Routes of public transport and the situation of tuberculosis in Lima, Peru

Abstract

In order to determine the association between the number of formal urban public transport routes and the situation of tuberculosis (TB) in each district of Lima, a correlational analysis and linear regression model between the two variables was performed. Also determined were the number of public transport routes most likely to transmit TB, the areas of greatest activity of these routes and a mapping of these routes. There is a positive correlation between the number of formal routes through each district of Lima and the situation of tuberculosis; a percentage of the TB situation could be explained by the number of public transport routes. Of the 404 formal routes that run through Lima, 147 (36.4%) are routes of greater probability of transmission of TB. Public transport should be considered in the ongoing fight against TB.
