I was horrified to find out that reusing syringes causes 2 million serious infections across the world each year, including HIV, hepatitis B and C, and even Ebola.
This could all be stopped by switching to smart, single-use syringes that cannot be reused. The World Health Organization hopes that all of the 16 billion injections we get anually will be smart by 2020.
I hope so too, but the smart syringes are more expensive. Given the cost of treating the diseases dirty needles can pass on, it's well worth the investment.
