“…An epidemiological study evaluating two nearby regions, with the same climatic conditions during the same EWs, found different prevalences of 57�1% and 45�7% [25]. This difference in seroprevalence in areas with similar climatic and geographical characteristics is possibly related to several factors, such as population density, sampling type, degree of vector mosquito infestation, sanitary structure of neighborhoods, and commercial activity in the city [10,11,25].…”

Background Chikungunya fever (CHIKF) is a serious public health problem with a high rate of infection and chronic disabling manifestations that has affected more than 2 million people worldwide since 2005. In spite of this, epidemiological data on vulnerable groups such as Indigenous people are scarce, making it difficult to implement public policies in order to prevent this disease and assist these populations. Objective To describe the serological and epidemiological profile of chikungunya virus (CHIKV) in two Indigenous populations in Northeast Brazil, as well as in an urbanized control community, and to explore associations between CHIKV and anthropometric variables in these populations. Methodology/Principal findings This is a cross-sectional ancillary study of the Project of Atherosclerosis among Indigenous Populations (PAI) that included people 30 to 70 years old, recruited from two Indigenous tribes (the less urbanized Fulni-ô and the more urbanized Truká people) and an urbanized non-Indigenous control group from the same area. Subjects underwent clinical evaluation and were tested for anti-CHIKV IgG by enzyme-linked immunosorbent assay. Serological profile was described according to ethnicity, sex, and age. The study population included 433 individuals distributed as follows: 109 (25·2%) Truká, 272 (62·8%) Fulni-ô, and 52 (12%) from the non-Indigenous urbanized control group. Overall prevalence of CHIKV IgG in the study sample was 49.9% (216; 95% CI: 45·1–54·7). When the sample was stratified, positive CHIKV IgG was distributed as follows: no individuals in the Truká group, 78·3% (213/272; 95% CI: 72·9–83·1) in the Fulni-ô group, and 5.8% (3/52; 95% CI: 1.21–16) in the control group. Conclusions/Significance Positive tests for CHIKV showed a very high prevalence in a traditional Indigenous population, in contrast to the absence of anti-CHIKV serology in the Truká people, who are more urbanized with respect to physical landscape, socio-cultural, and historical aspects, as well as a low prevalence in the non-Indigenous control group, although all groups are located in the same area.

“…The seroprevalence found for Mammarenavirus of the Tacaribe complex (1,64%) was comparable to that found in other studies carried out in human population in the country. Percentages between 0.5% and 3.1% had been described in indigenous populations and inhabitants of rural areas [3,5], indicating the circulation of these viruses between people who live in areas far from cities and who have contact with wild rodents such as those belonging to the Cricetidae family and the Sigmodontine subfamily. It should be clarified that although the seroprevalence values are low, they are similar to those found in other regions of the continent where important outbreaks of disease have occurred in humans [17].…”

“…In Colombia, no cases of Mammarenavirus fever have been reported due the absence of appropriated diagnostic infrastructure and its symptoms could be confused with those produce by other endemic agents as dengue, malaria, among others. However, previous studies have shown the circulation of Mammarenavirus in both rodents and humans [2][3][4][5]. Additionally, the high diversity of rodent species found in Colombia and the results of previous study that identified seropositive Zygodontomys brevicauda reservoirs of Guaranito virus, indicates the potential presentation of human cases in the territory [4,6].…”

Migration and urbanization processes contribute to the dispersion of pathogens, especially those with possible epizootic cycles, gaining importance in new populated areas. This panorama gets worst in developing countries like Colombia that still has limited capacity in strong epidemiological surveillance for noncommon microbial agents.Aim: This study evaluated the presence of IgG antibodies against Mammarenavirus from Tacaribe complex, Hepatitis E virus and HTLV type I or II in patients who visited the health center of a Montelibano (Cordoba), a rural-urban municipality of Colombia.Methods: ELISA's test carried out on 182 patients from Montelibano, Colombia in order to detect IgG antibodies. The sero-epidemiological study for IgG detection was conducted using Junin virus antigen, a HEV and an indirect HTLV-I/II Enzime-Linked Immunosorbent Assay, respectively.Results: Serological analysis allowed the detection of IgG antibodies for all the agents evaluated. Seroprevalence of IgG was 1.64% for the Mammarenavirus, 0,61% for the Hepatitis E and 0.61% for HTLV type 1 or 2. Conclusions:The results indicate the circulation of Mammarenavirus, Hepatitis E and HTLV in Montelibano, a municipality in the northeast of Colombia. Current seropositive percentage is similar or lower in comparison to other studies nevertheless epidemiological conditions like the presence of rodents at home and poor garbage collection services underline the necessity of better surveillance of these neglected viruses of which sporadic outbreaks have been reported.
