Integrated Management of Neonatal and Childhood Illness

Direct answer
Integrated management of neonatal and childhood illness, known as IMNCI, is a WHO and UNICEF strategy that classifies sick children with colour-coded signs. Both the young infant up to two months and the child aged 2 months to 5 years use the same pink, yellow and green scheme. Danger signs such as inability to feed, convulsions and lethargy call for urgent action before any other assessment.
What you must remember
- Age bands: the young infant covers birth to 2 months, and the sick child covers 2 months to 5 years.
- Young infant colours: pink for urgent referral (for example possible serious bacterial infection), yellow for treatment and green for home care.
- Child colours: pink for urgent referral, yellow for treatment and green for home care.
- Young infant danger signs: not feeding well, convulsions, fast breathing, severe chest indrawing, fever or hypothermia, and lethargy.
- Fast breathing thresholds: 60 or more breaths per minute under 2 months, 50 or more at 2 to 12 months, and 40 or more at 12 months to 5 years.
- Child danger signs: inability to drink or breastfeed, vomiting everything, convulsions, and lethargy or unconsciousness.
- Caregiver role: counselling and a follow-up visit are core parts of the strategy, because it relies on families to act.
Assessing a sick child step by step
IMNCI is a set of linked decisions rather than a single test, and the order matters because danger signs override every other finding. The steps below follow the sequence a first-level health worker is taught.
- Check danger signs first: ask whether the child can drink or feed, is vomiting everything, has had convulsions or is lethargic, since any danger sign makes the child urgent.
- Assess the main symptoms: check cough and breathing, diarrhoea, fever, ear problems and nutritional status, using the classification boxes for each problem.
- Count the breaths: count for a full minute when the child is calm, and apply the age thresholds of 60, 50 and 40 breaths per minute.
- Classify by colour: assign pink for severe disease needing urgent referral, yellow for disease needing treatment, and green for home care.
- Identify the treatment: choose the treatment from the chart, such as oral amoxicillin for yellow pneumonia, or oral rehydration salts and zinc for diarrhoea.
- Counsel and follow up: teach the caregiver how to give treatment and which signs mean an immediate return, then arrange a follow-up visit.
Counselling is the step most often rushed, yet it decides whether the treatment is completed at home.
Where the exam tries to catch you
IMNCI questions test the age thresholds and the urgency of colour codes. Each trap below mixes an age band or a threshold with the wrong category.
- Trap: taking 40 breaths per minute as the fast-breathing threshold for a 6-month-old. Correct: the threshold at 2 to 12 months is 50 breaths per minute, and 40 applies from 12 months to 5 years.
- Trap: treating a 3-week-old with fever at home with paracetamol. Correct: fever in a young infant is a danger sign, so the infant needs urgent referral rather than home care.
- Trap: classifying diarrhoea with some dehydration as green. Correct: some dehydration falls in the yellow category and needs treatment with oral rehydration salts in the health facility.
Frequently asked questions
What age range does IMNCI cover?
IMNCI covers two groups: the young infant from birth to 2 months, and the sick child from 2 months to 5 years. Each group has its own colour-coded classification chart. The strategy is designed for first-level health workers in primary care.
What do the colour codes mean in IMNCI?
Colour codes show the urgency of care, and the same scheme applies to young infants and to children aged 2 months to 5 years. Pink means urgent referral or admission, yellow means treatment and green means home care.
What are the fast breathing thresholds in IMNCI?
Fast breathing is defined as 60 or more breaths per minute in infants under 2 months, 50 or more in infants aged 2 to 12 months, and 40 or more in children aged 12 months to 5 years. Breaths should be counted for a full minute when the child is calm. Fast breathing with other signs suggests pneumonia.
What are the danger signs in a sick child under IMNCI?
Danger signs in a sick child include inability to drink or breastfeed, vomiting everything, convulsions, and lethargy or unconsciousness. Any danger sign means the child must be assessed urgently and may need referral. In young infants, fever, hypothermia and poor feeding are also danger signs.
Why does IMNCI include caregiver counselling and follow-up?
Counselling teaches caregivers how to give treatment at home and which danger signs require an immediate return. Follow-up checks recovery and detects problems early. Because IMNCI relies on the family to act, counselling is a core component of the strategy.
