  • Assessing the impact of childhood pneumococcal vaccination on pneumonia mortality in Colombia

    Open AccessC Parellada, Luis Felipe Reyes et al.ARTICLEBMC Public Health2025

    The 10-valent pneumococcal conjugate vaccine (PCV10) has been offered to all infants through Colombia’s National Immunization Program (NIP) since 2012, with catch-up vaccination until age 5. However, pneumococcal vaccination is not currently included in the NIP for other age groups, such as those ≥ 5 years with medical conditions or older adults. This study assessed the pediatric PCV10 effect on pneumonia mortality rate (MR) trends across differe…

  • Biotechnological sovereignty is not a mere nationalist concept, it is a necessity for Colombia and Latin America

    Open AccessCamilo Guzman, Salim Mattar et al.ARTICLECadernos de Saude Publica2024References: 11

    During the pandemic, Latin American countries suffered the collapse of their health systems. This was caused by the high demand for care of patients infected with SARS-CoV-2, which was added to the care of patients with other diseases. The significant increase in demand for health services caused medical and laboratory supplies to decline rapidly. The COVID-19 pandemic exacerbated a health crisis in several developing countries, mainly caused by …

  • Seroprevalence of Hepatitis E virus in children and adolescents living in urban Bogotá

    Open AccessNathalie Fernández Villalobos, Nathalie Verónica Fernández Villalobos et al.ARTICLEFrontiers in Public Health2023

    The majority of Hepatitis E Virus (HEV)-related studies are carried out in adults whereas information about HEV seroprevalence, clinical disease manifestation, molecular epidemiology, and transmission patterns in children is limited. To estimate HEV seroprevalence among scholar children living in an urban setting and to analyze risk factors for an infection, we invited children aged 5–18 years from Bogotá (Colombia) for a cross-sectional survey. …

  • Sars-CoV-2 Infection among School Population of One Developing Country. Do School Closures Protect Students and Teachers against Sars-CoV-2 Infection

    Open AccessCarol B Colonia, Rosanna Camerano Ruiz et al.ARTICLEInternational Journal of…2021

    Evidence about the effectiveness of school closures as a measure to control the spread of COVID-19 is controversial. We posit that schools are not an important source of transmission; thus, we analyzed two surveillance methods: a web-based questionnaire and a telephone survey that monitored the impact of the pandemic due to COVID-19 cases in Bogotá, Colombia. We estimated the cumulative incidences for Acute Respiratory Infection (ARI) and COVID-1…

  • Effectiveness of a prevention program in the incidence of cardiovascular outcomes in a low-income population from Colombia

    Open AccessPablo Andrés Miranda Machado, Fernando Salcedo‐Mejía et al.ARTICLEBMC Public Health2020

    The DTC program is effective in the reduction of the risk of CVOs. Population-based interventions may be an important strategy for the prevention of CVOs in underserved populations in the context of LMICs. A more exhaustive emphasis on the control of diabetes mellitus should be considered in these strategies

  • Burden of disease due to microcephaly associated with the Zika virus in Colombia

    Open AccessAndrés Felipe Mora-Salamanca, Alexandra Porras-Ramírez et al.ARTICLECadernos de Saude Publica2020References: 20

    In 2015, the Zika virus was introduced in Colombia. The emergence of this arbovirus is a public health challenge for the country, considering the association between the infection and congenital disorders such as microcephaly. Thus, we estimated the burden of disease due to microcephaly associated with Zika in Colombia and its administrative subdivisions for the period 2015-2016. We conducted an exploratory ecological study, using as unit of meas…

  • Costo-efectividad de la vacunación contra influenza pandémica en mujeres embarazadas en Colombia

    Open AccessLuz Angela Chocontá-Piraquive, Nelson Alvis Guzman et al.ARTICLERevista Panamericana de Salud…2012

    Vaccinating pregnant women against pandemic influenza is cost-effective in a scenario with a high mortality rate. The existing evidence that pregnant women are at increased risk of complications and that the vaccine is safe would justify its use in pregnant women

  • Impacto epidemiológico y económico de la vacunación contra el tétanos en adultos de Colombia

    Open AccessNelson Alvis-Guzman, Nelson Alvis et al.ARTICLERevista Panamericana de Salud…2011

    This is the first study that evaluates the cost-effectiveness of a tetanus vaccine booster dose every 10 years in a developing country. Use of this measure would be cost-effective in Colombia, especially for men. As a result of the gender-based differences in the results, any decision about its use in women of childbearing age should take current vaccination into account

  • SP5-13 Socioeconomic aspects associated to malaria in pregnancy in Colombia

    J G P Jiménez, S B Trujillo et al.ARTICLEJournal of Epidemiology and…2011

    Background Income, education, work and access to prevention measures have been identified as socioeconomic aspects related to malaria. For groups at risk such as pregnant women these aspects are little known, particularly outside Africa. The objective of this study was to determine socioeconomic aspects of pregnant women associated to malaria in a Latinamerican region. Methods A case-control study was conducted from April 2005 to December 2006 in…

  • Data and Code for Covid-19 spread, detection, and dynamics in a megacity in Latin America

    Rachid Laajaj, Camilo De Los Rios et al.

    We implemented a COVID-19 sentinel surveillance study with 59,770 RT-PCR tests on mostly asymptomatic individuals and combine this data with administrative records on all detected cases to capture the spread and dynamics of the COVID-19 pandemic in Bogotá from June 2020 to early March 2021. We describe various features of the pandemic that appear to be specific to a developing-country context. We find that, by March 2021, slightly more than half …
