RESUMEN
BACKGROUND: The ability of SARS-CoV-2 to remain in asymptomatic individuals facilitates its dissemination and makes its control difficult. OBJECTIVE: To establish a cohort of asymptomatic individuals, change to the symptomatic status, and determine the most frequent clinical manifestations. METHODS: Between April 9 and August 9, 2020, molecular diagnosis of SARS-CoV-2 infection was confirmed in 154 asymptomatic people in contact with subjects diagnosed with COVID-19. Nasopharyngeal swabs were performed on these people in different hospitals in Córdoba, the Caribbean area of Colombia. The genes E, RdRp, and N were amplified with RT-qPCR. Based on the molecular results and the Cq values, the patients were subsequently followed up through telephone calls to verify their health conditions. RESULTS: Overall, of 154 asymptomatic individuals, 103 (66.9%) remained asymptomatic, and 51 (33.1%) changed to symptomatic. The most frequent clinical manifestations in young people were anosmia and arthralgia. Adults showed cough, ageusia, and odynophagia; in the elderly were epigastralgia, dyspnea, and headache. Mortality was 8%. CONCLUSIONS: A proportion of 33% of presymptomatic individuals was found, of which four of them died. This high rate could indicate a silent transmission, contributing significantly to the epidemic associated with SARS-CoV-2.

BACKGROUND: Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) is an emerging viral pandemic disease. In the last 6 months, SARS-CoV-2 has caused millions of reported cases and hundreds of thousands of deaths. As other world regions, South America has not contained the pandemic's advance since it lacks the hospital and economic capacities. Public health implications of transmission, while the asymptomatic/presymptomatic infection is a critical concern at the current pandemic. OBJECTIVE: Describe the socio-demographic, clinical, and viral features of a cohort of SARS-CoV-2 infected individuals from the Colombian Caribbean. METHODS: Six hundred eighty-six clinical samples of suspected SARS-CoV-2 infection cases and contacts individuals from several hospital centers in the department of Córdoba, Colombia, were received at our laboratory between April 9th and May 16th, 2020. RNA was extracted using lysis buffers and spin columns. The samples were tested for SARS-CoV-2 by reverse transcription real-time polymerase chain reaction (RT-qPCR) using commercially available multiplex real-time PCR assay for simultaneous detection of 3 target genes of SARS-CoV-2 (Allplex™, 2019-nCoV assay, Korea). Viral copies quantification was done using a standard curve constructed from seriated dilutions of a SARS-CoV-2 positive control. Statics descriptive methods were used. RESULTS: Thirty-five nasopharyngeal samples were positive for SARS-CoV-2 infection; the average age was 43 (range, 1-95 years). Seventeen of 35 (49%) of the patients showed symptoms. Most of them had a cough, fever, and odynophagia; three of the patients reported having arthralgia. Only two patients required hospitalization. None of the patients had known co-morbidities. RT-qPCR results show that two of the symptomatic patients had significantly higher RNA copies than the rest. Eighteen of 35 (51%) individuals were asymptomatic, and the average age was 30 (range, 6-61 years). Four asymptomatic individuals showed a higher copy than some symptomatic patients; nonetheless, the average of RNA copies 8.26 × 1010 was lower than the symptomatic. CONCLUSIONS: This study shows that asymptomatic patients may develop infections with a high number of RNA copies. Since a considerable percentage of infections may be asymptomatic/presymptomatic, enhanced testing approaches may be needed to detect these persons. Due the occurrence of a large proportion of infections being a result from transmission originated in asymptomatic/presymptomatic individuals, public health interventions in Colombia should be based on two steps: a massive molecular screening, and viral load quantification. Finally, a remarkable issue in our study is the average age of symptomatic and asymptomatic groups (43 and 30 respectively) which may be important because of the economic impact that has been caused by the coronavirus pandemic and may be probably the cause of the reduced lethality observed in the country and the department at the time of this study.

