In addition to cleaning and disinfecting, what can I do to decrease the spread of disease in my workplace?
section_content: Employers can also:

Provide tissues and no-touch disposal receptacles.
Provide soap and water in the workplace. If soap and water are not readily available, use alcohol-based hand sanitizer that contains at least 60% alcohol. If hands are visibly dirty, soap and water should be chosen over hand sanitizer.
Place hand sanitizer in multiple locations to encourage good hand hygiene practices.
Place posters that encourage staying home when sick, the importance of hand hygiene, and coughing and sneezing etiquette at the entrance to your workplace and in other workplace areas where employees are likely to see them.
Discourage handshaking


Reviewer feedback on this answer:
Doesn't mention cleaning or cleaning services at all.
This talks about various things that the employer can do to help but doesn't talk about cleaning staff at all, let along a special cleaning staff that's being asked about

page_title: What Transit Maintenance Workers Need to Know About COVID-19
section_headers: Which transit vehicle surfaces should be cleaned? What are the best cleaning chemicals to use when cleaning?
section_content: Perform routine cleaning and disinfection of all frequently touched non-porous
surfaces within the interior of the transit vehicle on a daily basis and, in
particular, before maintenance workers conduct repairs such as removing or
repairing seats. These surfaces can include hard seats, arm rests, door
handles, seat belt buckles, light and air controls, adjacent walls and
windows, and grab handles. If the surfaces are visibly dirty, they should be
cleaned prior to disinfectant application. For soft or porous surfaces, remove
any visible contamination if present and clean with appropriate cleansers
indicated for use on these surfaces.
Appropriate disinfectants include:


EPA’s Registered Antimicrobial Products for Use Against Novel Coronavirus SARS-CoV-2, the cause of COVID-19, are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method, and contact time). A list of products with EPA-approved emerging viral pathogens claims is available at:
https://www.epa.gov/pesticide-registration/list-n-disinfectants-use-against-
sars-cov-2external icon.


Diluted household bleach solutions prepared according to the manufacturers label for disinfection can be used if appropriate for the surface. Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.

Alcohol solutions with at least 70% alcohol.

Wear the personal protective equipment (PPE) required for using the cleaning
and disinfection products according to the product manufacturer’s
instructions. After removing PPE, employees should wash their hands with soap
and water for at least 20 seconds. Work uniforms worn during cleaning and
disinfecting should be laundered afterwards. If possible, launder
items
using the warmest appropriate water setting for the items and dry items
completely. Clean hands after handling laundry by washing hands with soap and
water or using an alcohol-based hand sanitizer with at least 60% alcohol if
soap and water are not available.

Reviewer feedback on this answer:
Has detailed cleaning instructions, but doesn't specifically address whether a special crew is needed.
This talks about how to clean but doesn't address the question that asks if they need a special cleaning staff. There's nothing about that in here.

Who should clean and disinfect community spaces?
section_content: Regular cleaning staff can clean and disinfect community spaces. Cleaning
staff should be trained on appropriate use of cleaning and disinfection
chemicals and provided with the personal protective equipment (PPE) required

Reviewer feedback on this answer:
Clearly address the question of whether special cleaning crews are necessary.
This does answer the question although doesn't go into much detail. It states that regular cleaning staff should be sufficient. That answers the question
