A critical problem associated with UV disinfection systems, in general, is the lack of testing using the specific human pathogens that are deemed to be UV resistant. The main issue resides in the differences in UV susceptibility between the non-pathogenic surrogates that are typically utilized in UV disinfection testing and the pathogens they are representing. For adenovirus this is particularly problematic as it is considered one of the most UV resistant human pathogens. Adenovirus requires several fold higher UV doses than other microorganisms to achieve a 4log reduction. In addition, even after UV exposure the virus may still release its

一般来说，与紫外线消毒系统相关的一个关键问题是缺乏使用被认为具有紫外线抗性的特定人类病原体进行的测试。主要问题在于紫外线消毒测试中通常使用的非致病性替代物与它们所代表的病原体之间的紫外线敏感性差异。对于腺病毒来说，这尤其成问题，因为它被认为是最抗紫外线的人类病原体之一。腺病毒需要比其他微生物高几倍的紫外线剂量才能实现 4log 的减少。此外，即使在紫外线照射后，病毒仍可能释放其病毒。
