Gastroenteritis
In 2015, the world witnessed two billion cases of gastroenteritis. This massive number resulted in 1.3 million deaths globally that same year. The disease strikes hardest against children and populations living in developing nations. In those younger than five years old, about 1.7 billion cases occurred by 2011 alone. These figures represent a staggering human cost hidden behind common symptoms like diarrhea and vomiting.
Contaminated water sources drive transmission rates during rainy seasons when quality worsens significantly. Outbreaks become more common in winter months within areas experiencing four distinct seasons. Bottle-feeding babies with improperly sanitized bottles creates a significant cause of infection worldwide. Poor hygiene practices among children increase risk levels inside crowded households. Adults who have developed immunities may still carry certain organisms without showing symptoms.
The World Health Organization recommended rotavirus vaccine availability for all children globally starting in 2009. Implementation of vaccination programs in the United States decreased diarrhea cases by as much as 80 percent since 2000. Hand washing with soap decreases rates of gastroenteritis by up to 30 percent in both developing and developed worlds. Breast milk reduces both frequency and duration of infections especially where hygiene is poor. Oral cholera vaccines show effectiveness between 50 and 60 percent over two years.
Gastroenteritis caused 4.6 million deaths in children in 1980 before dropping to approximately 1.5 million annually by 2000. Cholera causes about three to five million cases yearly while killing approximately 100,000 people. More than 450,000 fatalities are due specifically to rotavirus in children under five years old. In the US alone, these infections result in between 200 and 375 million cases of acute diarrhea annually. About ten thousand deaths occur each year within that same country.
Oral rehydration therapy serves as the preferred treatment for mild to moderate dehydration cases worldwide. Drinking replacement products made from complex carbohydrates like wheat or rice may be superior to simple sugar based drinks. Soft drinks and fruit juices increase diarrhea risk in children under five years of age. The BRAT diet containing bananas and toast no longer receives recommendation due to insufficient nutrients. Zinc supplementation appears effective in both treating and preventing diarrhea among developing world children.
