What are the key health dangers for children?
Q: What are the key health dangers for children, and what is WHO doing to address them?
A: Nearly 10 million children under the age of five die each year – more than 1000 every hour – but most could survive threats and thrive with access to simple, affordable interventions.
The risk of death is highest in the first month of life. Preterm birth, birth asphyxia and infections cause most newborn deaths. Health risks to newborns are minimized by:
- quality care during pregnancy;
- safe delivery by a skilled birth attendant; and
- strong neonatal care: immediate attention to breathing and warmth, hygienic cord and skin care, and early initiation of exclusive breastfeeding.
From one month to five years of age, the main causes of death are pneumonia, diarrhoea, malaria, measles and HIV. Malnutrition is estimated to contribute to more than one third of all child deaths.
- Pneumonia is the prime cause of death in children under five years of age. Nearly three-quarters of all cases occur in just 15 countries. Addressing the major risk factors – including malnutrition and indoor air pollution – is essential to preventing pneumonia, as are vaccination and breastfeeding. Antibiotics and oxygen are vital tools for effectively managing the illness.
- Diarrhoeal diseases are a leading cause of sickness and death among children in developing countries. Breastfeeding helps prevent diarrhoea among young children. Treatment for sick children with Oral Rehydration Salts (ORS) combined with zinc supplements is safe, cost-effective, and saves lives.
- One African child dies every 30 seconds from malaria. Insecticide-treated nets prevent transmission and increase child survival.
- Over 90% of children with HIV are infected through mother-to-child transmission, which can be prevented with antiretrovirals, as well as safer delivery and feeding practices.
- About 20 million children under five worldwide are severely malnourished, which leaves them more vulnerable to illness and early death.
About two-thirds of child deaths are preventable through practical, low-cost interventions. WHO is improving child health by helping countries to deliver integrated, effective care in a continuum - starting with a healthy pregnancy for the mother, through birth and care up to five years of age. Investing in strong health systems is key to prevention and delivery of quality care.
