Teenagers have a high prevalence of ascariasis in low-income countries with endemic disease, and their hygienic behaviors and access to proper sanitation may be limited in rapidly urbanizing settings. We studied university students in Kabul to estimate the proportion with ascariasis and determine the prevalence of risk factors for infection. Ascariasis was assessed through microscopy for 520 students attending Kabul Medical University. Overall, 15.8% of students were infected. Living in a hostel (21.2% versus 10.4% in houses) using well water (27.7% versus 9.7% for piped water), eating street food (29.4% versus 3.0% for those who do not), and eating unwashed vegetables (63.6% versus 8.8% for those who do not) were risk factors for infection. Recent city migrants who live in group hostels, including students, are important targets for interventions to reduce ascariasis. Such interventions could include encouraging individuals to prepare their own food and use only potable water.
