Enteric fever among Israeli travelers in Nepal: the need for typhoid vaccination.Isr J Med Sci. 1990 Jun; 26(6):325-7.IJ
Enteric fever is still an endemic disease in many developing countries. Most authorities recommend typhoid vaccination for travelers from developed countries to developing countries, particularly in the Indian subcontinent. The Ministry of Health in Israel, however, does not recommend typhoid vaccination to Israeli travelers going to any developing countries. In a study undertaken at a Western-run clinic in Kathmandu, Nepal, we found the rate of typhoid fever infection to be seven times higher among 243 Israeli travelers treated at the clinic for all causes than among 2,866 other Western tourists. The typhoid vaccination rate of the Israeli tourists was 6% compared with 91% for the other Western tourists. We could not detect any differences between the Israeli tourists and the others except for the vaccination status. We conclude that the high rate of enteric fever among Israelis is due to the lack of typhoid vaccination, and we recommend typhoid vaccine for all travelers to the Indian subcontinent.
