Can sanitizing tunnels be used at building entrances or exits to prevent the spread of COVID-19?
section_content: CDC does not recommend the use of sanitizing tunnels. There is no evidence
that they are effective in reducing the spread of COVID-19. Chemicals used in
sanitizing tunnels could cause skin, eye, or respiratory irritation or damage.

Reviewer feedback on this answer:
Sanitizing tunnels were not mentioned in the question at all and do not have anything to do with the query except for linking it as a possible cleaning agent.
This answer focuses only on how sanitizing tunnels are not recommended but doesn't really talk about any of the alternative methods that are mentioned in the question

How effective are alternative disinfection methods, such as ultrasonic waves, high intensity UV radiation, and LED blue light?
section_content: The efficacy of these disinfection methods against the virus that causes
COVID-19 is not known. EPA only recommends use of the surface disinfectants
identified on List Nexternal icon against the virus
that causes COVID-19. EPA does not routinely review the safety or efficacy of
pesticidal devices, such as UV lights, LED lights, or ultrasonic devices.
Therefore, EPA cannot confirm whether, or under what circumstances, such
products might be effective against the spread of COVID-19.

Reviewer feedback on this answer:
Answer specifically calls out the LED, UV lights, and ultrasonic "devices" in the question and lets the requester know that their efficacy is not known and gives a link to known and trustworthy disinfectants.
It's a decent answer because it mentions the alternative methods from the question and says that the EPA does not test these so it's really unknown as far as those things go

Is contact lens disinfecting solution effective against COVID-19?
section_content: 
Hydrogen peroxide-based systems for cleaning, disinfecting, and storing contact lenses should be effective against the virus that causes COVID-19. 
For other disinfection methods, such as multipurpose solution and ultrasonic cleaners, there is currently not enough scientific evidence to determine efficacy against the virus.


Always use solution to disinfect your contact lenses and case to kill germs that may be present.
Handle your lenses over a surface that has been cleaned and disinfected.

yourself.

website for more information on
healthy contact lens wear and care.

Reviewer feedback on this answer:
Answer mentions "ultrasonic cleaners" but not UV or LED devices but also gives additional information on disinfectant agents that could be used instead. Answer also restricts itself to vision correction aids which is not specified in the question.
This answer is okay even though it only briefly addresses the question by saying these methods are not known to disinfect. Could use more detail but it does answer it
