     I found the information to write up these diseases on a very interesting
and Informative web site called 'Outbreak'.  This site has an active outbreak
listing, plus information regarding some of the deadliest disease's known to
mankind.  If it wasn't for this web page, I would not have been able to create
this dreaded nasty to be used with the disease system I wrote up for The
Morrow Project.
     If interested, the address for the web site is listed below:

Dengue Hemorrhagic Fever

     In humans, dengue infection causes a spectrum of illness ranging from
mild, nonspecific viral syndrome to severe hemorrhagic disease and death. The
severe hemorrhagic form of disease is called dengue hemorrhagic fever (DHF)
and dengue shock syndrome (DSS).

Dengue Fever
     SU-(A)-CON-2D8 Days -3-1+1D6 Days
     Puerpera, Lesions.

     DHF/DSS is characterized by a sudden onset of fever, usually of 2 to 7
days duration, and a variety of nonspecific signs and symptoms. During the
acute phase of illness, it is difficult to distinguish DHF/DSS from dengue
fever and other viral illnesses. The critical stage of DHF/DSS occurs most
frequently from 24 before to 24 hours after the temperature falls to or below
normal. During this time, hemorrhagic manifestations usually occur, and more
importantly, signs of circulatory failure may appear.  The most common
hemorrhagic manifestations are skin lesions, but epistaxis, bleeding gums,
gastrointestinal hemorrhage and hematuria can also occur.
     The incubation period for DF/DHF can be as short as 2 days and as long
as 16 days. The average incubation period is 4 to 6 days.
     Dengue viruses are transmitted in nature by day-biting mosquitoes.
     Dengue viruses are not communicable and person-to-person transmission
does not occur.
     An infected individual is never infectious to other persons, but remains
infectious for mosquitoes for an average of about 6 days.
     The best way to avoid dengue infection is to avoid mosquito bites. The
highest risk of dengue infection occurs in tropical urban areas. The mosquito
vectors of dengue are day-biters, with peak feeding activity in the morning
for several hours after daybreak and in the late afternoon for several hours
before dark. However, these mosquitoes may feed throughout the day in the
shade, indoors, or on overcast days. To avoid mosquito bites, persons should
be aware of the above feeding behavior and use repellents.
     Survival of the infection confers lifelong immunity to reinfection.
     There is no therapeutic cure or vaccine available.
