With the poultry workers, 59 had been male and much more than 60 have been aged 550 years (mean age 52 years, variety 173 years) in LPVs and 54 years (range 249 years) in PFs. Many of the subjects had worked in the poultry business for much more than 10 years (LPVs 86 , PFs 79 ) and had close make contact with with poultry every day (LPVs 90 , PFs 94 ). The majority of LPVs and PFs had not received H5N1 and/or seasonal influenza vaccines throughout the two years prior to the specimen collection date. For NPWs, the ages ranged from 21 to 88 years (mean age 53 years). Their education level was higher (P 05) than that of poultry workers. Additional than 50 of the NPWs received seasonal influenza vaccines in 2010 and/or 2011, whereas the H5N1 vaccination coverage was nonetheless low. Overall, a higher proportion of PFs didn’t use private protective equipment (PPE) in comparison with LPVs (LPVs: two , PFs: 12 ; two = 27, P 0001). In the PPE made use of, probably the most common were gloves, boots and masks.S. Y. Huang and othersTable 1.
