Today, some of the production chains reopened under the motto of the new normal. This leads to a gradual return of employees to offices and factories, which a greater mobility and use of public transport.

The Metro will again be one of the most popular transportation systems. In 2019, the National Autonomous University of Mexico (UNAM) and Autonomous Metropolitan University (UAM) carried out a health study in the metro facilities. The result showed that there are more than 50,000 bacteria in the facilities, Most of them concerned skin problems.

According to Luis David Alcaraz, bacteria that are incubated on trains can cause various types of acne. However, the focus of infection is not new and does not pose a serious health risk.

He mentioned: “Not all microbes are pathogens”. He also made that clear The main focus is on the site and not on the trains.

Thanks to the studies derived from the contingency of COVID-19, we can now be aware of the precautions and hygiene measures that we have to take when traveling on the train network. Among them are:

  • Use of antibacterial gel for after touching pipes and seats of the Metro Collective Transportation System.
  • Avoid eating anything and drinks in the facilities.
  • Do not sit on the floor of the platforms and trolleys.
  • Avoid eating foods that are made in the vicinity of the facilities.
  • Constant washing of hands and face.
