10 Questions

What is the difference between contagious and communicable diseases?

Contagious diseases are transmitted through direct contact, while communicable diseases arise through transmission from an infected person to a susceptible host

What is the definition of infection?

Entry and development of an infectious agent in the body

What defines an epidemic?

The unusual occurrence of cases of an illness clearly in excess of expected occurrence in a community or region

What does endemic refer to?

The constant presence of a disease within a given geographical area

What is contamination defined as?

Presence of an infectious agent on a body surface or substances

What is the main cause of anemia in individuals with sideroblastic anemia (SA)?

Lack of red blood cells and excess iron due to inefficient iron utilization

What are the potential medical complications for adults with acquired sideroblastic anemia?

Heart disease and cirrhosis

How do infants and young children born with sideroblastic anemia differ from adults who develop the condition?

They may have life-threatening medical issues stemming from iron overload

What can healthcare providers do for individuals with congenital sideroblastic anemia (CSA)?

Manage symptoms and prevent serious medical complications with medications

How do people typically acquire sideroblastic anemia?

Related blood disorders, certain medications, or excessive exposure to certain minerals

Study Notes

Disease Terms

  • Contagious diseases are capable of being transmitted from person to person, while communicable diseases are those that can be transmitted from person to person, animal to person, or via vectors (e.g., insects).
  • Infection is defined as the invasion and multiplication of microorganisms in the body, resulting in a host response.

Epidemiology

  • An epidemic is the rapid spread of a disease in a specific geographic area, exceeding what is expected.
  • Endemic refers to a disease or condition that is consistently present and prevalent in a particular population or region.

Sideroblastic Anemia

  • The main cause of anemia in individuals with sideroblastic anemia (SA) is a defect in the production of heme, a critical component of hemoglobin.
  • Potential medical complications for adults with acquired sideroblastic anemia include cardiovascular disease, liver disease, and increased risk of cancer.
  • Infants and young children born with sideroblastic anemia differ from adults who develop the condition in that they typically present with more severe anemia, failure to thrive, and developmental delays.
  • Healthcare providers can help individuals with congenital sideroblastic anemia (CSA) by providing blood transfusions, folic acid supplementation, and bone marrow transplantation.
  • Sideroblastic anemia can be acquired through exposure to toxins, such as lead or copper, or inherited in an autosomal recessive pattern.
  • Congenital sideroblastic anemia is often inherited from birth, resulting from mutations in genes involved in heme biosynthesis.
