related to avian influenza." Qi Xiaoqiu explained that the so-called "quite relevant", that is to say, from the former two aspects, it is very consistent with the performance of avian influenza Qi finally said that whether the two cases in Hunan are avian influenza or not, it is necessary to wait for the final laboratory test results of CDC in China There are two reasons why the sampling is not accurate Qi Xiaoqiu explained that the reason for this is that there was no such case in the local area, and the level of basic level technicians is limited On the other hand, there may be some problems in the sampling samples during the course of the disease Qi said that one of the reasons for the inaccuracy of sampling is the inaccuracy of sampling location and method, and the second is the lag of sampling time If it is in the early stage of the disease, it is impossible for people to produce antibodies, but if the sampling is delayed, the patient will produce antibodies, and the final test results will show positive Wang Chen, President of Chaoyang Hospital in Beijing, is also one of the invited experts in the case investigation of Hunan Province by the Ministry of health Among the three cases in Hunan Province, song of Yisuhe town in Xiangtan County has ruled out the possibility of avian influenza, Wang Chen told the newspaper yesterday At present, China CDC is conducting a comprehensive micro antibody test on two cases of he's brother and sister in Hunan Province Test standard will be modified in details Qi Xiaoqiu, director of the disease control department of the Ministry of health, told reporters yesterday that the Ministry of health had issued the diagnostic standard for highly pathogenic avian influenza in human infection in the first half of this year However, due to the wide coverage of grass roots in China's rural areas and insufficient training of health and epidemic prevention personnel, there is a gap between the operation level of grass-roots technical personnel and the standard requirements Qi Xiaoqiu said that because the pneumonia girl in Hunan was cremated in a hurry after her death and the sampling was not enough, it brought a series of difficulties to the laboratory test after that To this end, the Ministry of Health recently issued a notice requiring local health departments to strengthen the monitoring of suspected cases of human infection with highly pathogenic avian influenza, while emphasizing the requirements of timely collection and proper retention of samples Qi Xiaoqiu said that since no human cases of avian influenza have been found in China, according to the recommendation of who experts, the Ministry of health will make further changes to the previously issued diagnostic standard for human highly pathogenic avian influenza As for the specific changes, Qi said that it is mainly to absorb the experience of other countries with human cases of avian influenza and make some detailed changes.
