This blog post gives an overview of current knowledge about the Delta variant and what we need to do to prevent its spread.
As the COVID-19 pandemic continues, several variants of the SARS-CoV-2 virus have emerged. This is no surprise, and a very normal outcome of the constant and rapid mutation of viruses. One variant has been particularly successful – the Delta variant.
The Delta variant first emerged in India in late 2020.
Delta is now the predominant type of SARS-CoV-2 in the UK and is emerging in other parts of the world.
It is associated with a higher rate of transmission – the evidence suggests that the Delta variant is approximately twice as infectious as other variants, although the reasons for this are not well understood.
There is some evidence that the Delta variant causes more serious disease than other variants.
The vaccines currently available for COVID-19 are effective against the Delta variant.

Whilst we don’t understand some of the reasons behind the key characteristics of the Delta variant (that it's more transmissible and has a tendency towards more severe disease), we do know that the fundamental transmission routes for the virus have not changed. Like all SARS-CoV-2 variants, the main transmission routes are via respiratory particles, with contact transmission possible too. Therefore, to prevent the spread of the Delta variant, we should continue to practice the behaviours we have learnt in the last 18 months.
If everybody was vaccinated, the Delta variant wouldn’t spread.
Practicing good hand hygiene should now be second nature to us all to prevent the spread of COVID-19 and other infectious diseases.
In the UK, the law has now changed meaning that wearing of masks is a personal choice. Our advice is that masks should be worn when in enclosed indoor spaces, especially when ventilation is poor.
Improving physical distancing will help to prevent the spread of COVID-19. We should physically distance wherever possible.
The better ventilated an indoor space is, the lower the risk of COVID-19 spreading.
SARS-CoV-2 can contaminate surfaces. That's why, surfaces should be cleaned and disinfected regularly. Clinell Universal Wipes are effective against the SARS-CoV-2 virus.

Delta won’t be the last SARS-CoV-2 variant to emerge, but it has been the most ‘successful’ so far. With autumn almost upon us, we can expect the prevalence of COVID-19 to increase in line with seasonal trends. Therefore, it's never been more important to keep going with our COVID-19 prevention measures.
