Outline
Theburden and public health impact of malaria in children
Clinical
presentation
Recognition/clinical diagnosis
Approach to treatment
Burden
In Uganda, U5 child can have 6 episodes of
clinical malaria
Malaria accounts for about 70% of outpatient
attendances in children under 5
Accounts for 50% of admissions in under 5 in
Uganda
In MRRH malaria accounts for about 60% of
paediatric admissions
Mortality
Especially in children, malaria is a rapidly progressive and
frequently fatal illness.
Case fatality rate for severe malaria is 10-25%
Majority of the deaths occur within 1-2 days of the onset of
symptoms
Although there may be background co-morbidity, malaria
frequently kills previously healthy children
Mortality
Malaria is the main killer of children in Uganda
Or 70,000-110,000 child deaths per year
In MRRH malaria was the recorded diagnosis in 57.6% of
deaths registered over the 12-month period March 2006 – Feb
2007
Mortality
Malaria also contributes to infant mortality
through its impact on birth weight: low birth
weight (LBW) is a major factor in infant mortality
In hyperendemic areas, maternal malaria is the
main cause of low birth weight
The excess risk of LBW among PGs over that in
MGs is directly proportional to the level of malaria
transmission in the area.
Other impact
Malaria is also an important cause of chronic morbidity
Recurrent – chronic anaemia
Associated with growth restriction (stunting)
Associated with retardation of cognitive development in
children
Numerous neurological sequelae following cerebral malaria
Clinical presentation
Age:
Congenital malaria extremely rare
Clinical malaria generally rare below 2 months
Highest incidence is 3 months to 5 years
2 broad categories: uncomplicated and
complicated malaria
Clinical recognition
Early childhood is the period of highest incidence of infections
generally. Fever can be due to a wide range of infections
Most infections present with non-specific features, in a way
that is difficult to distinguish from malaria
In young children (asymptomatic) malaria parasitaemia
prevalence can be as high as 50-80%, and 20-50% in older
children.
Common symptoms
Fever:
Typically acute onset, short history
Variable, can be moderate or high grade
Classical patterns of tertian or quartan variation
unusual in children
Often have clear fever-free periods
Shivering/rigors also unusual especially in infants
May be associated with febrile seizures
Common symptoms and signs
Symptoms generally non-specific
Vomiting
Reduced appetite
Cough
Diarrhoea
Often a degree of pallor (anaemia)
Frequently enlarged spleen and liver
Other symptoms/signs reflect the emergence of
various complications
Important complications
Cerebral malaria
Seizures; due to various factors
Anaemia (haemolytic)
Metabolic acidosis
Hypoglycaemia
Pulmonary oedema
