Xinhuanet, Beijing, January 26 (reporter Lunaud)-national health planning Commission released 26th H7N9 avian influenza human infection diagnosis and treatment programmes (2014) suggested that for the majority of people are now H7N9 avian influenza confirmed sporadic cases, some families get onset phenomenon, but there is no evidence of sustained person-to-person spread; do not rule out limited non-sustained person to person.
Programmes, infection may be carrying H7N9 avian influenza virus in poultry. H7N9 avian flu can be transmitted by respiratory, or in close contact with the secretions or excretions of infected birds acquired infections; and spread to people through contact with contaminated environments. Within 1 week prior to the onset of contact with live poultry or to poultry markets, especially the elderly ones, belonging to the high-risk groups.
According to the findings of the incubation period and the existing cases of influenza, human infection H7N9 avian flu incubation period is 3-4 days. Patients generally manifested flu-like symptoms. In patients with severe disease progression is rapid, 3-7 days of onset of severe pneumonia, mostly sustained in body temperature at 39 ° c or more, breathing difficulties, and sputum may be accompanied by hemoptysis. Often rapid progression to acute respiratory distress syndrome, sepsis, septic shock, multiple organ dysfunction, part of the show such as can occur in patients with pleural effusion. Total number of white blood cells in patients with generic not higher or lower. Critically ill patients have reduced total number of leukocytes and lymphocytes, platelets decreased.
Programme expressly "should be preferred in cases of early recognition of nucleic acid test", and to propose a "negative for pathogen detection, but clinical highly suspected cases, antiviral therapy should remain." Involved in programme development Director of the Peking University first hospital of respiratory medicine of fazheng describes, this is because some of the existing diagnosis of influenza a viral antigen screening sensitivity is not enough.
Programme stressed that early discovery, early reports, early diagnosis, early treatment and strengthening treatment of severe cases, note that both Chinese and Western medicine, is effective prevention, improved cure rates, key to reducing mortality.
新华网北京1月26日电(记者吕诺)国家卫生计生委26日公布的《人感染H7N9禽流感诊疗方案(2014年版)》提出，目前大部分人感染H7N9禽流感确诊者为散发病例，有个别家庭聚集发病现象，但尚无持续人际间传播的证据；不排除有限的非持续的人传人。
方案提出，传染源可能为携带H7N9禽流感病毒的禽类。H7N9禽流感可经呼吸道传播，或密切接触感染禽类的分泌物或排泄物而获得感染；或通过接触病毒污染的环境传播至人。在发病前1周内接触过禽类或者到过活禽市场者，特别是老年人，属于高危人群。
根据流感的潜伏期及现有病例的调查结果，人感染H7N9禽流感潜伏期一般为3至4天。患者一般表现为流感样症状。重症患者病情发展迅速，多在发病3至7天出现重症肺炎，体温大多持续在39℃以上，出现呼吸困难，可伴有咯血痰。常快速进展为急性呼吸窘迫综合征、脓毒症、感染性休克，甚至多器官功能障碍，部分患者可出现胸腔积液等表现。患者白细胞总数一般不高或降低。重症患者多有白细胞总数及淋巴细胞减少，可有血小板降低。
方案明确“在病例早期识别中宜首选核酸检测”，并提出“病原学检测虽为阴性，但临床高度怀疑的病例，仍应当行抗病毒治疗”。参与方案制定的北京大学第一医院呼吸内科主任王广发介绍，这是因为一些现有的甲型流感病毒抗原筛查快速诊断试剂敏感性不够。
方案强调，早发现、早报告、早诊断、早治疗，加强重症病例救治，注意中西医并重，是有效防控、提高治愈率、降低病死率的关键。