The Clinician Scholars Program (CSP) was designed to expand the HIV care workforce by improving the clinical capacity of clinicians in underserved areas. This evaluation assessed program participants' long-term practice changes and system changes. The year-long program combined mentoring, training, and on-site clinical observation. Qualitative interviews (N = 46) were conducted with Scholars at least 2 years following CSP, supplemented by a 2023 survey. Multiple coders analyzed transcripts using open coding. Thematic analysis explored practice changes and efforts to move patients along the HIV care continuum. Findings indicate positive long-term impacts of CSP regarding the HIV care continuum and care system engagement. Over 90% of Scholars remained working in HIV care, with 75% maintaining or increasing patient loads and 72% making changes to their clinical practice. This training model appears to enhance care along the HIV care continuum and may be adaptable to other contexts that address complex chronic conditions.

BACKGROUND: Ticks are obligate hematophagous ectoparasites involved in transmitting viruses of public health importance. The objective of this work was to identify the Jingmen tick virus in hard ticks from the Colombian Caribbean, an arbovirus of importance for public health. METHODS: Ticks were collected in rural areas of Córdoba and Cesar, Colombia. Taxonomic identification of ticks was carried out, and pools of 13 individuals were formed. RNA extraction was performed. Library preparation was performed with the MGIEasy kit, and next-generation sequencing (NGS) with MGI equipment. Bioinformatic analyses and taxonomic assignments were performed using the Galaxy platform, and phylogenetic analyses were done using IQ-TREE2. RESULTS: A total of 766 ticks were collected, of which 87.33% (669/766) were Rhipicephalus microplus, 5.4% (42/766) Dermacentor nitens, 4.2% (32/766) Rhipicephalus linnaei, and 3.0% (23/766) Amblyomma dissimile. Complete and partial segments 1, 2, 3, and 4 of Jingmen tick virus (JMTV) were detected in the metatranscriptome of the species R. microplus, D. nitens, and A. dissimile. The JMTVs detected are phylogenetically related to JMTVs detected in Aedes albopictus in France, JMTVs detected in R. microplus in Trinidad and Tobago, JMTVs in R. microplus and A. variegatum in the French Antilles, and JMTVs detected in R. microplus in Colombia. Interestingly, our sequences clustered closely with JMTV detected in humans from Kosovo. CONCLUSIONS: JMTV was detected in R. microplus, D. nitens, and A. dissimile. JMTV could pose a risk to humans. Therefore, it is vital to establish epidemiological surveillance measures to better understand the possible role of JMTV in tropical diseases.

BACKGROUND: The genus Borrelia comprises pathogenic species of bacteria that pose a significant risk to public health. Borrelia spp. are emerging or reemerging infectious agents worldwide with complex transmission cycles, and many species use rodents as vertebrate reservoir hosts. Spirochetes morphologically compatible with Borrelia have been recurrently observed in opossums; however, there is currently a lack of genetic evidence confirming infection or supporting that these marsupials are hosts of Borrelia spirochetes. METHODS: During 2017, 53 serum samples of Didelphis marsupialis from the municipality of Colosó (department of Sucre, Colombia) were collected and allocated in a serum bank. DNA extracted from the serum samples was submitted to a Borrelia genus-specific real-time PCR targeting the 16S rRNA gene. Positive samples were subsequently derived from semi-nested PCR protocols to obtain large fragments of the 16S rRNA and flaB genes. Obtained amplicons were subjected to Sanger sequencing. One positive sample was randomly selected for next-generation sequencing (NGS). Obtained reads were mapped to genomes of Borrelia spp. and sequences of two genes used in a multilocus sequence typing scheme retrieved for taxonomic assignment and phylogenetic analyses. RESULTS: Overall, 18.8% (10/53) of the samples were positive by qPCR. Of them, 80% (8/10) and 60% (6/10) were positive for the 16S rRNA and flaB genes after semi-nested PCRs, respectively. Bioinformatic analysis of one sample sequenced with NGS yielded 22 reads of genus Borrelia with different sizes. Two housekeeping genes, rplB and pyrG, were recovered. Nucleotide pairwise comparisons and phylogenetic analyses of 16S rRNA, flaB, rplB and pyrG genes showed that the Borrelia sp. found in opossums from Colosó corresponded to Borrelia puertoricensis. CONCLUSIONS: We describe the first molecular evidence to our knowledge of B. puertoricensis in Colombia, specifically in opossums, and the first detection of this spirochete in a vertebrate host since its isolation from Ornithodoros puertoricensis in Panama. This detection is also relevant because of the epidemiological importance of opossums as reservoirs of zoonotic diseases to humans.

