AN ESTIMATED 128000 or 20% of some 640000 teenagers in Kenya’s secondary schools are infected with the HIV virus, Education Minister Kalonzo Musyoka said on Thursday. Most secondary school pupils in Kenya are aged between 14 and 17. President Daniel arap Moi last November declared Aids, which kills an estimated 500 Kenyans every day, a national disaster, and but declined to advocate condom use to fight the epidemic. Between 13 and 14 percent of all adults in Kenya, about 1,9-million people, are infected with HIV, according the health ministry. As many as 760000 Kenyans have already died of the disease.
