Each year around 130,000 families face the risk that a baby will contract HIV from its mother during pregnancy, birth or breastfeeding. Antiretroviral treatment given to mothers can greatly reduce mother-to-child transmission, and this has spared roughly 230,000 children each year. The approach has been one of the most effective interventions in global HIV prevention. Progress depends on access to testing and drugs in lower-income countries. The figures show how a medical advance has changed outcomes for families worldwide.

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.
