An absence of boarding facilities for high school pupils in Zambia's northern province of Luapula is forcing children to share lodgings with their peers - unsupervised by adults - leading to teenage pregnancies and HIV/AIDS infections. Many children live a long way from school and prefer to rent accommodation nearby. Wamunyima Chingumbe, a Health Ministry director in Mansa District, said the absence of boarding facilities at day schools had led to teenage pregnancies and made pupils vulnerable to contracting sexually transmitted infections (STIs). After malaria, STIs were the most common ailments recorded at makeshift boarding high schools.
