ADULT AND CHILD MALARIA MORTALITY IN INDIA Sources of support: ICMR and RGI (India); FIC, NIH (US); LKSKI, IDRC & CIHR (Canada); CTSU & MRC (UK) Prabhat Jha, on behalf of MDS Collaborators Prabhat.jha@utoronto.ca CGHR.ORG
Conclusions • Malaria deaths should not occur with basic health services: prompt diagnosis and treatment are effective • India had over 200,000 avoidable malaria deaths (55,000 child, 30,000 at ages 5-14, 120,000 ages 15-69) in 2005 • Reconsider WHO total of 5,000 child and 10,000 adult malaria deaths in India and 100,000 adult malaria deaths worldwide CGHR.ORG
What’s new about this research? • Large, nationally representative sample of all deaths based on household interviews with families • The study results reflects the whole of India • This is NOT a study of properly treated malaria patients (in whom few deaths occur) CGHR.ORG
Nationally representative sample (Sample Registration System) • 6,671 of these small areas randomly chosen from all parts of India (each with about 1000 people per area) CGHR.ORG
How was the study done? 800 Registrar of General India field workers interviewed 122 thousand families of people who had died in 2001-2003 Written reports each coded independently by at least two physicians to attribute a probable cause to each death (i.e. malaria) Coded malaria deaths likely represent malaria, despite the potential for misclassification CGHR.ORG
How was the study done? Calculate proportion of malaria deaths in each age group within the study Combine with national 2005 UN totals of deaths in each age group Produce national (and state) estimates of numbers of malaria deaths at various ages CGHR.ORG
Malaria-attributed deaths in the present study by age 3·6% at ages 1 month-69 years CGHR.ORG
Malaria deaths before age 70 in the study • 90% (2422/2685) were in rural areas • 86% (2315/2685) did not occur at a health facility CGHR.ORG
Malaria-attributed deaths: estimated national totals, by age 120 thousand at ages 15-69 CGHR.ORG
Malaria mortality rates were high in early childhood and in later middle age * Study-attributed Indian malaria mortality rates WHO indirect estimates of Indian malaria mortality rates Age-specific all-India malaria-attributed death rates estimated from the present study, and those estimated indirectly for WHO *No. of study deaths per age class (in red) CGHR.ORG
Half of the malaria deaths were in a few high-malaria states in eastern India ~100 * Malaria death rates, India 2005, standardised to population aged 0-69 CGHR.ORG
Risk of a newborn Indian dying from malaria before age 70(at current rates, in the absence of other disease) • About 2% overall in India • Over 12% in Orissa CGHR.ORG
Malaria deaths occurred where the most dangerous type (Plasmodium falciparum) of malaria parasite occurs CGHR.ORG
Malaria deaths did not occur in states where dengue or meningitis or typhoid * were common (1) * These diseases can be confused with malaria CGHR.ORG
Malaria deaths did not occur in states where dengue or meningitis or typhoid * were common (2) * These diseases can be confused with malaria CGHR.ORG
Fever deaths in India, 2005< age 70, n=1.8M (18 lakh) • 1.3 M (13 lakh) UNDIAGNOSED, mostly untreated FEVER deaths in RURAL India • Malaria is a significant minority of these fever deaths, but more so in high-malaria states CGHR.ORG
Conclusions • Malaria deaths should not occur with basic health services: prompt diagnosis and treatment are effective • India had over 200,000 avoidable malaria deaths (55,000 child, 30,000 at ages 5-14, 120,000 ages 15-69) in 2005 • Reconsider WHO total of 5,000 child and 10,000 adult malaria deaths in India and 100,000 adult malaria deaths worldwide CGHR.ORG

Key messages • First nationally representative study of the causes of all deaths in India • Of 75 342 study deaths at ages 1 month to 70 years, 2681 (3.6%) were attributed to malarial fever • Malaria caused about 200 thousand (2 lakh) deaths before age 70 in 2005in India as a whole • This is far more than the WHO estimate of only 15 thousand at all ages • Of malaria deaths: • 55 thousand <age 5 years • 30 thousand at 5-14 years old • 120 thousand (1.2 lakh) in adults 15-69 years old • Malaria mortality rates were high in early childhood and in later middle age CGHR.ORG
Key messages • 90% of malaria deaths were in rural areas and 86% were not in any health facility • Half the malaria-attributed deaths were in a few high-malaria states in eastern India (Orissa, Chhattisgarh, Jharkhand, Assam and its smaller neighbours) • At current malaria death rates, an average Indian baby would have a 2% chance of dying from malaria before age 70, but this risk is much greater in the high-malaria states • Malaria deaths occurred in the states where the Indian malaria control program finds a high prevalence of the most dangerous type (Plasmodium falciparum) of malaria parasite CGHR.ORG
