Using census data we identify
geographic patterns in residency changes in Lesotho over a decade. Using
kriging to spatially interpolate data from 8,510 households we identify regions
where households have members temporarily living away from home (divided
households). Further, using a multivariate analysis and data from 2,026 couples
we determine whether a partners’ absence increases the likelihood of having
extramarital partners and/or risk of HIV infection.
Approximately 40% of
individuals moved between 2001 and 2011; mainly to, and within, urbanized
regions. Many households are divided: ~40% have members elsewhere in Lesotho,
~30% in South Africa (SA). Geographic patterns are apparent; they differ based
on where the household member is living. Many couples were temporarily
separated: ~50% of wives, ~20% of husbands. Separation was not a risk factor
for HIV. Only men were more likely to have extramarital partners if their
spouse was away: ~1.5 times if in Lesotho, ~3 times if in SA.
The high degree
of geographic mixing necessitates synchronizing interventions within Lesotho,
and with SA, to successfully reduce transmission. It will be challenging to
reduce concurrency in men with wives away from home. Our results are
generalizable to other sub-Saharan countries where residency changes are common.
