FACTORS INFLUENCING DISEASE SEVERITY

1. Most dengue virus infections produce mild, nonspecific symptoms or classic dengue fever (DF).
2.  Severe dengue, dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS), occurs in less than 1 percent of all dengue virus infections.
3.  Severe dengue risk is highest with dengue-2 viruses
4. Genetic analyses of dengue virus isolates from the Western hemisphere strongly suggest that DHF only occurs during infection with viruses that fall into specific genotypes within each dengue serotype
5.  Risk of severe disease (DHF and DSS) is significantly higher during a secondary dengue virus infection than during a primary infection
6.  The risk for DHF appears to decline with age, especially after age 11 years.
7.  A specific population at higher risk for DHF in endemic areas is infants, particularly those between 6 and 12 months of age.
8.  DHF and DSS are less common in malnourished children than in well-nourished children
