A study involving 209 dosimetry measurements and 100 area measurements in four Swedish paper mills supported the use of dosimetry, in the characterisation of noise exposures in conjunction with sound pressure levels, over sound pressure levels on their own. The analysis showed that dosimetry measures, had the highest estimated validity coefficient (0.70), and that area measurements (0.40) were significantly less accurate at predicting exposure.
Each year the World Health Organization (WHO) puts forward its recommendations for the composition of the influenza virus for the Southern Hemisphere influenza season. This year this includes two influenza A strains and one influenza B strain.
Over the past 10 years, these three recommended strains have accounted for an average of 94% of all influenza cases reported in Australia.
For the 2016 flu season, some manufacturers have chosen to include a fourth strain – an additional influenza B strain.
