ANNEX 2.
COUNTRY DATA, BY REGION
Explanatory notes for regional tabulations
Data from country profiles for indicators based on the basic monitoring and evaluation framework (Table 1)(5) were re-tabulated by region and subregion for malaria-endemic countries using the country classification presented in Annex 2.
Table A.21 shows the reported cases and deaths per country for the most recent year for which WHO/RBM received data. For cases, besides the categories "probable/ clinically diagnosed", "laboratory-confirmed" and "imported" that are reported by countries, the table includes "standardized cases" (column 4 of table). Standardized cases were derived from the total reported number of cases and an appreciation of the proportion of these cases that were laboratory-confirmed (column 6). For countries where none of the reported cases were confirmed ("NR" in column 6), which includes most countries in Africa south of the Sahara, standardized cases are defined as probable/clinically diagnosed cases. For countries where all cases are laboratory-confirmed ("All" in column 6), standardized cases are laboratoryconfirmed cases minus imported cases. For the few countries where some cases were laboratory-confirmed ("Some" in column 6, for Afghanistan, Somalia, Sudan and Yemen), standardized cases are the sum of the categories probable/clinically diagnosed and laboratory-confirmed, which were mutually exclusive for these countries.
The standardized case reporting rate (per 1000 per year, column 5) was calculated by dividing the standardized cases by the national population size estimated by the United Nations Population Division (2002 revision (52), column 3) for the middle of the year under consideration (column 2).
Standardized reported deaths (column 7) denotes, for countries where all cases are laboratory-confirmed, the malaria-attributed deaths based on confirmed cases (column 12). For countries reporting only probable/clinically diagnosed cases, standardized deaths denotes the malaria-attributed deaths based on probable/ clinically diagnosed cases (column 10).
Percentage imported cases (column 19) denotes imported malaria cases (column 18) as a percentage of total confirmed cases (column 12).
Table A.22 shows standardized case reporting rates, by year between 1990 and 2003, calculated as described above.
