Résumé

The aim of this study was to examine the effects of age, time period, and birth cohorts with dengue fever/dengue hemorrhagic fever (DF/DHF) in Bangkok, Thailand over the period 1981-2000. The age group at greatest risk for DF/DHF was 5-9 years old. The period effect shows a remittent pattern, with significant increases in 1986-1990 and 1996-2000. The birth cohort group showed a significant decreasing trend from the 1961-1965 group to the 1991-1995 group (R2 = 0.7620) with a decreasing rate of 0.1. We concluded that the temporal trend of DF/DHF is decreasing; especially for DHF.

Résumé

HIV-1 prevalence was studied in 1,890 metamphetamine users from Thanyarak Hospital from 1999 to 2000. 64.8 per cent positive urine metamphetamine and 2.3 per cent positive urine opiate were observed. The most common route of the drug intake was 93.92 per cent inhalation. HIV-1 prevalence was 2.44 per cent (95% Confidence interval; 1.65-3.18%). 44 out of 46 HIV-1 infected cases were typeable as 32 (72.73%) subtype E and the rest of subtype B'. Active opiate users had a higher rate of HIV-1 infection, 15.91 per cent, compared to 2.11 per cent of the non-opiate users (Fisher's exact test p=0.0002). This group of metamphetamine users is important to public health and more attention on intervention efforts towards HIV infection is urgently needed.