BACKGROUND: The emergence of highly transmissible SARS-CoV-2 variants has led to surges in cases and the need for global genomic surveillance. While some variants rapidly spread worldwide, other variants only persist nationally. There is a need for more fine-scale analysis to understand transmission dynamics at a country scale. For instance, the Mu variant of interest, also known as lineage B.1.621, was first detected in Colombia and was responsible for a large local wave but only a few sporadic cases elsewhere. METHODS: To better understand the epidemiology of SARS-Cov-2 variants in Colombia, we used 14,049 complete SARS-CoV-2 genomes from the 32 states of Colombia. We performed Bayesian phylodynamic analyses to estimate the time of variants' introduction, their respective effective reproductive number, and effective population size, and the impact of disease control measures. RESULTS: Here, we detect a total of 188 SARS-CoV-2 Pango lineages circulating in Colombia since the pandemic's start. We show that the effective reproduction number oscillated drastically throughout the first two years of the pandemic, with Mu showing the highest transmissibility (Re and growth rate estimation). CONCLUSIONS: Our results reinforce that genomic surveillance programs are essential for countries to make evidence-driven interventions toward the emergence and circulation of novel SARS-CoV-2 variants.
Colombia reported its first COVID-19 case on 6th March 2020. By April 2022, the country had reported over 6 million infections and over 135,000 deaths. Here, we aim to understand how SARS-CoV-2, the virus that causes COVID-19, spread through Colombia over this time and how the predominant version of the virus (variant) changed over time. We found that there were multiple introductions of different variants from other countries into Colombia during the first two years of the pandemic. The Gamma variant was dominant earlier in 2021 but was replaced by the Delta variant. The Mu variant had the highest potential to be transmitted. Our findings provide valuable insights into the pandemic in Colombia and highlight the importance of continued surveillance of the virus to guide the public health response.
RESUMEN
INTRODUCTION: Currently, more than 4.5 billion doses of SARS-CoV-2 vaccines have been applied worldwide. However, some developing countries are still a long way from achieving herd immunity through vaccination. In some territories, such as the Colombian Amazon, mass immunization strategies have been implemented with the CoronaVac® vaccine. Due to its proximity to Brazil, where one of the variants of interest of SARS-CoV-2 circulates. OBJECTIVE: To determine the effectiveness of the CoronaVac® vaccine in a population of the Colombian Amazon. METHODS: Between February 24, 2021, and August 10, 2021, a descriptive observational study was carried out in which a population of individuals over 18 years of age immunized with two doses of the CoronaVac® vaccine was evaluated. The study site was in the municipality of Mitú, Vaupés, in southeastern Colombia, a region located in the Amazon bordering Brazil. RESULTS: 99% of the urban population of the Mitú municipality were vaccinated with CoronaVac®. To date, 5.7% of vaccinated individuals have become ill, and only 0.1% of these require hospitalization. One death was attributable to COVID-19 has been reported among vaccinated individuals, and the vaccine has shown 94.3% effectiveness against mild disease and 99.9% against severe infection. CONCLUSIONS: The herd immunity achieved through mass vaccination in this population has made it possible to reduce the rate of complicated cases and mortality from COVID-19 in this region of the Colombian Amazon. HIGHLIGHTS: CoronaVac® has shown 94.3% effectiveness against mild disease and 99.9% against severe infection in this indigenous population. CoronaVac® reduces the mortality rate from 2.2% in 2020 to 0.22% in 2021. The herd immunity was achieved through mass vaccination in this region of the Colombian Amazon.
RESUMEN
INTRODUCTION: Although more than half of the world's population is already vaccinated, the appearance of new variants of concern puts public health at risk due to the generation of new immunogens against the virus as a crucial and relevant strategy in the control of these new variants. METHODS: A preclinical study used a potential vaccine candidate (RBD, SARS-CoV-2). Four groups of BALB/c mice were used, a control group, an adjuvant group, a group inoculated with one dose of RBD subunit protein, and the fourth group inoculated with two doses of RBD subunit protein. RESULTS: No inflammatory or cellular changes were shown in the mice's anatomopathological evaluation. Higher kinetics and 75% seroconversion were obtained in the mice inoculated with two doses of RBD (Pâ¯<â¯0.0001). CONCLUSIONS: The application of two doses of the RBD vaccine candidate in BALB/c mice proved safe and immunogenic against SARS-CoV-2.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent of the current COVID-19 pandemic, has evolved to have a wide range of hosts, including non-human primates, wild and domestic animals. The ACE2 protein has a high level of conservation and is the common receptor invertebrate species for a viral infection to occur; this receptor could give rise to anthroponotic events. This article describes the first event of symptomatic transmission in Latin America from a human to a dog by the B.1.625 lineage of SARS-CoV-2. We found 21 shared mutations in the complete genomes of viral sequences from owners and dogs. Further phylogenetic and molecular analysis showed that 100% co-localization of the clade helps to understand human-animal transmission. Prediction of the Spike protein structure of the sequenced virus and docking analyzes showed that the E484K mutation in the receptor-binding domain (RBD) could contribute to the viral affinity of dACE2. Therefore, close contact between SARS-CoV-2-infected humans and pets should be avoided to prevent the emergence of novel mutations of public health importance from anthroponotic events.

