conclusions
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

what s new about this research
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

slide4

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

slide5

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

slide6

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

malaria deaths before age 70 in the study
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

Malaria mortality rates were high in early childhood and in later middle age

Half of the malaria deaths were in a few high-malaria states in eastern India

* Malaria death rates, India 2005, standardised to population aged 0-69

slide12
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

slide13

Malaria deaths occurred where the most dangerous type (Plasmodium falciparum) of malaria parasite occurs

CGHR.ORG

slide14

Malaria deaths did not occur in states where dengue or meningitis or typhoid * were common (1)

* These diseases can be confused with malaria

fever deaths in india 2005 age 70 n 1 8m 18 lakh
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

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

slide22

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
