而且，患者到医院可不仅仅会携带手机。他们的衣服、鞋子和钱包等都会携带各种各样的微生物。天晓得，有的人甚至会带着咖啡杯到医院，这可真是雪上加霜，因为每一杯星巴克（Starbucks）拿铁咖啡都是“可能致癌”的。病原体还会随着访客的物品潜入到医院。我简直不敢建议人们去研究这些病原体。想想看，访客到医院探访病人，把自己的物品扔到床上，然后还会与病人热情地接吻。简直令人作呕。

    至于手机致命论，如果WHO能将注意力转移到更直接的手机病原体威胁上或许更有趣：也就是说每一位走进医院大门的患者、护士和医师都会携带可能致命的细菌。不仅如此，基于手机的全新医疗技术正逐渐被医院所采用，但是供应商对感染风险的认知并不一致。有些供应商孜孜以求，以确保其设备在各病房之间能非常方便地进行清理；而有些供应商只求把手机应用程序卖给医院了事，根本不关心手机本身是否可以方便地进行消毒，后果自然堪忧。

    乔纳森•萨米特博士是美国南加利福尼亚州大学（University of Southern California）内科医生及流行病学家，并在世界卫生组织下属的一个委员会担任主席。正是该委员会将手机划入“可能致癌”类别。近期他曾表示：“如今，我们的孩子可能一生大部分时间都在使用手机或者其他类似的产品。我们确实需要了解它们是否具有致癌风险，或是其他任何风险。”

    或许，所谓“其他风险”我们早已心知肚明。

    And by the way, patients show up at hospitals with far more than their cell phones. They carry in all manner of organisms on their clothes, shoes and purses, among other things. God knows they may even show up with coffee cups, which could be the double whammy given the "potentially carcinogenic" risk of every Starbucks Latte on earth. I'm almost afraid to suggest that someone study the pathogens that trail into the hospital on the stuff belonging to people who visit patients, drop their stuff on the bed and give them a nice juicy kiss. Nasty.

    But as to the "deadly" cell phone controversy, it would be interesting to turn WHO's attention to what might be the more immediate cell phone risk: The fact that every patient, nurse, and physician who walks through the hospital door is carrying a potentially lethal set of germs. Not only that, but a whole new generation of cell phone-based medical technology is coming to hospitals and not every vendor is thinking about the infection risk equally. Some are committed to ensuring that their devices can be readily cleaned between patient rooms while others are just selling cell phone apps into hospitals without concern for whether the handsets themselves can be readily disinfected, consequences be damned.

    Dr. Jonathan Samet, a University of Southern California physician and epidemiologist and chairman of the World Health Organization committee that deemed cellphones as "potentially carcinogenic" was quoted recently as saying: "We've hit the point where today's children are going to use a cellphone or something like a cellphone for most of their lives. We do need to understand if there is a risk of cancer or anything else."

    It is possible that the "anything else" might already be known.
