Prevent Dust Formation, COVID-19 RNA Stays Up to a Month

What does this COVID-19  study says?

A study was conducted in the rooms where COVID-19 patients were isolated to study the RNA of the virus. RNA is the part of the genetic material  found inside the virus. RNA can be considered as the heart of the virus. They studied and tested the dust found on the floors of the isolation wards where Covid-19 patients were staying. The study finds that covid-19 virus RNA can stay up to a month in dust.

Researchers Finds

They found genetic material from the SARS-CoV-2 virus , that causes COVID-19

  • 97% of the bulk dust samples and
  • 55% of the surface swabs

They collected dust and swabs of the isolation center, with the help of vacuum cleaner. Surprisingly, even after four weeks, RNA of the virus did not decay in the vacuum bags.

Can Covid-19 virus be transmitted via dust?

The scope of this study is not to study whether it gets transmitted via dust or not. So, if you find dust, it doesn’t mean the virus is transmitted via dust.

Takeaway from this Covid-19 study

Focus on Dust Monitoring and cleaning

It is important to focus on deep cleaning the space where the covid-19 patients stays or have stayed. Prior to cleaning, spray a chlorine-based disinfectant in the rooms and then deep clean the area. This will help prevent COVID-19 outbreak.

How To Prevent Dust in The House

Use Air Purifier

To trap dust particles of up to 0.3 microns in size, use air purifier with a True HEPA filter.

Remove clutter

Remove unnecessary clutter as it will prevent the dust to be collected at the area. Recycle or organize the clutter to keep the place tidy.

Keeping Dust Outside The House

Using air purifier is important to catch the free-floating dust particles. Don’t allow the outside shoes enter inside the home. Keep separate footwear especially for indoor. Another tip is to use the high quality door mats to collect the dirt and debris outside the place.

Use a HEPA Vacuum Cleaner

A standard vacuum cleaner fails to collect the dust with microscopic size. So, it is important to use a vacuum cleaner that has true HEPA filter. This will remove the ultrafine dust particles up to 0.3 microns in size.


Be careful even when you are visiting to hospitals, nursing homes or the places where Covid-19 outbreak is there. The duty is up to the cleaning and maintenance staff. If you have covid-19 patient at home isolated in a room then follow the above guideline to prevent the further outbreak apart from other safety measures.
