Mathematical modeling of the effectiveness of facemasks in reducing the spread of novel influenza A (H1N1).

摘要: On June 11, 2009, the World Health Organization declared outbreak of novel influenza A (H1N1) a pandemic. With limited supplies antivirals and vaccines, countries individuals are looking at other ways to reduce spread pandemic particularly options that cost effective relatively easy implement. Recent experiences with 2003 SARS 2009 H1N1 epidemics have shown people willing wear facemasks protect themselves against infection; however, little research has been done quantify impact using in reducing disease. We construct analyze mathematical model for population which some during these masks on influenza. To estimate parameter values used effectiveness facemasks, we available data from studies N95 respirators surgical facemasks. The results show if only 20% susceptibility infectivity, 10% would them number cases by 20%. can conclude our that, worn properly, an intervention strategy 2009.