BACKGROUND: Serological evaluation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an alternative that allows us to determine the prevalence and dynamics of this infection in populations. The goal of this study was to determine the clinical and sociodemographic dynamics of SARS-CoV-2 infection in a region of the Colombian Caribbean. METHODS: Between July and November 2020, a cross-sectional observational study was carried out in Córdoba, located in northeast Colombia in the Caribbean area. Eight municipalities with the largest populations were chosen and 2564 blood samples were taken. A commercial enzyme-linked immunosorbent assay was used with the recombinant protein antigen N of SARS-CoV-2. The people included in the study were asked for sociodemographic and clinical data, which were analysed by statistical methods. RESULTS: A seroprevalence of 40.8% was obtained for SARS-CoV-2 in the Córdoba region. In the bivariate analysis, no differences were observed in seropositivity against SARS-CoV-2 for gender or age range (p>0.05). Higher seropositivity was found in low socio-economic status and symptomatic patients (p<0.0001). A total of 30.7% of the asymptomatic patients were seropositive for SARS-CoV-2, which could be linked to the spread of this infection. In the multivariate analysis, seroconversion was related to poverty and clinical manifestations such as anosmia and ageusia (p<0.05). CONCLUSIONS: The high seropositivity in Córdoba is due to widespread SARS-CoV-2 in this population. The relationship between seropositivity and socio-economic status suggests a higher exposure risk to the virus caused by informal economic activities in low-income groups. Clinical manifestations such as anosmia and ageusia could be clinical predictors of infection by the new emergent coronavirus.

