title: [Clinical differences observed in patients with dengue caused by different serotypes in the epidemic of 2001/2002, occurred in Rio de Janeiro].
abstract: The authors evaluated clinical and epidemiological differences among the serotypes of dengue in Rio de Janeiro's 2001-2002 outbreak of the disease. Out of 362 cases that had viral isolation samples, notified by the Information System for Notification Diseases (SINAN), from January/2001 to June/2002, 62 were caused by serotype 1,62 by serotype 2 and 238 by serotype 3. In comparison with serotype 2, an individual infected by serotype 3 had a 6.07 times higher chance (OR = 6.07; CI: 1.10-43.97) of presenting shock and a 3.55 times higher chance (OR = 3.55; CI: 1.28-9.97) of developing exanthema. When compared to serotype 1, serotype 3 had a 3.06 times higher chance (OR = 3.06; CI: 0.99-9.66) of causing abdominal pain and a 3.61 times higher chance of exanthema (OR = 3.61; CI: 1.16-11.51). It was found that individuals infected by serotype 3 of the virus presented signs indicating a more severe disease.
