New Delhi,Pneumonia kills more children than any other infectious disease, claiming the lives of over 800,000 children under five every year, or around 2,200 every day. This includes over 153,000 newborns. Comparatively in 2018, 437,000 children under five died due to diarrhea and 272,000 to malaria. Globally, there are over 1,400 cases of pneumonia per 100,000 children, or 1 case per 71 children every year, with the greatest incidence occurring in South Asia (2,500 cases per 100,000 children) and West and Central Africa (1,620 cases per 100,000 children).
Progress in reducing deaths due to pneumonia in children under five has been significantly slower than for other infectious diseases. Since 2000, under-five deaths due to pneumonia have declined by 54 per cent, while deaths due to diarrhoea have decreased by 64 per cent and are now almost half of pneumonia deaths.
Mortality due to childhood pneumonia is strongly linked to poverty-related factors such as under nutrition, lack of safe drinking water and sanitation, indoor air pollution and inadequate access to health care. An estimated 18 million more health workers are needed by 2030 to prevent, diagnose and treat pneumonia as well as to reach the SDG targets on universal health coverage. Currently, 32 per cent of children with suspected pneumonia are not taken to a health facility worldwide, while that number rises to 40 per cent for the poorest children in low- and middle-income countries.
Around half of childhood pneumonia deaths are associated with air pollution. The effects of indoor air pollution kill more children globally than outdoor air pollution. At the same time, around two billion children 0-17 years of age live in areas where outdoor air pollution exceeds international guideline limits.
Simple solutions can save children’s lives
The Integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhea (GAPPD) sets forth an integrated framework of key interventions proven to effectively protect children’s health, prevent disease and appropriately treat children who do fall ill with diarrhea and pneumonia.
Protect: Protective interventions provide the foundations for keeping children healthy and free of disease
Exclusive breastfeeding for the first 6 months of life (without additional foods or liquids, including water) protects infants from disease and guarantees them a food source that is safe, clean, accessible and perfectly tailored to their needs. Nearly half of all diarrhea episodes and one-third of all respiratory infections could be prevented with increased breastfeeding in low- and middle-income countries.
Adequate complementary feeding and continued breastfeeding: good nutrition supports strong immune systems and provides protection from disease. From 6 months to 2 years of age, adequate complementary feeding – providing children with adequate quantities of safe, nutritious and age-appropriate foods alongside continued breastfeeding – can reduce child deaths, including those due to pneumonia and diarrhoea.
Vitamin A supplementation: High-dose vitamin A supplementation helps maintain strong immune systems and can reduce all-cause mortality by 24 per cent and cases of diarrhea by 15 per cent. Children between the ages of 6-59 months should be protected with 2 high-dose supplements of vitamin A every year in countries with high under-five mortality or where vitamin A deficiency is a public health problem.
Prevent: Preventative interventions help stop disease transmission and prevent children from becoming ill
Immunization: The Haemophilus influenzae type b (Hib) and pneumococcal conjugate vaccines (PCV) are effective in preventing the two most common bacterial causes of childhood pneumonia and the rotavirus vaccine provides protection against one of the most common causes of childhood diarrhoea-related death. The use of vaccines against measles and pertussis in national immunization programmes substantially reduces pneumonia illness and death in children. In 2018, 71 million children did not receive the recommended three doses of PCV, putting them at higher risk of pneumonia.
Safe drinking water, sanitation and hygiene: Almost 60 per cent of deaths due to diarrhoea worldwide are attributable to unsafe drinking water and poor hygiene and sanitation. Hand washing with soap alone can cut the risk of diarrhoea by at least 40 per cent and significantly lower the risk of respiratory infections. Clean home environments and good hygiene are important for preventing the spread of both pneumonia and diarrhoea. Safe drinking water and proper disposal of human waste, including child faeces, are vital to stopping the spread of diarrhoeal disease among children and adults.
Reduced household air pollution: More than 40 per cent of the world’s population rely on solid fuels (wood, coal, animal dung and crop waste) to cook and heat their homes, exposing children to household air pollution and almost doubling their risk of pneumonia. Improved household air quality can reduce cases of severe pneumonia while also preventing burns, saving time and reducing fuel costs. The use of chimney stoves can cut household air pollution by half, reducing severe pneumonia by almost 30 per cent.
HIV prevention: Preventing HIV and treating HIV infections with antiretroviral drugs helps maintain the immune system and reduce the risk of contracting pneumonia. Co-trimoxazole prophylaxis provides further pneumonia-related protection for HIV-infected and exposed children and can reduce AIDS deaths by 33 per cent.
Diagnose and Treat: Treatment interventions – when timely and appropriate – can cure children from pneumonia and ensure survival
Saving children from pneumonia requires urgent action and recognizing danger signs – including fast and difficult breathing and a cough – is the first step. The treatment for most types of serious pneumonia is often antibiotics, which typically cost less than 50 cents for a full treatment. However, not all children with symptoms of pneumonia should receive antibiotics: According to the WHO and UNICEF Integrated Management of Childhood Illness guidelines, only those cases classified by a health worker as pneumonia should be treated with antibiotics. Moreover, not all children classified as such have true pneumonia. That said, in settings without adequate diagnostic tools, the WHO/UNICEF guidelines provide a common standard by which health workers can assess and classify bacterial pneumonia illnesses requiring antibiotic treatment.
Globally, 68% of children with pneumonia symptoms are taken to a health care provider. Although it cannot be assumed that all children with symptoms have bacterial pneumonia and should receive antibiotics, the data indicate a big gap between the rich and the poor in treatment of symptoms of pneumonia, with only 60 per cent of children in poor households versus 79 per cent of children in rich households receiving care for pneumonia symptoms from a healthcare provider.
Taking children to a health care provider quickly can save their lives, yet, worldwide, only about two-thirds of children receive the necessary help and care when pneumonia symptoms arise. In sub-Saharan Africa, where most pneumonia deaths occur, only 57 per cent of children with pneumonia symptoms are taken for care. As data from population-based survey data indicate, there has not been major progress in careseeking behavior for pneumonia symptoms since 2000.
