Over a period of two decades, under-5 mortality rate in Bangladesh has declined by 66% from 133 per 1000 live births in 1993-94 to 45 per 1000 live births in 2017-18. The country reached the MDG-4 goal in the reduction of child mortality on time. However, the comparison of neonatal and under-5 mortality rates in Bangladesh over the same years reveals that the reduction in the neonatal mortality rate was much slower than the child mortality rate. This led to a rise in the proportion of neonatal deaths in overall under-five deaths from 40% in 1993-1994 to 67% percent in 2017-2018. More than 75% of neonatal deaths occur within the first 7 days. To achieve SDG target 3.2, Bangladesh has to further reduce under-5 mortality rate by 44% and newborn deaths by 60%. Infection is the leading cause of preventable deaths among the neonates and the young infants and the standard recommendations for treating severe bacterial infections in infants under 2 months of age include hospitalization and 7-10 days of parenteral therapy.
