| Abstract: | Murine typhus occurred in 254 individuals in Kuwait between April and August 1978; 81% of patients were aged between 15 and 44 years, and 63% were male. The highest attack rate occurred among people in the lowest socioeconomic class. The outbreak coincided with a period of high rat and flea density. A study of the first 104 cases suggested that infection was acquired in the home, but a case — control study revealed no significant differences between patients and control subjects in terms of exposure to rats or domestic animals, and other factors. This suggests that murine typhus is hyperendemic rather than epidemic in Kuwait. The disease is being controlled through reduction of both flea and rat populations. Murine typhus may be much more common in many areas than is generally realized, and its status should be re-evaluated regularly in all known and potential foci. |
