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.
“…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 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].…”
Background Schistosomiasis is highly debilitating and related to poverty, leading to chronic health problems. This disease is important for public health due to the high prevalence, severity of clinical forms and heterogeneous spatial and temporal patterns. In Brazil, about 1.5 million people are at risk of infection with Schistosoma mansoni, with an annual average of 500 deaths. In this study, the temporal change in mortality was evaluated in relation to the effects of age, period and birth cohort, in Brazil and regions, from 1980 to 2014. Methods In this study, we analyzed the influence of age, period and birth cohort (APC effects) on the temporal evolution of schistosomiasis mortality in Brazil from 1980 to 2014, according to sex and geographic regions of the country. The death records were extracted from the SIM (Mortality Information System) of the DATASUS website (Department of National Health Informatics) of the Ministry of Health of Brazil. The temporal effects were estimated using Bayesian models and the INLA (Integrated Nested Laplace Approximations) method for parameter inference. Results More than 24 thousand deaths were registered in the analyzed period, mainly in men from the Northeast region. In Brazil, children under 14 years of age had protection against death from schistosomiasis. There was no significant effect for others ages. From 1990 to 1999, there was a protective effect for death from schistosomiasis and a null effect in the other periods. There was a decreasing trend in the risk of death among birth cohorts. The greatest risk was among people born from 1903 to 1912. There was a protective effect for death among people born after 1968. Men were at risk of death between 25 and 54 years old, while women were at risk after seventy years of age. The southern and central-western regions had a risk of death until 1989 and had a protective effect between1995 and 1999.
