general knowledge of the killer behind pneumonia and streptococcus influenza
June 11 of 2009, World Health Organization (WHO) Claim to warn the rank of first type H1N1 influenza and rise to 6 grades. This means first type H1N1 influenza epidemic situation has already developed into globally " Influenza prevails big " ,Threaten human health seriously. With influenza being high to send season, close on, how use medical resource fully, lower influenza to the greatest extent mortality to deserve question which people think thoroughly.
Serious the intersection of disease and influenza can cause death, the intersection of death and reason, patient of influenza, include, take place influenza virus infect, continue, send bacterial infection with virus, infect, lead to the fact basic disease aggravate originally usually. Among them, bacterial pneumonia is the most important reason of dying of illness to carry on and take place in influenza, the pneumonia streptococcus continues the most important etiology of bacterial infection of the hair. So, people should pay attention to preventing and controlling the science that the pneumonia streptococcus infects when great in the face of influenza to prevail. But it's a pity, this is often ignored.
Infect the pneumonia streptococcus - -It is the important reason why influenza is lethal
Erupt influenza simultaneously pneumonia to divide clinically into the following three: Primary influenza virus pneumonia, caused by virus, is usually called simple viral pneumonia, quite rare; Continue hair nature bacterial pneumonia, after influenza virus is infected and lightened, continuing the taking place bacterial infection causes, clinical and difficult at this moment to isolate influenza virus, clinical manifestation is a serious disease sometimes; Virus and bacterium's mixing pneumonia, the simultaneous bacterium that the virus infects is infected with repeatedly, clinic can isolate the virus, clinical manifestation is mostly serious diseases.
The pneumonia streptococcus is the important pathogens with lethal influenza, epidemiology evidences are numerous previously
In 1918, studied to reveal, 20%- 25% of the soldiers suffered from influenza in multiple epidemiology about American military camp influenza, among them 12%- 28% erupt the pneumonia simultaneously, the case fatality rate is 20%- 50% (only a report is 4%) ,The phlegm or nasopharyngeal sample trains the separating rate of streptococcus of pneumonia to be 26%- 41%, the death case lung tissue up to 28%- 67% or heart blood sample isolates the pneumonia streptococcus.
