What Are The Different Types Of Covid-19 Variants?

The Covid-19 pandemic caught the world off-guard and let’s just say we’ve learnt and done a lot of things that once seemed like a far-fetched reality. As the Covid-19 virus has been mutating, it’s also brought new sops, which means we too have had to evolve and understand the changes with every new variant.

At present, it’s the Delta variant that has taken the world as hostage with vaccines doing their bit to keep us safe and immune. But did you know that the Delta variant is just one of the many variants of the infection?

Now, mutation happens with all living organisms – humans and the virus alike. The viruses though mutate quickly and can get worse or stay neutral at the end of the process.

In this case, while some variants of the viruses aren’t too concerning, there have been other mutations that did more damage that we originally anticipated due to its high transmissible nature.

You’ve known about the Alpha, the first variant after the original Covid-19 infection, and since it has mutated into different types. So don’t be surprised if you soon hear about a new variant of Covid 19 out there.

As we move towards what could be an endemic, here’s a look at the different variants of Covid-19 and their current status.

At present, there are four known variants of concern and six variants of interest under Covid-19. All of these are on the watchlist of the World Health Organisation (WHO) as well as the US Centers for Disease Control (CDC).

While officials say there might be many more variants, these 10 odd variants of Covid-19 that the health officials actually worry about.

Interestingly, there’s also a third category that would be ‘variants of high consequence’ that sits above variants of concern.

This is the really scary list that you would never want. Fortunately, none of the Covid 19 variants have been classified in the category yet.

Variants of Concern

The WHO and CDC classify some Covid-19 variants as variants of concern. These are worse for diagnosis, treatments or vaccines, and are transmissible at a faster rate. In essence, these are more dangerous and people need to avoid them as much as possible.

1. Alpha

What You Should Know: It is 50 per cent more transmissible compared to the original Covid-19 virus. It may cause severe health complications. Convalescent therapy and vaccination may be minimally impacted.

First Identified In: UK, September 2020

Where It Is Now: It’s the second-most common variant but far less spread out than the Delta variant.

2. Beta

What You Should Know: The Beta variant is 50 per cent more transmissible than the original virus. One type of antibody treatment is significantly less effective against it. Convalescent therapy and vaccination are less effective against it.

First Identified In: South Africa, May 2020

Where It Is Now: Fewer cases have been currently reported.

3. Delta

What You Should Know: It’s easily the most popular among all variants at present and twice as transmissible. Antibody treatments and vaccination may be less effective against it.

First Identified In: India, October 2020

Where It Is Now: In several countries worldwide. It is responsible for a major number of new Covid cases.

4. Gamma

What You Should Know: One type of antibody treatment is significantly less effective against it, and convalescent therapy and vaccination are less effective against it.

First Identified In: Brazil, November 2020

Where It Is Now: One of the most common variant in Brazil and Chile.

1. Eta

What You Should Know: Antibody treatments, convalescent plasma therapy, and vaccination may be less effective against it.

First Identified In: UK and Nigeria, December 2020