Introduction. COVID-19 is a pathology caused by the SARS-CoV-2 virus. The World Health Organization (WHO) has reported more than 225 million cases and 4.5 million deaths worldwide. Objective: To describe the seropositivity, spatial distribution, and clinical and sociodemographic variables of SARS-CoV-2 in a community of the Colombian Amazon region. Methods. In December 2020, a cross-sectional observational study was carried out in a population located in the Colombian Amazon in the municipality of Mitú. Sociodemographic and clinical data were taken. Besides, 589 blood samples were taken, and an antibody detection was carried out with an ELISA and a recombinant protein N antigen of SARS-CoV-2. Results. A seropositivity of 57.6% was observed. The highest proportion of the infection is located in inter-municipal transport zones. The bivariate analysis did not show differences in the SARS-CoV-2 infection rate concerning the variables sex, age range, and the presence of comorbidities (p > 0.05). The bivariate and multivariate analysis showed that being symptomatic and presenting neurological manifestations of the upper respiratory tract are clinical variables associated with SARS-CoV-2 infection (p < 0.05). One of the causes of this virus's high spread in this community could be that 53.3% of the people were asymptomatic. Conclusions. Our data showed a high burden and transmission of SARS-CoV-2 in the indigenous community. This could be linked to cultural behaviors and the high infection rate in asymptomatic patients.
RESUMEN
A serological survey was carried out in Monteria (500â 000 population), a mid-size city in Colombia. An overall prevalence of 55.3% (95% confidence interval, 52.5%-57.8%) was found among a sample of 1.368 people randomly selected from the population. Test positivity was related to economic characteristics with the highest prevalence found in the most impoverished areas, representing 83.8% of the city's population. We found a prevalence that might be associated with some important level of population immunity.
RESUMEN
OBJECTIVES: We investigated seroreactivity by using a commercial SARS-CoV-2 ELISA test in samples collected from different groups of individuals, including patients diagnosed to have Dengue, Zika, and Chikungunya infection between 2015 and 2019, from an endemic area in the Caribbean Colombian region. METHODS: A total of 127 sera samples obtained from six different groups of individuals were included in this study: Group A: patients with confirmed SARS-CoV-2 infection; Group B: patients with symptoms suggestive of COVID-19 or asymptomatic contacts with confirmed patients; Group C: patients with acute or recent dengue virus infection; Group D: patients with acute Zika virus infection; Group E: patients with previous Chikungunya virus infection; and Group F: individuals with exposure to spotted fever group rickettsiae. RESULTS: Overall, group A, group B, and group D showed seroreactivity to SARS-CoV-2 in 92%, 75%, and 26% of samples, respectively; furthermore, group C, group E, and group F showed 100% seronegativity. CONCLUSIONS: We found 26% of serological cross-reactivity in patients with acute Zika virus infection by using a commercial SARS-CoV-2 ELISA test. Further studies are needed to evaluate whether serological cross-reaction is maintained with time in nonacute patients with previous exposure to the Zika virus and its effect in SARS-CoV-2 serosurveys in endemic areas for this arbovirus.

INTRODUCTION: The Clinician Scholars Program is designed to improve the capacity and quality of HIV care by training clinicians in underserved areas. A mentoring approach is used to deliver individualized educational opportunities over the course of a year focused on preparing clinicians to provide high-quality patient-centered HIV care. Evaluation of the program has illustrated increases in knowledge, skills, and practice behavior, yet critical domains remain unexplored, particularly the potential for the program to affect professional identity formation and networking between individual clinicians. METHODS: Qualitative exit interviews (N = 50) were conducted over 4 years of the Clinician Scholars Program. Interviews were transcribed and analyzed using an open-coding process with multiple coders. Interrater reliability was assessed. Themes related to professional development and networking emerged. RESULTS: Thematic analysis revealed changes in several professional development domains, including self-efficacy, HIV care clinician identity, and career development. In addition, clinicians began to develop key connections with mentors, other clinicians, and health systems-gaining a foundation in the HIV care community, enabled and strengthened by growth in professional confidence and competence within the clinician's care context. DISCUSSION: Evaluations of clinical training programs often focus on knowledge and skill gains without addressing professional identity development and place within the care community. This study illustrates that a longitudinal clinician training program has the potential to influence professional identify development, particularly affect how clinicians view themselves as a resource in the HIV care community and begins to facilitate necessary connections to other clinicians and the wider care system.

The Clinician Scholars Program at the Midwest AIDS Training and Education Center strengthens the workforce by increasing knowledge and skills related to HIV prevention and care. The 1-year individualized training program for minority-serving clinicians includes intensive mentoring and networking. Qualitative exit interviews (N = 50) conducted over 4 years demonstrate the effectiveness of the training, including changes at the individual and systems levels. Findings show that almost all graduates reported improvements in knowledge, two-thirds reported changes in empathic capacity and cultural competence, and nearly three-quarters reported changes in clinical practice. Scholars indicated improvements in knowledge and practice of HIV prevention, including pre-exposure prophylaxis and managing medications and comorbidities. A third of the Scholars reported improvements in their clinical practices related to linking and retaining patients in HIV care, which demonstrated positive movement along the HIV care continuum, a key focus area of the National HIV AIDS Strategy.

