That artical also looks like it was written by a lawyer (no offense ). In real live situations most bacteria and viruses are much easier to kill than we tend to believe. AIDs for instance is a very weak virus it dies in less than a day outside of a host and almost any disinfectant will kill it. Many other dangerous viruses are also as easy to kill. unless you are going from person to person cutting them it is doubt full any razor will spread infection. Of course I'm not a doctor or virologist so your mileage may vary but personally I just clean well with soap and alcohol then stop worrying.
