Spatial, temporal, and space-time analysis of leptospirosis cases in Acre, 2001-2022.

Objective: To identify clusters of high and low risk for the occurrence of leptospirosis in space and space-time in Acre, between 2001 and 2022, as well as to characterize temporal trends and epidemiological profiles of the disease in the state.

Methods: An ecological study of cases mandatorily reported by health services in Brazil. For the analysis of clusters in space and space-time, the SaTScan software was used, which calculated the relative risks (RR).

Sand Fly Fauna in Urban Parks in the Brazilian Western Amazon: Potential Areas for American Cutaneous Leishmaniasis Transmission.

Sand flies are a group of insects (Diptera, Psychodidae, Phlebotominae) in which some species may transmit agents of leishmaniasis. This study aimed to analyze the sand fly fauna in urban parks in Rio Branco, capital of Acre state, addressing its diversity, infection by Leishmania, and food sources in sand fly females. The sand flies were collected with CDC-type automatic light traps installed in three urban parks in Rio Branco: Captain Ciríaco, Horto Florestal and Chico Mendes.

Preliminary observations of the urbanization and domiciliation of the American cutaneous leishmaniasis in Rio Branco, Acre, Western Amazon.

Background: The American cutaneous leishmaniasis (ACL) is expanding in peri-urban environments.

Methods: An entomological survey was conducted in the area of the occurrence of an autochthonous urban case of ACL. Sandflies and a parasitological slide of the human case were submitted for molecular diagnosis.

Intestinal parasite infections associated with sociodemographic and seasonal factors in the Western Amazon.

Intestinal parasites are a constant public health problem in the Amazon region, with a high prevalence of cases related to poor sanitary conditions. We investigated the sociodemographic and seasonal factors associated with human intestinal parasite infections in an area of the Western Amazon, Brazil, from September 2017 to August 2019. Data were collected using a database available at the Diagnostic Support Centre (Centro de Apoio ao Diagnóstico, CAD) of the Municipality of Rio Branco, on positive diagnoses for intestinal parasites.

Temporal trend and epidemiological profile of accidents involving venomous animals in Brazil, 2007-2019.

Objective: to analyze the temporal trend of accidents involving venomous animals in Brazil from 2007 to 2019.

Methods: this was a cross-sectional study carried out with data from the Notifiable Health Conditions Information System (SINAN). Prais-Winsten linear regression was used for the temporal analysis.

Phlebotomine Fauna (Diptera: Psychodidae) and Infection by Leishmania spp. in Forest Fragments of a University Campus, Western Amazon.

Forest fragments consist of important ecosystems for the maintenance of sand fly populations and Leishmania hosts. This study sought to identify the phlebotomine fauna and its infection by Leishmania spp. in forest fragments on the campus of the Federal University of Acre (UFAC), Western Amazon.

Trypanosomes of vectors and domestic dogs in Trypanosoma cruzi transmission areas from Brazilian southwestern amazon: New mammalian host for Trypanosoma janseni.

Trypanosoma cruzi is a widespread protozoan in Latin America causing Chagas disease in humans and able to infect several other mammal species. The objective of this study was to investigate the T. cruzi infection in triatomine fauna as well as in dogs from distinct areas of Acre, western Brazilian Amazonia, which recently reported acute cases of human CD as well as an area that have not notify this disease recently.

Climate variability and hospitalizations due to infectious diarrheal diseases in a municipality of the Western Brazilian Amazon Region.

Morbimortality due to infectious diarrheal diseases still is a serious health issue in Brazil and is highly related to factors such as weather, environment, and people's life conditions. This study aimed to analyze the relationship between hospitalization rates due to infectious diarrheal diseases among the population of the municipality of Rio Branco (AC), Brazil and precipitation, river level, humidity and temperature between 2000 and 2013. Data were retrieved from the Hospital Information System of the SUS (Unified Health System), the National Institute of Meteorology and the National Water Agency.

Leishmania (Viannia) braziliensis type 2 as probable etiological agent of canine cutaneous leishmaniasis in Brazilian Amazon.

Canine cutaneous leishmaniasis (CCL) is a zoonosis of public health interest, and in the Americas, Leishmania (Viannia) braziliensis has been identified as the main etiological agent. The present study sought to investigate Leishmania spp. infection in domestic dogs from a rural area of the Xapuri municipality, Acre state, Brazilian Amazonia.

Entomological Survey of the Mosquitoes in an Area of Ecological TOurism in the Brazilian Amazon Basin.

Mosquitoes have a great epidemiological importance, since females of several species transmit etiological agents of human diseases, such as malaria and arboviruses. In Brazil, the state of Acre has been highlighted in recent years for its high incidence of diseases of relevance to public health, such as malaria, dengue, and leishmaniases, whose etiological agents are transmitted by insect vectors, including mosquitoes. Nevertheless, few studies have been carried out on the mosquito fauna in Acre State; this study aims to identify the culicid fauna of an ecological tourism area of the municipality of Xapuri, Acre State, Brazilian Amazon.

Attractiveness of black and white modified Shannon traps to phlebotomine sandflies (Diptera, Psychodidae) in the Brazilian Amazon Basin, an area of intense transmission of American cutaneous leishmaniasis.

In the Amazon region the phlebotomine fauna is considered one of the most diverse in the world. The use of Shannon traps may provide information on the anthropophily of the species and improve the traps' performance in terms of diversity and quantity of insects collected when white and black colored traps are used together. This study sought to verify the attractiveness of the traps to the phlebotomine species of the Brazilian Amazon basin using Shannon traps under these conditions.

Spatial and temporal distribution of American cutaneous leishmaniasis in Acre state, Brazil.

Background: Acre has reported the highest incidence of American cutaneous leishmaniasis (ACL) in Brazil in recent years. The present study seeks to identify high and low risk agglomerations of ACL in space and space-time during the period from 2007 to 2013 in Acre, and also to characterize the occurrence of the disease in time and according to sociodemographic variables.

Methods: This is an ecological study, the study population of which consisted of autochthonous ACL cases notified in the municipalities of Acre by an epidemiological surveillance system.

Epidemiological aspects of American cutaneous leishmaniasis (ACL) in an endemic area of forest extractivist culture in western Brazilian Amazonia.

The study sought to analyze clinical and epidemiological aspects of cutaneous leishmaniasis (CL) in Xapuri, Acre, Brazil. Data from 2008 to 2014 registered in the notification records of the disease of the Information System of the Complaints of Notification (SINAN), and the data of the Information Department of the Unified Health System (DATASUS) available from 2007 to 2013 were used and analyzed in the light of the statistics of the temporal series by the Prais-Winsten method and chi-squared test. A total of 906 cases were registered with 60.
