Tropical Data: Approach and Methodology as Applied to Trachoma Prevalence Surveys.

Purpose: Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work to undertake those surveys.

Methods: Tropical Data is a consortium of partners that supports health ministries worldwide to conduct globally standardised prevalence surveys that conform to World Health Organization recommendations.

Knowledge, Attitudes, and Practices of Hygiene and the Prevention of Trachoma in the Indigenous Population of the Colombian Amazon Vaupés Department.

The Colombian program to end trachoma implements the component F of the SAFE strategy in the Vaupés department of the Amazon rainforest. Cultural, linguistic, and geographical barriers and the coexistence of an ancestral medical system demand the technical and sociocultural adaptation of this component. A cross-sectional survey combined with focus-group discussions to understand the knowledge, attitudes, and practices of the indigenous population related to trachoma was conducted in 2015.

Effectiveness of the CoronaVac® vaccine in a region of the Colombian Amazon, was herd immunity achieved?

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.

High Prevalence of SARS-CoV-2 in an Indigenous Community of the Colombian Amazon Region.

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.

Efficacy and safety of dimeticones in the treatment of epidermal parasitic skin diseases with special emphasis on tungiasis: an evidence-based critical review.

Epidermal parasitic skin diseases encompass scabies, pediculosis, cutaneous larva migrans, myiasis, and tungiasis. Tungiasis is probably the most neglected of all Neglected Tropical Diseases (NTD). It occurs in South America, the Caribbean and Sub-Saharan Africa and affects marginalized populations where people live in extreme poverty.

Very severe tungiasis in Amerindians in the Amazon lowland of Colombia: A case series.

Background: Tungiasis is a parasitic skin disease caused by penetrating female sand fleas. By nature, tungiasis is a self-limiting infection. However, in endemic settings re-infection is the rule and parasite load gradually accumulates over time.

In Situ Diagnosis of Scabies Using a Handheld Digital Microscope in Resource-Poor Settings-A Proof-of-Principle Study in the Amazon Lowland of Colombia.

Scabies is a neglected tropical disease associated with important morbidity. The disease occurs worldwide and is particularly common in resource-poor communities in the Global South. A validated technique for the diagnosis of scabies in resource-poor settings does not exist.

[Clinical evidence of trachoma in Colombian Amerindians of the Vaupés Province].

Introduction: Trachoma is the leading cause of infectious blindness in the world. In 2008 there were 1,300,000 persons with blindness caused by trachoma and 8 million with trichiasis, which might eventually lead to blindness. In Latin America it has been documented in Brazil, Guatemala and México.

[Tungiasis in native Amerindians in Vaupés province: epidemiology, clinical aspects, treatment, and prevention].

Introduction: Tungiasis, the skin infestation with the flea Tunga penetrans, occurs in poor communities. Objective. To present a study of this condition among native Amerindians from Vaupés (Colombia).
