Socioeconomic vulnerability associated with toxocariasis exposure in southern Brazil
Introduction Although toxocariasis has been listed among the five most neglected parasitic infections worldwide, with higher impact in socioeconomically vulnerable populations, no study has evaluated vulnerable individuals from highly populated urban areas. Methods Accordingly, human serum samples were collected in Curitiba, the eighth most populated metropolitan area of Brazil, and tested by indirect enzyme-linked immunosorbent assay (ELISA) for…
Coxiella burnetii (Q fever) exposure in recycling, non-recycling workers and dogs in a major urban area of Brazil
Introduction: Q fever has been considered a worldwide zoonosis caused by Coxiella burnetii, mostly transmitted by respiratory routes in contaminated environments with bio logical waste. Although urban recycling facilities may concentrate contaminated materials, their significance as potential environmental sources for C. burnetii infection has not been investigated to date. Methods: Accordingly, the aim of this study was to assess previous exposu…
One Health approach to Coxiella burnetii
Coxiella burnetii , the causative agent of Q fever, a zoonotic pathogen with primarily airborne transmission and diverse host species, have been reported in serosurveys of vulnerable populations worldwide. Although vulnerable populations from oceanic islands and mainland seashore areas in Brazil may be also exposed C. burnetti , no study to date has concomitantly assessed owners and dogs in such environmental setting. Accordingly, the present stu…
Mapping vulnerability for increased Covid-19 susceptibility and worse outcomes
Introduction: Infectious diseases can spread rapidly in the globalized world, and the complex intersection of individual, social, economic, and cultural factors make it difficult to identify vulnerabilities in the face of pandemics. Methods: Therefore, this study aimed to identify vulnerability factors to infection and worse outcomes associated with COVID-19. This is a scoping review study of six databases that selected publications between 2019 …
Coxiellaburnetii (Q fever) exposure in wildlife professionals
Introduction Although occupational exposure to Coxiella burnetii has been studied previously, the zoonotic risk in wildlife environments remains unclear and has yet to be fully established. Methods Accordingly, the present study aimed to serologically assess professionals with daily contact with free-living and captive wildlife in Paraná State, Brazil, along with the potential associated risk factors for C. burnetii exposure. Results Overall, 25 …
One Health Index applied to countries in South America
Introduction: The One Health concept has proposed an integrated and unified approach aiming for health balance and enhancement by recognizing the interdependence of human, animal, and environmental health. The COVID-19 pandemic has pushed global One Health initiatives and policy improvement toward preventive measures for future pandemics, particularly of zoonotic origin. Such a scenario may be particularly relevant for South America, which is con…
One health approach to toxocariasis in Brazilian indigenous populations, their dogs, and soil contamination
Introduction Although socioeconomic vulnerability and lifestyle factors may contribute to the transmission of Toxocara spp., no study has investigated indigenous populations in Brazil using the One Health approach. Methods Accordingly, this study assessed anti- Toxocara spp. antibodies in Brazilian indigenous people and healthcare professionals by enzyme-linked immunosorbent assay. Presence of Toxocara spp. eggs (feces and hair) in dogs as defini…
Cat rabies in Brazil
This review of human and cat rabies from 1986 to 2022 has shown mostly AgV3 variant in human cases with 29/45 (64.4%) reports including 23 from bats, four from cats, and two from unknown species, followed by 8/45 (17.8%) of AgV2 variant (all from dogs), 4/45 from marmoset variant (all from Callithrix jacchus ), 2/45 samples compatible with wild canid variant (both from Cerdocyon thous ), and one/45 of AgV1 variant from a domestic dog. Only one sa…
Serosurvey of Trypanosoma cruzi in persons experiencing homelessness and shelter workers of Brazil
Although Chagas disease, caused by Trypanosoma cruzi , has been associated with social vulnerability worldwide, producing disability and mortality, no study to date has assessed this protozoal infection in persons experiencing homelessness. Accordingly, the present study aimed to assess anti- T. cruzi antibodies by Wiener Chagatest ELISA recombinant v.3.0 in serum samples of persons experiencing homelessness and related shelter workers in São Pau…
Dog and Cat Contact as Risk Factor for Human Toxocariasis
Toxocariasis, a neglected parasitic zoonosis with worldwide distribution, has been reportedly associated to different risk factors in several epidemiological and meta-analysis studies. However, dog and cat contact (environmental and animal exposure) as isolated associated risk factor for children and adults remains to be fully established. Accordingly, the present meta-analysis has aimed to directly assess dog and cat contact for toxocariasis ser…
A Novel Host of an Emerging Disease
From the Approach to the Concept
Professionals throughout the world have been working to assess the interdisciplinary interaction and interdependence between health and wellbeing in a constantly changing environment. The One Health concept was developed to encourage sustainable collaborative partnerships and to promote optimal health for people, animals, plants, the environment, and the whole planet. The dissemination of scientific discoveries and policies, by working directly w…
Serosurvey of Anti-Toxoplasma gondii Antibodies in Homeless Persons of São Paulo City, Southeastern Brazil
Seroprevalence of Toxoplasma gondii has been extensively studied in a variety of different human populations. However, no study has focused on homeless populations. Accordingly, the present study aimed to assess the seroprevalence of anti-T. gondii antibodies and the risk factors associated in homeless persons from homeless shelter of So Paulo city, southeastern Brazil. In addition, anti-HIV antibodies and associated risk of T. gondii and HIV coi…
Frequency and spatial distribution of animal and object hoarder behavior in Curitiba, Paraná State, Brazil
This study aimed to establish the frequency and spatial distribution of animal and object hoarding in Curitiba (Paraná State), the eighth most populous city in Brazil. All hoarding complaints received by the City Secretaries of Health, Environment and Social Assistance between September 2013 and April 2015 were collected (n = 226) and suspicious cases were individually investigated. A total of 113/226 (50%) of complaints were confirmed as hoardin…
Neighborhood and postal worker characteristics associated with dog bites in postal workers of the Brazilian National Postal Service in Curitiba
Dog bites are the third most common cause of absenteeism among postal workers of the Brazilian National Postal Service in Southern Brazil, with an average off-work time of approximately two days for each biting episode. The objective of this study was to evaluate the neighborhood characteristics involving dog bites that occurred during work time in postal workers, its impact on work and consequent preventive alternatives. A descriptive and analyt…
