**Abstract**

The spread of the COVID-19 pandemic, caused by the SARS-CoV-2 virus occurs by the dissemination of viral infections, forcing the need for actions to control the virus. COVID-19 caused a pandemic that impacts the health system in biomedical and epidemiological order on a global. One of the measures taken by governors to contain the dissemination of the virus was the closure of airports, ports, and land borders, keeping only essential repatriation flights. The concern about agglomeration of people in public spaces causes the need for ventilation control in order to reduce the contagion and maintain hygiene in airports and planes. The sum of these factors brought, as a consequence, a resumption of decisions about how to adopt postures to control the contagion. Based on this analysis it turns out that ventilation is the fundamental factor to control the spread of the COVID-19 pandemic. In the civil aviation sector for passengers transport on planes and airports, the following related aspects are presented: (1) determining the air conditioning system coefficients in commercial airplanes for passenger transport using CFD (Computational Fluid Dynamics) simulations to check airflow; (2) present new hygiene technologies for planes and airports.
