Key Points

Genetic diversity in R. rattus was assessed, revealing higher diversity outside villages which aids dispersal.
Sampling across six villages showed homogeneity in diversity levels, yet lower differentiation inside houses suggests restricted movement.
Findings indicate the need for integrated approaches combining flea control and reducing human-rodent interactions to mitigate plague risk.
Overall genetic differentiation was low, highlighting extensive dispersal and rapid recolonization post-control efforts in the district.
