自2009年3月以来,首先发生在美国和墨西哥的新型甲型H1N1流感疫情迅速波及全球。中国科学家,包括流行病学家、病毒学家和临床医生深入研究疾病规律,并取得了可喜成绩。中国卫生部新型甲型H1N1流感专家组组长王辰教授领导课题组克服各种困难,及时总结了中国新型甲型H1N1流感早期病例的临床特征。他们发现,中国应对新发传染病的措施是及时有效的,病情早期的病例症状多数较轻,大约33%的患者没有发热症状,实时逆转录聚合酶链反应(PT-PCR)方法病毒核酸阳性持续中位时间约为6d。年龄小于14岁、男性、症状发生48h后才接受奥司他韦治疗均为病毒核酸持续检测阳性的独立危险因素。 Since March 2009, the first outbreak of the new type A (H1N1) virus in the United States and Mexico has rapidly spread to the world. Chinese scientists, including epidemiologists, virologists and clinicians, have conducted in-depth studies on disease laws and have achieved gratifying results. Professor Wang Chen, leader of the new type A H1N1 influenza team led by the Chinese Ministry of Health, led the task force to overcome various difficulties and summarized the clinical features of the early cases of new type A (H1N1) flu in China in time. They found that China’s response to a new outbreak of infectious disease was timely and effective. Early symptoms of the disease were mostly mild, with about 33% of patients without fever. Real-time reverse transcription polymerase chain reaction (PT-PCR) was used to detect positive viral nucleic acid The sustained median time is about 6d. Age less than 14 years of age, male, symptom onset after 48 hours after receiving oseltamivir treatment are viral continuous positive detection of independent risk factors.
