What is Delta Variant of Coronavirus

Within a week, among the confirmed cases of COVID-19 infection in Germany, the proportion of variant Delta strains almost doubled; the situation in the UK is worrisome. What's more troublesome is that the mutant strains are cleverly disguised.

What is the Delta Variant of Coronavirus?

According to the CDC, the Delta version, sometimes called B.1.617.2, may readily spread. The strain contains spike protein mutations which make it easier for human cells to get infected. This means that if people catch the virus and disseminate it more easily to others it might be more infectious. Now it’s the main strain in the United States.

Indeed, according to the Washington Post, experts indicated that the Delta form is around 50 per cent more infectious than the U.K. Alpha type. Alpha, also known as B.1.1.7, was already 50% more infectious than China’s first coronavirus in 2019.

Public health specialists consider that, in comparison with one or two other individuals through the first strain of Yale Medicine, an average person infected with Delta spreads to three or four additional people. Although investigations continue to take place, the Delta version can also avoid protection against vaccinations and some COVID 19 therapies.

How dangerous is the new crown mutant strain Delta?

(Deutsche Welle Chinese website) According to the latest data provided by the Robert Koch Institute (RKI), the more infectious and potentially more dangerous variant of the new crown strain delta has accounted for 6.2% of all confirmed cases in Germany. 

 Although this means that it is still  "rare" in this country , it has almost doubled compared with last week (3.7%) . 

Experts pointed out that the spread of the mutant strain may accelerate. In the United Kingdom, this mutant strain first discovered in India has caused a one-month postponement of the easing of the epidemic prevention plan originally scheduled to be launched next week. The background: In early May, the average infection rate per 100,000 population in the United Kingdom was still lower than 7 days. 20. Since then, it has risen sharply. At present, it has far exceeded 70. 

 Britain is an example  

  In the past 7 days, the new infections in the UK have highlighted the current spread of the Delta variant virus: 55,216 cases were reported from June 10 to 16, an increase of nearly one-third compared to the previous week. Experts pointed out that there are still comparable numbers of unreported infections. In addition, compared with the previous week, the number of people admitted to the hospital even increased by 40%.

Karl Lauterbach, an expert on health issues of the German Social Democratic Party, predicts that the number of people infected with the Delta strain will increase.  

Lauterbach, an expert on health issues of the Social Democratic Party, predicts that once autumn comes, the Delta mutant strain will again cause more infections in Germany. The medical-born politician told the media that a new Oxford University study confirmed that the seasonality of the mutant strain is significantly higher than originally assumed, which means that the risk of infection in summer will be much lower.   

Two vaccinations can provide effective protection    

However, he emphasized that this variant has three major problems: it is more contagious, easily leads to a more serious disease course, and has partial resistance to vaccines, especially if it is only vaccinated once. The Social Democratic Party person stated that he hopes that by then a sufficient number of people will have been vaccinated twice so that there will be no outbreak of the epidemic. 

According to the data analysis results provided by the British health authorities , people who have completed the BioNTech /Pfizer or AstraZeneca vaccination will basically not have a serious disease course, and the effectiveness is as high as the Alpha mutant strain. Compared with those who have not been vaccinated, the risk of hospitalization Reduce by more than 90%.  

People who received only one dose of the vaccine received significantly less protection. Especially AstraZeneca's vaccine. Originally, it should have been able to provide strong protection after the first vaccination, but the evaluation results showed that the protective effect after the first vaccination was significantly lower. 

Have different symptoms 

The Delta mutant strain is considered dangerous because the symptoms it causes are clearly different from previously known variants of the new coronavirus. Those infected will have headaches, runny noses, and sore throats. In addition, as reported by the relevant infected person to the British New Coronary Symptom Monitoring App, although fever is also a symptom, there is no loss of smell and taste.

An expert from King's College London who analyzed the results of related studies pointed out that this means that in some young people, the new crown COVID-19 is more like a common cold.

How can You Remain Safe?

While the Delta variety is now a modest problem in the World, being vaccinated as soon as feasible is extremely crucial. Full immunisation is efficient in preventing double mutation.

Note that all safety measures must be followed with complacency even after immunizations.

Fitting nose and mouth masks should be used in public at all times. If you can, dual mask. Use hand sanitisers and hand washers regularly.

Rest assured of social distance and not going to busy areas, if needed. Do not use cash; go as far as feasible for digital payments. Don’t eat or drink publicly, as your mask will need to be removed.
