The estimated magnitude of AIDS in Brazil: a delay correction applied to cases with lost dates

Abstract

The number of HIV-infected people is an important measure of the magnitude of the AIDS epidemic in Brazil and allows for comparison with epidemic patterns in other countries. This quantity can be estimated from the number of reported AIDS cases, which in turn needs

Reconstructing the AIDS epidemic among injection drug users in Brazil

“…Work published in Brazil has sought to address report delay and suggest ways to correct it 34 , and we have minimized this bias in our analyses by deliberately excluding the last four years of data. However, to the best of our knowledge no published paper has addressed differential under-reporting which is likely to result from the variable reliability of local and regional health information systems.…”

Is human immunodeficiency virus/acquired immunodeficiency syndrome decreasing among Brazilian injection drug users? Recent findings and how to interpret them

“…Data were compiled using SAS v8.2, creating a data archive for all Brazilian states, 1984. Data for 2001 were excluded due to reporting delays (Barbosa & Struchiner 2002). Findings reported here refer to data, registered by place of residence, for individuals aged 15-54.…”

“…Reported AIDS cases, especially in the Brazilian context of universal access to anti-retroviral therapy (where case report should be a precondition of enrollment in lifesaving treatment at no cost at the point of delivery), represent essential information to the long-term assessment of epidemic trends, if one takes into account the long incubation period and reporting delays (Barbosa & Struchiner 2002).…”

Distribuição social da AIDS no Brasil, segundo participação no mercado de trabalho, ocupação e status sócio-econômico dos casos de 1987 a 1998

“…Foram incluídos todos os casos de 20 a 49 anos de idade, correspondendo aos adultos em idade produtiva, com data de diagnóstico entre 1987 e 1998 e notificados até 30 de junho de 2001, sendo o ano de 1998 o último ano considerado, de modo a minimizar o viés decorrente do atraso da notificação (Barbosa & Struchiner, 2002).…”
