Question: How should wildfire agencies screen for the virus?

Answer passage (source: CDC):
page_title: FAQs for Wildland Firefighters
section_headers: In many situations, fire personnel travel from many different geographic locations and live and work closely in shared living spaces, such as bunkhouses, during the fire season. In these situations, how do you prevent infection and spread of COVID-19 for co-workers or crewmates?
section_content: When personnel arrive to their duty stations, it is recommended that
management provide separate spaces for the personnel to socially
distance themselves from others on their crew for 14 days,
if possible. During this period, personnel should take special precautions to
limit any close interactions with other people (maintaining at least 6-feet
distance) and avoid sharing kitchens, living spaces (bedrooms), bathrooms, or
household items.
If shared living spaces and common areas must be utilized during the initial
14 day period after reporting, all personnel should still practice social
distancing (maintaining at least 6 feet distance from one another), wear
cloth face coverings, and frequently clean and
disinfect shared and high touch surfaces. Personnel should also
consider sleeping in opposite directions (head to toe) and avoid using bunk
beds in shared sleeping quarters. Management should also consider increasing
ventilation rates and/or the percentage of outdoor air that circulates within
the shared living and working areas.
When feasible, management should employ mechanisms to support their employees
and limit employees’ interactions with others during this period. This may
include online ordered and delivered groceries, delivered meals, and virtual
and online training tasks.
After the initial 14-day period is over, fire crews and modules who work
together and do not have regular interactions with other people can isolate as
a unit. During this time, personnel should continue to cover their mouth and
nose with tissue or elbow when they cough or sneeze, perform proper hand
hygiene and frequently clean and
disinfect shared spaces,
vehicles, and equipment with EPA-registered
disinfectantsexternal icon that are appropriate for the surface and
effective against SARS-CoV-2, following label instructions. If a crew operates
as a unit, it is not necessary for crew members to wear face coverings unless
they are not feeling
well or interacting with the public (consistent with CDC
guidelines for households living in close
quarters). If interactions with the general public must occur, all
personnel should practice social distancing, wear cloth face coverings,
perform hand hygiene, and disinfect surfaces, objects, or items that are
shared with the general public.

Housing.
