Mortalidade por esquistossomose no Brasil, 1977-1986

Abstract

Os autores apresentam dados de mortalidade por esquistossomose no país, macrorregiões e unidades federadas, no período de 1977-1986, e relacionam os coeficientes de mortalidade com o programa de controle. O impacto se demonstra evidente, especialmente em função da população para a qual o risco de reinfecção foi reduzido ou eliminado. São apresentados também dados relativos a mortalidade proporcional e distribuição por idade.

An analysis of the impact of the Schistosomiasis Control Programme in Brazil

“…For this reason, reducing the gravity and mortality has become the number one objective to be achieved by the control programmes (Silveira et al 1990).…”

“…In this case, because of the possibility of underestimating the indicator, due, especially, to factors related to death notification services. It also has to be mentioned that, the growth curve in the mortality and hospitalization rates seen in the first few years of introduction of the SIM and SIH has been attributed to the gradual inclusion of new notification units, and not to the disease's trend (Silveira et al 1990, Carmo 1999. In this paper, it was noticed that there was a continuity in the downward trend of mortality for schistosomiasis in the country already indicated in the paper by Silveira et al (1990).…”

In this paper, it was noticed that there was a continuity in the downward trend of mortality for schistosomiasis in the country already indicated in the paper by Silveira et al (1990). These authors also pointed out, in the analysis of 7385 deaths, the rare nature of the incidence in the under-20 age group and predominance in the over 40 age group.…”

The influence of the age-period-cohort effects on the temporal trend mortality from schistosomiasis in Brazil from 1980 to 2014

“…In Brazil, the actions of the Epidemiological Surveillance of Schistosomiasis carried out by the Ministry of Health allow the diagnosis and treatment of patients with S. mansoni, in order to: a) reduce the occurrence of severe forms and, consequently, of deaths; b) reduce the prevalence of infection; c) indicate measures to reduce the risk of disease spread [6]. Since the introduction of new drugs administered in a single dose and their use on a large scale, a significant reduction in the number of cases that developed severe forms of schistosomiasis has been observed [7]. Nowadays, the lethality is considered low.…”

“…However, even with such measures, between 2006 and 2015 there were about 508 deaths per year in the country [1,2]. So, surveillance of the magnitude and dynamics of transmission, severe forms and deaths related to schistosomiasis in Brazil are essential to monitor and evaluate the effectiveness of disease control measures [7][8][9][10].…”
