Participants
were
primarily
approached
in
their
homes.
Labor
and
time
constraints
limited
the
area
surveying
to
a
single
pass‐through
of
residential
areas.
Participants
were
surveyed
based
on
their
presence
within
a
home
and
their
willingness
to
participate.
No
willing
participant
was
excluded
from
the
study
unless
they
were
under
the
age
of
18.
Secondary
to
the
door‐to‐door
method,
enumerators
were
placed
at
high‐traffic
locations
within
each
survey
area.
LABB
and
Tulane
staff
members
selected
stationary
team
placements
based
on
their
evaluation
as
a
viable
location
and
permission
from
the
location
owner.
Examples
of
viable
high‐traffic
areas
were
grocery
stores
and
convenience
stores.
