First flows mainly the virus prevails as present influenza of our country
It is reported (the intersection of reporter and Zheng dexterous) On February 8, the report of Beijing, has reported 4 first type H1N1 influenza death cases totally from the beginning of this year; Hong Kong report, influenza peak period has already lasted two weeks, there are 9 people because of the first type H1N1 influenza death from the 24th of January to February 8. On the occasion of national spring transportation at present, first flow and how about it will be the intersection of influenza and overall epidemic situation? February 9, virosis, Center for Disease Prevention and Control of China, prevent and cotrol Deputy Director, national director of influenza in the center researcher Shu YueLong claim, our country has already entered the prevailing peak season of influenza at present. The poisonous Corporation prevails to rely mainly on the fact that first flowed in influenza, but the overall activity level is lower than former years, the epidemic situation is steady.
Shu YueLong introduces, influenza prevails in season in the winter that Northern Hemisphere is in at present, most national influenza activity levels rise to some extent, but is mostly lower than the level of the same period of in the past. In North America, main and popular influenza virus B inferior type for H3N2 type; In Europe, it is mainly first type H1N1 and B type. Already a plurality of countries have reported serious disease and death case caused by first type H1N1 influenza virus at present. In our country, no matter the South or the North, one kind of cases of influenza is in the percentage in the patient of going to a doctor of the door, emergency call, and influenza virus measures the positive rate and is on the rise, but is lower than the level of the same period over the years overallly. Before the end of 2010, the virus prevails to take H3N2 inferior type influenza virus as the core in influenza of our country; Thereafter, first type the intersection of H1N1 and the intersection of influenza and activity strengthen progressively, become, prevail virus mainly already at present. Our country have first flow serious disease behind the case report for 18 weeks in succession will it be August 29 2010, begin to report the serious disease case at the end of 2010, report 129 serious disease cases totally at present, distribute over 23 provinces (market) . On January 16, our country reported first first of this year the death case flows, up to February 8, there are 9 provinces in all in the whole country ' Market) 20 death cases flow to report first totally.
Shu YueLong says, it shows that aetiology of the whole world including our country is monitored, first type H1N1 influenza virus, H3N2 influenza virus and B -type influenza virus, match with poisonous one of component of influenza vaccine that uses at present very good, obvious antigen variation has not happened; The whole the intersection of genome and array analysis find any new mixing the virus again either. The whole world including it shows that our country is able to bear the monitoring result of nature, first type H1N1 influenza virus and H3N2 influenza virus are able to bear medicines to the alkane amine medicine, but it is sensitive to neural amino acid enzyme inhibitor medicine that first type H1N1 influenza virus and H3N2 influenza virus and B -type influenza virus are most.
Shu YueLong thinks, in prevailing season of this influenza, influenza and prevailing peak of our country will not exceed 2009; Will also increase progressively by serious disease and death case that first type H1N1 influenza virus cause, serious disease and death case that will be caused by H3N2 and B -type influenza virus at the same time; Because of the good match of popular virus and vaccine component, inoculating vaccine of influenza will reduce the high-risk group in the danger of prevailing season of influenza effectively.
