Tuberculosis contact tracing, Angola.

Objective: To assess the outcomes of a contact-tracing programme to increase the diagnosis of tuberculosis in Cubal, Angola and offer preventive treatment to high-risk groups.

Methods: A health centre-based contact-tracing programme was launched in Hospital Nossa Senhora da Paz in March 2015 and we followed the programme until 2022. In that time, staffing and testing varied which we categorized as four periods: medical staff reinforcement, 2015-2017, with a doctor seconded from Vall d'Hebron University Hospital, Spain; routine staff, 2017-2021, with no external medical support; community directly observed treatment (DOT), 2018-2019 with community worker support; and enhanced contact tracing, 2021-2022, with funding that allowed free chest radiographs, molecular and gastric aspirate testing.

Impact of traditional cutaneous scarification on anthrax lesions: A series of cases from Cubal, Angola.

Objectives: Bacillus anthracis infection is a worldwide zoonosis that affects the most vulnerable population and has a high mortality rate without treatment, especially in non-cutaneous presentations. Cutaneous scarification is still common in some regions of the world for the treatment of certain diseases as part of traditional medicine. We describe a series of cutaneus anthrax from a rural setting in Angola where cutaneus scarification is common.

Civil Engineering and Malaria Risk: A Descriptive Study in a Rural Area of Cubal, Angola.

(1) Background: Angola is among the high-burden countries with malaria cases globally. After 2013, we suspected an increase in the number of malaria cases in Cubal (Angola), previously in decline. Our objective was to evaluate the incidence rate in Cubal, overall and by neighborhood, for 2014, 2015, and 2016.

Old zoonotic agents and novel variants of tick-borne microorganisms from Benguela (Angola), July 2017.

Background: Ticks and tick-borne diseases constitute a real threat for the livestock industry, which is increasing in Angola. In addition, ticks are vectors of zoonoses of public health concern, and scarce information is available from this country. In an effort to contribute to the prevention of zoonotic infectious diseases affecting humans and animals, the molecular screening of certain tick-related microorganisms collected on cattle in Angola was performed under a 'One Health' scope.

Telemedicine experience between two hospitals from Angola and Spain.

Objective: Telemedicine uses information and communication technologies to provide services in the field where the distance is a critical factor. The aim of the present study is to describe the experience of a synchronous telemedicine between two hospitals in Spain and Angola.

Methods: This is a retrospective observational study of all synchronous telemedicine sessions conducted between the Hospital Nossa Senhora da Paz in Angola and the Vall d'Hebron University Hospital in Spain from January 2011 to December 2014.

Ultrasound Evolution of Pediatric Urinary Schistosomiasis after Treatment with Praziquantel in a Highly Endemic Area.

Urinary schistosomiasis causes damage to the urological system. Ultrasound is a method that detects the burden of secondary disease, individually and in epidemiological studies. In this study, the -associated urinary tract pathology is analyzed before and after treatment in a short period of time.

Field and laboratory comparative evaluation of a LAMP assay for the diagnosis of urogenital schistosomiasis in Cubal, Central Angola.

Objective: To evaluate the performance of Rapid-Heat LAMPellet assay in field conditions for diagnosis of urogenital schistosomiasis in an endemic area in Cubal, Angola, and to assess the reproducibility in a reference laboratory.

Methods: A total of 172 urine samples from school-age children were tested for microhaematuria, microscopic detection of Schistosoma haematobium eggs and LAMP for DNA detection. Urine samples were stored in a basic equipped laboratory.

Prevalence and molecular characterization of Strongyloides stercoralis, Giardia duodenalis, Cryptosporidium spp., and Blastocystis spp. isolates in school children in Cubal, Western Angola.

Background: Human infections by the gastrointestinal helminth Strongyloides stercoralis and the enteric protozoans Giardia duodenalis, Cryptosporidium spp. and Blastocystis spp. are not formally included in the list of 20 neglected tropical diseases prioritised by the World Health Organization.

Ultrasound findings and associated factors to morbidity in Schistosoma haematobium infection in a highly endemic setting.

Objective: To evaluate the usefulness of the WHO classification of ultrasound pathological changes and to establish risk factors for morbidity in a highly endemic setting.

Methods: One hundred and fifty-seven ultrasounds were performed on school-aged children previously diagnosed with urinary schistosomiasis in Cubal, Angola. The findings were analysed according to the WHO guidelines.

Prevalence of and Other Intestinal Parasite Infections in School Children in a Rural Area of Angola: A Cross-Sectional Study.

is widely distributed in the tropics and subtropics.

A cross-sectional study was conducted in school-age children (SAC) in Cubal, Angola.

Epidemiology of Schistosomiasis and Usefulness of Indirect Diagnostic Tests in School-Age Children in Cubal, Central Angola.

Introduction: Schistosomiasis remains a public health major problem and little is known in many areas, mainly in Sub-Saharan Africa.

Methods: A cross-sectional study was conducted.

Changes in malaria epidemiology in a rural area of Cubal, Angola.

Background: Scarce information about malaria epidemiology in Angola has been published. The objective of this study is to describe the epidemiology of malaria at the Hospital Nossa Senhora da Paz (Cubal, Angola) and the fatality rate due to malaria (total and in children under five years) in the last five years.
