The selected Q&A of Webinar: Infection prevention& control in Taiwan

Mediland Livestream webinars: infection prevention& control in Taiwan was round-off smoothly! We appreciate all participators and each precious question had been raised online.
We listed down the highlight questions and solutions abstracted from the Livestream sections for your inspiration.

Q : Is there any evidence on the effectiveness of UVC on COVID-19 prevention?

A : Yes. UVC has been clinically proven that it can inactivate SARS-CoV-2 effectively.

 
Q:  Which no-touch methods will you choose to use during covid-19, HPV or UVC? Why?

A : For my opinion, I will choose UVC. HPV has a good result to disinfect the entire room. In some cases, for example, in BMT ICU, it would be a tool that we can use to fight against HAI. However, there are still some disadvantages of HPV. It will take hours to use VHP, which means we can’t use it frequently. And also, we have to remove curtains, devices and seal the whole room. Very inconvenient! UVC also are effective to kill the pathogens. Moreover, the process can be completed in 5 to 15 mins, which is more suitable for current situation that we have to clean and disinfect the environment very often.

 
Q : Are there any toxic chemical residuals after UVC or HPV process?

A : Hyper Light UVC system won’t produce toxic chemical residuals after process; however, some UV system might generate ozone.
HPV will be decomposed into water and oxygen if react completely. However, healthcare workers should be care of the remained HPV, which could induce inhalational injury easily. Be sure the concentration of HPV reduced to safety level before enter to the process area.

 
Q : Based on my understanding, UVC disinfection has yet to be included in CDC’s guideline of environmental cleaning and disinfection. How do you convince your hospital to utilize this kind of technology in your environmental hygiene protocol?

A : CDC takes years to collect and review scientific data and evidence before they revise the guidelines and introduce new methods. However, COVID-19 is an emergency situation. According to current data, we are confident that using UVC disinfection device with enough output should be effective to kill pathogens on the target surface and improve environment hygiene. That’s why we include UVC to our environment hygiene protocol to reduce healthcare-associated infection in the hospital.

Q: What's the difference between UVC disinfection system and pulsed-xenon disinfection system? Which will you suggest to use?

A: Pulsed-xenon system generates full-spectrum light, including UVA, UVB, UVC, to kill the pathogens. However, when talking about germicidal efficacy, UVC system is clinically proven that its efficacy is much better than pulsed-xenon system. Therefore UVC should be the better choice.

Q: Why should you use UVC from Mediland instead of others? what makes it different from other UVC?

A: The main difference between UVC systems is efficacy. Hyper Light generates higher UVC output than most of its competitors. Moreover, with Protective Reflector Technology, UVC energy can be reflected and increased when delivered to the target surface. That’s why Hyper Light can achieve quick disinfection process with great germicidal efficacy. The efficacy has been clinically proven by medical centers and 3rd parties.

 
Q: Can rapid test replace PCR test in COVID-19 diagnosis?

A: It depends. PCR test can be used to effectively diagnosis patients during the period of infection. Rapid test via IgM can be used in the early stage of infection, and test via IgG can be used only after the patients infected for a while or recovery.
