Inhalation is the most influential method of transmission of the coronavirus. The SARS-CoV-2 virus can be transmitted by contact with surfaces (touching surfaces where viruses may have accumulated and then touching our mouths or our eyes with our hands) or through drops of saliva or respiratory fluid (landing on our eyes, nostrils and mouth). However, these coronavirus transmission causes are less influential than aerosols (droplets that are so small that they can remain floating in the air for a long time), which infect us when upon their inhalation, the main transmission route for viruses.
Important points about coronavirus transmission:
- It is easier to get infected to infect many more people in indoor areas.
- Talking loudly and shouting increases contagion chances: there has been less contagion in libraries and cinemas as people are more silent there (remember a football occasion cited as the main catalyst of the spread of coronavirus in Italy back in 2020 March).
- We get infected by breathing the air exhaled by others so need to ensure that all the rooms used by different occupants need to be well-ventilated
- All public spaces can have a CO2 meter to indicated how many times they were aired and it might be convenient to use air filters.
- It is advisable to arrange meetings outdoors with complying with social distancing and mask rules.
- Masks do not last infinitely. Actually, it would be preferable to replace them as certain types can last only for a few hours. Therefore, you have to pay attention to the quality of the masks and ensure that they are well-adjusted.
- Decent contact tracing, plenty of tests and showing respect to quarantine and isolation rules are also critical as corona virus does not infect any longer once you remove those affected from circulation.
- These measures to prevent transmission are not as costly as confinement, which is practices in the form of limited movement freedom, lockdowns and curfews.
