Open windows reduce chances of contagion of COVID-19

The fight against COVID-19 has already been going on for more than a year and it has not yet been possible to fully control the global pandemic. Specialists work tirelessly from different perspectives to find ways to prevent further infections and to eradicate this virus. While it is true that hopes for vaccines increase every day; you need to do everything you can to prevent this virus from spreading further; so all necessary measures must be taken.

Air as a priority measure to avoid contagion

The results that have yielded a variety of studies allow many specialists to affirm that air circulation is a very beneficial factor in reducing the chances of contagion of COVID-19. It has already been proven that the probability of contagion is much higher when it comes to closed places compared to open spaces such as parks, streets, squares, among others.

This statement can be supported based on various investigations; one of which analyzed more than 50 studies with a sum of more than 77,000 people. Research results ensure that 16.6% of people living with a confirmed case of COVID-19 are infected; a higher percentage when compared to other types of viruses such as SARS and MERS.

Likewise, it was announced that the chances of contagion are much higher when it is a symptomatic case and lower when the positive case is asymptomatic. Other data show that adults are more likely than children and that they are much more likely to get it from their partner than from any other family member they live with.

All the data collected suggest that being in a closed space, but properly ventilated; contagion is much less likely, as long as other measures such as use of masks, hand washing and social distancing.

How to reduce the chances of contagion indoors?

Considering that closed spaces imply a higher rate of contagion, it is essential that measures are taken into account to reduce the chances of infection. It is essential that people who are in closed spaces follow the measures that we all already know: hand washing, social distancing and correct use of the mask. Ventilation should be added to these measures to improve the chances of maintaining health.

Some of the strategies proposed by the WHO to improve ventilation in closed areas are the following:

  • Privilege natural ventilation, opening windows and other fresh air intakes.
  • If you have a mechanical air system, increase the percentage of outside air; even, if possible, 100%.
  • Inspect and constantly change artificial ventilation filters.
  • Run the ventilation system at least 2 hours before the space is occupied and for an additional 2 hours after the area has been vacated.

And you, what measures do you take to protect yourself from Covid-19?
