Lately, a report published in the medical journal Lancet mentioned that SARS-CoV-2 virus that is
responsible for COVID-19, is an airborne pathogen which means that this disease could primarily be
transmitting through air. This has been an alarming finding as when a COVID positive person coughs or
sneezes, they release particles (droplets) containing the virus. While larger droplets fall to the ground,
smaller droplets comprising the virus can remain suspended in the air. Further, if someone breathes in
the same air, they can get infected with the virus.
In the current scenario, the role of ventilation is indispensable. Ventilation plays a crucial factor in
preventing the virus from spreading indoors. Poor ventilation can build up the virus in the room
consequently spreading it to more people. While people can resort to natural ventilation methods like
opening doors and windows, it is important to ensure that the air is getting circulated continuously.
Below are the ways by which you can improve ventilation in your home:
1. Bring fresh air into your home whenever possible. Open the doors and windows as much as
you can to bring in fresh air. The inflow of fresh outdoor air into your home will help to keep
stale air from amassing inside.
2. Turn on exhaust fans in your kitchen and bathroom whenever possible. This can improve air
flow and keep contaminated air from being concentrated in one place.
3. Always keep ceiling fans on to help improve air flow in an occupied room.
4. With the summer heat getting intense, cooling your house can be a challenge with the
windows and doors kept open. Use a cooling solution like an air cooler as they provide
adequate cooling even with open doors and windows. Air coolers also come with multistage
air purification filters that can further help in improving the indoor air quality.
