Results: Detection and treatment of TB cases
Countries reporting to WHO
By the end of 2003, 201(96%) of 210 countries and territories reported case notifications for 2002 and/or treatment outcomes for patients registered in 2001. We received reports from all 22 HBCs.
DOTS population coverage, 1995-2002
The number of countries implementing DOTS increased by 25 during 2002, bringing the total to 180 out of 210 (Figure 1). One hundred and twenty-one countries determined that DOTS was available to over 90% of their populations (Figure 2 , Annex 5). Just one DOTS country had coverage under 10% (Turkey), and 58 were in the expansion phase (coverage 10-90%). All 22 HBCs had a DOTS programme in 2002. Nine countries implemented DOTS for the first time in 2002; five achieved moderate coverage (10-90%), and three reached high coverage (> 90%).
DOTS population coverage has steadily increased since 1995 (Figure 2 ; Table 4). By the end of 2002, 69% of the world's population lived in counties, districts, oblasts, and provinces of countries that had adopted DOTS. Reported coverage was over 70% in the WHO regions of Africa, the Americas, the Eastern Mediterranean and the Western Pacific, and lowest in the European Region (40%, Figure 3).
All 22 HBCs provided data on detection and treatment from DOTS programmes covering at least part of the country. Ethiopia, South Africa, and Thailand reported that coverage increased to more than 90% of their populations. Afghanistan, Pakistan, Ethiopia, South Africa, all improved coverage by more than 20% between 2001 and 2002, Thailand by 18%, China by 10%, and India by 7% (Table 4).
