Omicron, the new strain of coronavirus with 32 mutations found in South Africa could replace the Delta strain and become the most dominant one across the world. Adrian Puren, the Acting CEO of South African National Instititue for Contagious Diseases said so in an interview with Reuters on Tuesday.

"We thought what will outcompete Delta? That has always been the question, in terms of transmissibility at least, ... perhaps this particular variant is the variant", the scientist said.

According to him, if Omicron proves to be more contagious than Delta, it might lead to the rapid outbreak of incidence and create pressure on hospitals. 

Puren added that the scientists have four weeks to find out how Omicron evades protective maneuvers of the immune system created by vaccines or previous infection; they also need to find out whether it causes more serious clinical symptoms than other kinds of the virus.

The unofficial reports of doctors who treated patients with Covid-19 in South Africa prove that Omicron causes light symptoms, including dry cough, fever and sweatiness in the night time. However, experts warn people not to make any certain conclusions in this regard.

Puren says it's too soon to tell whether Omicron replaces Delta in South Africa because local scientists have just investigated 87 genetic sequences of the new strain.