Engaging new clinical providers in the HIV workforce is a critical need due to rapidly evolving treatment paradigms, aging out of existing providers, and special population needs. The 1-year competency-based Clinician Scholar Program for minority-serving providers with limited HIV care experience was individually tailored for each provider (n = 74), mostly nurse practitioners, physicians, and clinical pharmacists. Baseline and endpoint self-assessments of clinical knowledge and skills showed significant improvements in all 11 targeted competencies, particularly in managing antiretroviral medications, screening and testing methods, incorporating prevention into HIV care, understanding risk reduction methods, and describing current care standards. Faculty mentor assessments also showed significant improvement in most competencies. Additional benefits included ongoing access to mentorship and training, plus sustained engagement in local and statewide HIV care networks. Our intensive mentoring program model is replicable in other AIDS Education and Training Centers and in other structured training programs.

The Midwest AIDS Training and Education Center (MATEC) implemented a Web-based survey method to measure impact on practitioners of HIV/AIDS skill-building workshops offered in seven midwestern states. Surveys were sent to 2,949 participants from 230 workshops 4-6 weeks after each workshop. Of those surveyed, 631 respondents provided usable data (22.4%). Self-reported narrative responses described practice changes attributed to training. Changes were categorized as (a) practitioner attitude/knowledge, (b) practitioner practice behavior, (c) planning system change, and (d) implemented adaptations to the clinical care system. Other outcome measures were attending more programs and consulting with colleagues. Change was reported by 341 (54.0%) individuals, with a total of 411 change events/activities documented. Of the change events, 302 (73%) related to changes in health provider practices and 109 (27%) related to the care systems. Findings from this evaluation project provide evidence that MATEC workshops do impact practitioners' behaviors and care systems consistent with the literature about translating research into practice.

Background: hemangiomas are the most frequent benign tumors in childhood. In the 20 percent of the cases a hemangioma, during its growth, may provoke complications caused by compression and obstruction of important structures like the eyes, nose, mouth, and airways. A type of treatment is recommended for these patients.Objective: to provide an alternative for the treatment of complicated infantile hemangiomas with the use of propanolol taken orally.Method: a bibliographic review of the literature of the last five years about the treatment of complicated infantile hemangiomas with propanolol was made.Development: the common treatment for complicated infantile hemangiomas was made with systemic corticosteroids (prednisone taken orally, with a daily dose of 2 to 4 mg/kg during six weeks) and alternately with interferon-alpha-2b, laser, sclerotherapy, cytokines, radiotherapy, and cryosurgery. Nevertheless, some of these methods are very expensive and may cause significant systemic effects. Many studies indicate the effectiveness of the systemic propanolol in the treatment of complicated infantile hemangiomas with encouraging results and few side effects. Although the mechanism by means of which this medicament works is not well known, it is believed that it can be related to the control of cell hypoxia, the induction of apoptosis of the endothelial cells, and the inhibition of the endothelial and fibroblast growth factor. Most of the reviewed reports showed changes in the color and size of the lesions just a few weeks from its beginning.Conclusions: propanolol must be considered as the first line of treatment for complicated infantile hemangiomas because of its high effectiveness and safety. Its use is recommended in the secondary care level...

Background: hemangiomas are the most frequent benign tumors in childhood. In the 20 percent of the cases a hemangioma, during its growth, may provoke complications caused by compression and obstruction of important structures like the eyes, nose, mouth, and airways. A type of treatment is recommended for these patients.Objective: to provide an alternative for the treatment of complicated infantile hemangiomas with the use of propanolol taken orally.Method: a bibliographic review of the literature of the last five years about the treatment of complicated infantile hemangiomas with propanolol was made.Development: the common treatment for complicated infantile hemangiomas was made with systemic corticosteroids (prednisone taken orally, with a daily dose of 2 to 4 mg/kg during six weeks) and alternately with interferon-alpha-2b, laser, sclerotherapy, cytokines, radiotherapy, and cryosurgery. Nevertheless, some of these methods are very expensive and may cause significant systemic effects. Many studies indicate the effectiveness of the systemic propanolol in the treatment of complicated infantile hemangiomas with encouraging results and few side effects. Although the mechanism by means of which this medicament works is not well known, it is believed that it can be related to the control of cell hypoxia, the induction of apoptosis of the endothelial cells, and the inhibition of the endothelial and fibroblast growth factor. Most of the reviewed reports showed changes in the color and size of the lesions just a few weeks from its beginning.Conclusions: propanolol must be considered as the first line of treatment for complicated infantile hemangiomas because of its high effectiveness and safety. Its use is recommended in the secondary care level(AU)
