History

The Sinhalese arrived in Sri Lanka late in the 6th century B.C., probably from northern India. Buddhism was introduced beginning in about the mid-third century B.C., and a great civilization developed at the cities of Anuradhapura (kingdom from circa 200 B.C. to circa 1000 A.D.) and Polonnaruwa (from about 1070 to 1200). In the 14th century, a south Indian dynasty seized power in the north and established a Tamil kingdom. Occupied by the Portuguese in the 16th century and by the Dutch in the 17th century, the island was ceded to the British in 1796, became a crown colony in 1802, and was united under British rule by 1815. As Ceylon, it became independent in 1948; its name was changed to Sri Lanka in 1972. Tensions between the Sinhalese majority and Tamil separatists erupted in violence in the mid-1980s. Tens of thousands have died in an ethnic war that continues to fester. After two decades of fighting, the government and Liberation Tigers of Tamil Eelam began a ceasefire in December 2001, with Norway brokering peace negotiations.

UNAIDS Epidemiological
Fact Sheets

Global Surveillance of HIV/AIDS and sexually transmitted infections (STIs) is a joint effort of WHO and UNAIDS. The UNAIDS/WHO Working Group on Global HIV/AIDS and STI Surveillance, initiated in November 1996, guides respective activities. The primary objective of the working group is to strengthen national, regional and global structures and networks for improved monitoring and surveillance of HIV/AIDS and STIs. For this purpose, the working group collaborates closely with national AIDS programmes and a number of national and international experts and institutions. The goal of this collaboration is to compile the best information available and to improve the quality of data needed for informed decision-making and planning at national, regional and global levels. The Epidemiological Fact Sheets are one of the products of this close and fruitful collaboration across the globe.
