What is Delta Variant?

Updated On Dec 20, 2021

The Delta variant is one of the most worrying coronavirus variants currently due to its highly contagious nature. Studies suggested about the beginning of the year, that this highly contagious new variant is emerging and might lead to severe infections. To prevent it from spreading too much, global vaccination is required. The Delta variant is already leading to a rise in the number of COVID cases, especially in Europe. Here is all you need to know about this variant. 

What is Delta Variant?

Delta Variant: What is Known till Now

According to UNICEF, the WHO has stated the Delta variant one of concern. This is primarily because it has more transmissibility than most other variants before it and is also capable of causing severe COVID infections. This can not only cause complications in the person who has been affected by the variant but also to those to whom it spreads as it does so very easily and at a rapid rate. Rapid transmission is also of concern because it can easily mutate in that case. The more a certain virus can spread, the more are its chances of incorporating changes amongst itself. The Delta variant can spread twice as fast as the variants before it, making it important to stop the spread. 

Do the Vaccines Work Against the Delta Variant?

The various vaccines which have been approved by WHO against COVID are effective. The COVID-19 vaccines that are surrently being administered, are highly effective at preventing severe illness and death. This also extends to the Delta variant and now, the omicron variant as well. However, it is crucial to remember that no vaccine is 100% effective. It protects most people from getting infected. However, there might be people who get infected by the coronavirus even after getting the vaccine. However, the severity of the infection, in that case, is severely low. Whether or not you are fully vaccinated, you must be careful of any COVI-19 like symptoms and immediately get it attended by a doctor to avoid complications later, if they arise. COVID vaccines are now approved and available in most countries, which is why everyone must get them as soon as possible. In case the approved vaccine in your region needs two doses, such as the Covaxin and Covishield in India, it is important to take both of them for the vaccine to work most effectively.

Is the Delta Variant Harmful to Children?

There is nothing in particular that suggests that the delta variant is especially dangerous for children. Since children under 18 years of age largely remain unvaccinated, it is important to take care to not expose them too much to the virus. Since the Delta variant is particularly infectious, it might affect unsuspecting children as well. Make sure that they stay on a healthy diet of balanced food and exercise and wear their masks to avoid falling sick.


Following the Delta variant, there is a new variant that is present already, called the omicron. To adequately protect oneself against any and all types of variants. Every variant poses the dangers of becoming more severe infections than its predecessors which is why it is important to stay alert to them. Right now, the best ways to protect oneself remains vaccination and following COVID protocols such as wearing masks, using sanitizers and such. Wearing a mask is one of the most crucial protective measures. However, it is important to wear a proper and approved mask, and not just any cloth mask, for proper protection.
