What is the disproportionate burden of preventable illnesses and deaths in lower-income countries
primarily caused by?
Diarrheal diseases and pneumonia.
What types of infections pose a risk to everyone, regardless of income level?
Foodborne infections, influenza, coronavirus, viral hepatitis, and other infectious diseases.
Why is global cooperation critical in the context of infectious diseases?
To contain emerging infectious diseases with pandemic potential and ensure every child receives
recommended vaccines.
What are the primary causes of millions of deaths each year related to infectious diseases?
Bacteria, viruses, and parasites.
What proportion of deaths from infectious diseases in a typical year are among infants, children, or
adolescents?
About 1 in 3.
In which income-level countries do most deaths from infections in children occur?
Low- or lower-middle-income countries.
What inexpensive interventions could prevent the vast majority of fatal childhood infections?
Childhood vaccinations, reliable access to clean drinking water, and bednets to block mosquito bites.
What could have averted the majority of deaths from infectious diseases when prevention methods fail?
Antibiotics and other types of basic medical care.
Why should infectious disease prevention and control remain a global health priority?
Due to the unnecessary burden of infectious diseases on children in low-income countries.
What demographic is significantly affected by infectious diseases beyond children?
People of all ages, all socioeconomic levels, and all geographies.
What is essential for stopping a pandemic according to the notes?
International cooperation.
What is the main focus of Chapter 9 in the context of global health?
The impact of infectious diseases on children and the need for prevention and control measures.
, What is an enteric infection?
An infection of the intestinal tract.
What is gastroenteritis?

How is diarrhea characterized?
By loose or liquid feces and an increased frequency of defecation.
What can severe diarrhea lead to?
Dehydration, which is the excessive loss of water from the body.
What are the potential consequences of extreme dehydration?
Kidney failure, heart failure, and potentially death.
How many new cases of infectious diarrheal disease occur worldwide each year?
More than 6 billion.
How many people die each year from diarrheal diseases?
An estimated 1.5 million.
Which populations are most affected by diarrheal disease fatalities?
Young children and older adults in low- or lower-middle-income countries.

Diarrhea.
What virus is the most frequent cause of severe diarrhea among infants and young children?
Rotavirus.
Which virus frequently causes severe diarrhea among adults?
Norovirus.
What bacteria causes cholera and what are its effects?
Vibrio cholerae causes severe watery diarrhea, with up to 3 million cases annually.
What is food intoxication?
Illness caused when ingested bacteria produce toxins in the body.
Name some bacteria that are frequent causes of diarrhea.
Campylobacter, Salmonella, and Shigella.
