A total of 139 000 Mozambican babies have been born with the Aids virus in the last six months, according to a report released on Monday by the United Nations Children's Fund.
The same report said that 146 000 pregnant women had been diagonosed as being HIV carriers but a programme of drug treatment had managed to prevent the virus from being transmitted to some of the babies.
Like much of southern Africa, Mozambique is struggling to combat Aids which affects nearly 1.5 million people, around 16.2 percent of the overall population.
Around 20 000 children under the age of five died of Aids in the country last year, according to figures from the health ministry.
