* can be a serious disease in very young children if treated inappropriately
  - particularly severe in young children
  - severe, especially in babies younger than a year old
  - have serious complications, such as pneumonia, brain dysfunction and seizure
  - lead to pneumonia and seizures
  - occur in adults as well as children
* has a characteristic cough, which gives it the name
  - three stages
* highly communicable disease of the respiratory tract
  - contagious bacterial infection
* is also highly contagious and can cause violent coughing
  - very rare now thanks to vaccination
  - an infectious disease
  - caused by bacteria that attach to the cells in the airway
  - more prevalent among adults than reported statistics reveal
  - most dangerous to infants
  - no longer common because most children get shots to prevent it
  - primarily a disease of infants and preschool children
  - rare for a reason, and regular vaccines can keep it that way
  - transmitted through the air when an infected person coughs
* mild condition in otherwise healthy children and leaves no permanent damage.
* occurs on an infrequent basis as most children are vaccinated early in childhood.
* remains an important cause of respiratory illness in all age groups.

Yellow fever
* are diseases
  - viral infection.
  * is spread through the bite of an infected mosquito. It does not spread from person to person by direct contact
* begins suddenly after an incubation period of three to five days.
* can affect both sexes, all ages and races
  - kill within four to eight days of the onset of the disease
  - lead to delirium, coma, and death
* damages the liver causing the skin to turn yellowish.
* exists in Africa in a cycle involving small mammals and fowl.
* febrile hemorrhagic disease characterized by hepatic and renal failure.
* is an acute mosquito-born viral infection
  - apparently difficult to diagnose without modern diagnostic aids
  - carried by mosquitoes in warm climates, so it is eliminated as a cause
  - caused by ticks and mosquitoes
  - contracted when the virus is transmitted by mosquito bites
  - difficult to recognize, especially during the early stages
* is endemic in tropical Africa and America
  - is large portions of Brazil
  - epidemic in the West Indies
  - eradicated in Panama
* is found in jungle areas, especially in South America
  - some African and Latin American countries
  - located only in Africa and South America
* is transmitted by mosquitoes
  - the bite of infected mosquitoes
* kills a traveler.
* mosquito-born disease.
* mosquito-borne viral disease
* occurs in tropical areas only in certain regions of South America and Africa.
* presents with the abrupt onset of fever and chills.
* reappears in Brazil after nearly a year s absence.
* serious viral infection , transmitted by mosquitoes in tropical regions.
* viral disease found in parts of Africa and South America
  - spread in humans by mosquito vectors
* viral disease that has caused large epidemics in Africa and the Americas
  - transmitted between humans by a mosquito
  - illness spread by mosquitoes in parts of Africa and South America

Complex disease
* Most complex diseases associate with deficiencies
  - magnesium deficiencies
* comprise the major contributors to morbidity and mortality in developed countries.

Corneal disease
* can also be a contributing factor.
* is characterized by blurred vision or blindness stemming from damage to the cornea
  - the second leading cause of visual loss worldwide
