Abstract

The pandemic generated by COVID 19 is the defining global health crisis of our
time and the greatest challenge  the world  has faced  since World War II. It is transmitted predominantly by aerosolization, droplet particles, respiratory secretions and by contaminated objects or surfaces. One of the most used means of locomotion in the world is public transportation, but   due to the proximity of people, overcrowding, inadequate ventilation and the  recirculation of contaminated air, viral transmission is practically unavoidable. In this
work we analyzed the contamination of passengers in four types of minibuses, Midiobuses, Basic and Trolleybuses, where we calculated the percentage of infected in normal transport conditions, with the reduction of seats and the distance between occupants and showed that where preventive measures were applied there was less contamination.
