Scientific research continues to make significant progress in the fight against the pandemic. In the UK, a team from the Healthcare Technologies Institute at the University of Birmingham worked to create an aerosol capable of providing protection against the coronavirus and test results have demonstrated the effectiveness of this tool.
The aerosol was created using existing compounds commonly used in medical devices, food products and drugs. The study carried out by scientists from this British institution details cell culture experiments designed to test the ability of the solution to inhibit infection, as explained by Medical Writing.
Prevents virus for up to 48 hours
The researchers found that the viral cell cultures inhibited the infection for up to 48 hours after being treated with the solution. “This spray is made from readily available products that are already used in food and medical products and we have deliberately incorporated these conditions into our design process. Means that, With the right partners, we could start mass production in a few weeks ”. said lead author of the study, Richard Moakes.
The spray is composed of two polysaccharide polymers. One of them is an antiviral agent called carrageenan, element commonly used in foods as a thickener, and the other is a solution called gellan. The latter is a component that has the ability to spray in droplets inside the nose, where it is able to remain stable without slipping.
“Although our noses filter thousands of gallons of air every day, there is not much protection against infection and most airborne viruses are transmitted through the nasal passages. The spray that we have formulated provides this protection, but it can also prevent the virus from spreading from person to person. “ says another of the study’s authors, Liam Grover.
Easy to remove
According to the researchers, The aerosol is able to capture the virus by coating it inside the nasal cavity, allowing it to be removed simply by swallowing or blowing your nose. In addition, it prevents the body from absorbing the virus thanks to its encapsulation in the viscous layer of the aerosol, it can therefore also be removed with a tissue.
In this way, The viral load in the body and the possibility of passing the virus on to other people is reduced even if you sneeze or cough in an enclosed space. For this reason, scientists consider that its use will be particularly recommended in places such as airplanes, trains and even in schools, since it could prevent further infections.
However, they point out that the the aerosol is “a second layer of protection”, which does not imply that measures such as the use of masks and hand hygiene are no longer applied, factors that “will continue to be vital in preventing the spread of the virus,” says Richard Moakes.
