COVID-19 is airborne.

How can you protect yourself and your loved ones?


We’ve already heard it so many times. Wear a mask. Sanitize or wash hands. Socially distance. Avoid crowds. So much so that sometimes we tune out health rules and regulations. But with the recent spike in COVID-19 patients, with more patients hospitalized and more young people at that, we need to realign and come back to what we’ve always known. COVID-19 is not going anywhere and a 3rd wave has already bulleted its way onto our shores, full throttle.

As always, oDoc is here to provide you with the latest information on COVID-19 and the best protocols for keeping you and your loved ones safe.

COVID-19 aerosols droplets

COVID-19 is airborne. What does that mean?

COVID-19 is spread through the air by respiratory droplets and aerosols. Aerosols play a significant role in increasing the infectiousness of the virus. They are tiny droplets that can remain suspended in the air for hours with poor ventilation. Bigger respiratory droplets fall to the ground in seconds and reduce the chance of getting inhaled by a non-infected person.

Let’s say you go to your gym. Maybe you’re going at non-peak hours, where there are not many people around. You may think that you could unmask and use whatever equipment you please. But if a COVID-19 infected person used the gym a few hours ago, their infected aerosols will still remain suspended in the air, especially if the space is poorly ventilated, i.e. with no open windows or fans to circulate air.

You can easily breathe in those aerosols and become infected yourself. So even if there is no one else around you in an indoor space at a specific moment in time, you can still get COVID-19 by infected people who were in that space just a few hours ago.

Things to keep strictly in mind, especially when visiting enclosed, indoor spaces:

Double mask! Make sure the fit is secure with no space for respiratory leakage. If you’re wearing a KN95 or N95, you don’t need to double mask.

Wear your mask/masks whenever you’re out of your home and not only when you’re near another person as infected aerosols can still remain in the air
social distancing
If possible, meet others outdoors where any infectious particles will be rapidly diffused. Wash your hands with soap or use hand sanitizer frequently. Maintain 6 feet physical distancing

Avoid entering indoor spaces that include others who are not from your household. If you absolutely need to visit an indoors place, make sure the space is properly ventilated with multiple open windows for cross ventilation and minimize the time spent in this space. The longer time you spend indoors, the higher chance of infection!
