Rodent-borne disease outbreaks have been linked to weather and climate conditions in a small number of studies published since AR5, but more research is needed in this area. In Kenya, a positive association exists between precipitation patterns and Theileria-infected rodents, but for Anaplasma, Theileria and Hepatozoon, the association between rainfall and pathogen varies according to rural land use types . Weather variability plays a significant role in transmission rates of haemorrhagic fever with renal syndrome  . In Chongqing, HFRS incidence has been positively associated with rodent density and rainfall .
