Death Rate: Calculated by dividing the number of deaths in a population in a year by the midyear resident population. Death rates are expressed as the number of deaths per 100,000 populations. The rate may be restricted to deaths in a specific age range, race, sex or geographic groups or from specific causes of death.
Diagnosis: A judgment about what particular illness or problem is present; made after an examination.
Diphtheria: An acute infectious disease that typically strikes the upper respiratory tract including the throat.
DNA: Deoxyribonucleic acid; the chemical at the center of cells of living things that controls the structure and purpose of each cell and carries the genetic information during reproduction.
DTaP Vaccines: A vaccine for Diptheria, Tetanus and Pertussis.
Ectopic Pregnancy: A pregnancy that is not in the uterus. The fertilized egg settles and grows in any location other than the inner lining of the uterus. The large majority (95 percent) of ectopic pregnancies occur in the fallopian tube. However, they can occur in other locations, such as the ovary, cervix and abdominal cavity. An ectopic pregnancy occurs in about 1 in 60 pregnancies.
Epidemiology: The study of the distribution and causes of disease in populations. Tracking the number of cases of disease by person, place and time allows public health authorities to better identify who is at risk, trends of occurrence and strategies for disease prevention and control.
Erythematous: Name applied to redness of the skin produced by congestion of the capillaries, which may result from a variety of causes.
Etiology: The scientific study of the causes of diseases. Currently, the etiology or cause of SIDS remains unknown. However, research has revealed many things about SIDS and what SIDS is not.
Evidence-Based: Proven to be effective through scientific study.
Fetal Alcohol Syndrome (FAS): The sum total of the damage done to the child before birth as a result of the mother drinking alcohol during pregnancy. Fetal alcohol syndrome always involves brain damage, impaired growth and head and face abnormalities.
Fetal Death Rate: The number of fetal deaths with stated or presumed gestation of 20 weeks or later or if they weigh 350 grams or more divided by the sum of live births plus fetal deaths, stated per 1,000 live births plus fetal deaths.
Note: States are required to report fetal deaths in the 20th week or later of gestation or if they weigh at least 350 grams. Numbers of fetal deaths may be underreported because of variations in reporting requirements by States.
Fertility Rate: The total number of live births, regardless of age of mother, per 1,000 women of reproductive age (15 to 44 years of age).
