Organization [WHO], 2022). Among the reasons that stand
out: (1) the virus is not in contact with the disinfectant long
enough, (2) the respiratory system, which is the main part of
the body involved in its transmission, cannot be sprayed, (3)
it gives a false sense of security, (4) it is harmful to the
environment, (5) the chemicals can cause irritation to the
digestive, respiratory and skin systems, among others
(Ghafoor et al., 2021; Goh et al., 2021).
The same reasons apply to the use of disinfection tunnels,
which can also cause a dispersion of the virus due to the
difficult control in the way they spray (Gray & Van Niekerk,
2020). In addition to the investment in the purchase and
transportation, the costs of installation, maintenance and the
use of infrared detectors that are activated when detecting a
person passing through them are added. The cost-benefit
balance does not justify the use of these spray systems, since
there are more economical, simple and effective strategies
(Biswal et al., 2020; Hirose et al., 2020; Jameleddine
Chtioui et al., 2020).
In Honduras, it has been common for shopping centers
and offices to spray disinfectants on the skin and clothes, as
well as the use of disinfectant mats. At the beginning of the
pandemic, the practice of spraying car tires and tunnels for
spraying cars were also installed, until the cost and scientific
evidence discouraged it. Practices associated with a lot of
anxiety due to the fear of being infected.
The evidence has made it clear that SARS-CoV-2 spreads
by air and that it can even remain suspended in the air for
several hours. Therefore, spending resources on disinfecting
surfaces that do not have the effect of dispersing the virus is
inappropriate. The Centers for Disease Control and
Prevention (CDC) from the United States, recommends
disinfecting only surfaces that are in contact with bodily
secretions and high-touch surfaces, such as doorknobs, light
switches, cell phones, keyboards, remote control and touch
screens (CDC, 2021).
It is necessary to inform and to raise awareness among
citizens so that they refrain from using practices that have
no evidence of being useful to combat the spread of SARS-
CoV-2 and that may actually be harmful to their health and
the environment. The evidence indicates that the practices
that do work to prevent COVID-19 are physical distancing,
hand hygiene (especially with soap and water), the use of a
mask, vaccination, adequate ventilation of spaces (safe air)
and case isolation (Organización Mundial de la Salud
[OMS], 2020).
