Alert: Delta variant

In order to avoid the stigmatization of countries and cultures, the World Health Organization has decided to use the Greek alphabet to rename COVID-19 variants. One of them, the Delta variant, is still colloquially called “Indian” and worries the scientific community to a significant extent.

More contagious

According to Imperial College London, the Delta variant would be 60% more contagious than other mutations of the virus. It has caused infections in the UK to increase despite mass vaccination.

Who can contract the Delta variant?

People vaccinated with just one dose can become infected with this Delta variant, but those who have not received the immunization are even more likely to get it.

Vaccinated people can also get the Delta variant

Data collected in Great Britain show that those who are vaccinated (either with one or two doses) have extra protection and rarely get seriously ill. In fact, only 3.7% of Delta variant cases in the region involve fully vaccinated people.

Effectiveness of Pfizer

Analysis of the UK data suggests that a complete course of the Pfizer vaccine protects 83% against the Delta variant. A single dose of that specific vaccine protects 33%. Although its effectiveness against the Delta mutation is limited, especially compared to its 90% effectiveness against other variants, the vaccine is still a very strong barrier against the virus.

Higher levels of hospitalization

In the UK, the Delta variant has led to more severe cases of COVID-19, Imperial College researchers found. They estimate that an infected person's risk of hospitalization is 2.5 times greater with this variant of the coronavirus.

The unvaccinated population suffers the most

British scientific authorities observe that the cases of hospitalization are mainly of unvaccinated people (73%).

The importance of taking both doses

It is necessary to complete the vaccination - with both doses - to stop the circulation of this variant. In addition, social restrictions such as wearing masks and keeping a distance must continue.

A third dose?

Some scientists even suggest that a third dose of the vaccine will be necessary in the near future. This extra dose will be specifically aimed at repelling variants like the Delta mutation that are currently circulating.

Easing of restrictions may have to be undone

If due to the Delta variant there is a significant increase in cases, the expected 'return to normal' may have to be postponed in many countries.

Tragedy in india

Meanwhile, the pandemic is still raging in India. However, in recent weeks the contagion curve has finally dropped.

Isolated cases in the UK

Despite everything, there is no sense of panic in the UK and so far only isolated cases of the Delta variant have been found in other European countries.

Vaccines against the virus

At the moment, scientists trust vaccination as the most powerful weapon against the really dangerous expansion of the Delta variant.

Viruses adapt

Mutations like this Delta variant are the result of a process in which viruses adapt to improve themselves and survive. It's a common biological phenomenon.

When will COVID-19 be something like the flu?

The hope is that when we achieve group immunity, COVID-19 will lose its virulence and become one of the many forms of flu that we experience every year. These normal types of flu have limited numbers of casualties.

Keeping an eye on the Delta variant

The World Health Organization is monitoring the incidence of the Delta variant. At the same time, however, many countries believe that the pandemic is coming to an end because they see their cases decrease.
