Diseases constituted 9 of all deaths among children <5 years old in 2015.4 Although the burden of diarrheal diseases is much lower in developed countries, it is an important public health problem in low- and middle-income countries because the disease is particularly dangerous for young children, who are more susceptible to dehydration and nutritional losses in those settings.5 In Bangladesh, the burden of diarrheal diseases is significant among children <5 years old.6 Global estimates of the mortality resulting from diarrhea have shown a steady decline since the 1980s. However, despite all advances in health technology, improved management, and increased use of oral rehydrationtherapy, diarrheal diseases are also still a leading cause of public health concern.7 Moreover, morbidity caused by diarrhea has not declined as rapidly as mortality, and global estimates remain at between 2 and 3 episodes of diarrhea annually for children <5 years old.8 There are several studies assessing the prevalence of childhood diarrhea in children <5 years of age. However, in Bangladesh, information on the age-specific prevalence rate of childhood diarrhea is still limited, although such studies are vital for informing policies and allowing international comparisons.9,10 Clinically speaking, diarrhea is an alteration in a normal bowel movement characterized by an increase in theInternational Centre for Diarrhoeal Disease Research, Dhaka, Bangladesh 2 University of Strathclyde, Glasgow, UK Corresponding Author: Abdur Razzaque Sarker, Health Economics and Financing Research, International Centre for Diarrhoeal Disease Research, 68, Shaheed Tajuddin Sarani, Dhaka 1212, Bangladesh.

Determined by a community-based study point of view, diarrhea is defined as no less than 3 or much more loose stools inside a 24-hour period.12 A diarrheal episode is viewed as because the passage of 3 or more loose or liquid stools in 24 hours before presentation for care, which can be regarded as one of the most practicable in children and adults.13 Having said that, prolonged and persistent diarrhea can final in between 7 and 13 days and at the very least 14 days, respectively.14,15 The disease is extremely sensitive to climate, displaying seasonal variations in many sites.16 The climate sensitivity of diarrheal disease is constant with observations of the direct effects of climate variables on the causative agents. Temperature and relative humidity have a direct influence on the price of replication of bacterial and protozoan pathogens and on the survival of enteroviruses inside the environment.17 Overall health care journal.pone.0169185 searching for is recognized to be a result of a complicated behavioral procedure which is influenced by various things, such as socioeconomic and demographic and traits, perceived require, accessibility, and service availability.
