What diseases have increased public awareness of infection control over the past few years?

Oh there have been plenty.

STI's for example including HIV (human Immunodeficiency virus) has definitely boosted the awareness of caution and avoiding risky behaviors in both sexual terms and reducing exposure to bodily fluid via blood in work, or IVDA (intravenous drug abuse) needle sharing. 

Additionally potentially dangerous and very infectious diseases like the Flu have put an emphasis on the very basic disease prevention of washing ones hands, covering your sneezes, wearing face masks during exposure, and getting vaccinated as well. 

And these are merely two examples of how hundreds of disease shaped out infection control protocols and norms. 

This is a pretty on point question because all we need to do is replace 's' in the equation with '35'.the calculation will be9.95 + 0.30s = c9.95 + 0.30 (35) = c9.95 + 10.5  = cc = 20.45
