“…No Brasil, períodos de silêncio são comumente citados na literatura, associando-os a ciclos periódicos. Um levantamento de dados sobre a tendência da peste no Ceará, entre 1935 e 2004, caracterizou a ocorrência de casos humanos pela alternância de momentos com elevadas incidências e períodos de silêncio, sendo o último caso registrado em 2005 e o anterior em 1997 6 .…”

“…No Brasil, a peste chegou pelo porto de Santos em 1899 atingindo, em seguida, várias cidades do litoral 5 . Dados registrados desde 1935 revelam que o período de maior intensidade na ocorrência da doença antecede a década de 70, entrando em declínio logo após, verificando epidemias isoladas nos anos 1970, na Bahia, e 1980, nos Estados do Ceará e Paraíba 6,7 . A década seguinte é caracterizada pelo registro de casos esporádicos, concentrados na Bahia, sendo os últimos registrados, neste estado, no MÉTODOS município de Feira de Santana, em 2000.…”

“…Since 1990, human plague cases have been rare and sporadic. In the State of Ceará, Northeastern Brazil, the last laboratory-confirmed human cases occurred in the 1990s, with the exception of one case in 2005, which was initially misdiagnosed as dengue 7 .…”

Introduction:In Brazil, the plague is established in several foci located mainly in the northeastern part of the country, where it alternates between active and quiescent periods. These foci in the State of Ceará have high epidemiological importance. In addition to other plague detection activities, plague areas can be monitored through serological surveys of dogs and cats (domestic carnivores), which, following feeding on plague-infected rodents, can develop mild to severe forms of the disease and produce long-lasting antibodies. This study aimed to characterize the circulation dynamics and spatial distribution of Yersinia pestis antibodies in dogs and cats in plague foci areas of Ceará. Methods: An ecological study was conducted to analyze the temporal series and spatial distribution of secondary data obtained from domestic carnivore serum surveillance in Ceará's plague areas from 1990 to 2014. Results: Joinpoint analysis revealed that the overall trend was a reduction in antibody-positive animals. The mean proportion of antibody-positivity during the whole study period was 1.5% (3,023/203,311) for dogs, and 0.7% (426/61,135) for cats, with more than 4% antibody-positivity in dogs in 1997 and 2002. Antibody titers ranging from 1/16 to 1/64 were frequent. Despite fluctuations and a significant reduction, in recent years, there were antibody-positive animals annually throughout the study period, and the localities containing antibody-positive animals increased in number. Conclusion: Yersinia pestis is actively circulating in the study areas, posing a danger to the human population.

Plague is a disease of epidemic potential that may emerge with discontinuous outbreaks. In South America, 50 wild rodent species have been identified as plague reservoirs, in addition to one lagomorph and two marsupials. To review the nomenclature of plague reservoirs, we examined specimens collected in plague foci, carried out new surveys in Brazilian plague regions, and re-evaluated the nomenclature of South American reservoirs on the basis of the current literature. Five of the 15 species involved with plague in Argentina, three of 10 species involved with plague in Bolivia, three of the seven species involved with plague in Peru, five of the nine species involved with plague in Ecuador, and six of the nine species involved with plague in Brazil have undergone taxonomic changes. In the last 20 years, plague cases were recorded in Bolivia, Brazil, Ecuador, and Peru. These four countries have a high rodent species richness in plague foci, a fact that may be decisive for the maintenance of plague in the wild.
