Rodents are known reservoir hosts for many pathogens that can cause disease in humans. The risk of zoonotic spillover is high in informal urban settlements (slums) where rodents and human densities are high, rodents live in close proximity to humans and human knowledge of disease risks and access to health care is limited.
