The public transportation fare in a city is an important determinant of accessibility, equity, and quality of life for its citizens. This article makes a comparative quantitative analysis of the fare of the public transportation system in the city of Bogotá (Colombia), its evolution over time, and the impact on the poorest users. It compares with similar systems in Latin America and other cities in the world. The findings show that the fare has had high growth in US dollars (USD 0.38 in 2000 to 0.75 in 2024), but the purchasing capacity has increased with respect to the local minimum wage (10.84 tickets with a minimum daily wage, versus 14.69 in 2024). This rate is one of the highest in Latin America and has a high impact on lower-income citizens, since the purchase of 50 monthly tickets is equivalent to 15% of the local monthly minimum wage.

The article discusses a study which explores whether exposure to captive wild animals can be a source of zoonotic infection. The study was conducted with a collection of exotic fowl at a zoo in Bogotá, Colombia and the presence of Mycobacterium avium-II was related to the death of the birds. It showed that Mycobacterium gordonate-IV was disseminated in all organs of the birds and emphasized the importance of the establishment of handling norms to lessen the risk of zoonotic transmission.
