FACTORS INFLUENCING DISEASE SEVERITY
- Most dengue virus infections produce mild, nonspecific symptoms or classic dengue fever (DF).
- Severe dengue, dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS), occurs in less than 1 percent of all dengue virus infections.
- Severe dengue risk is highest with dengue-2 viruses
- 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
- Risk of severe disease (DHF and DSS) is significantly higher during a secondary dengue virus infection than during a primary infection
- The risk for DHF appears to decline with age, especially after age 11 years.
- A specific population at higher risk for DHF in endemic areas is infants, particularly those between 6 and 12 months of age.
- DHF and DSS are less common in malnourished children than in well-nourished children
