Omicron: is there a sign of the third wave?
The delta variant of coronavirus has been very dangerous for us worldwide, we have not yet come out of its effect that another new variant has come which is very dangerous and very soon it is transferred from one person to another. Being said to be more dangerous than the delta variant.
The new variant of coronavirus is called omicron, yes it is more dangerous than delta variant. In the second wave of coronavirus people all over the world faced delta virus due to what lot of people lost their lives, the heavily destruction of mankind.Early indications are that this new strain of coronavirus is possibly even more transmissible than the highly infectious Delta variant, and that current vaccines may be less effective against it.
What is update on Omicron?
New variants continue to emerge as SARS-CoV-2 spreads, and the significance of each mutation becomes known after a period of time. But health authorities worldwide need to keep a constant watch to identify which ones are more important than others. It was as part of such an exercise that the NGS-SA detected B.1.1.529.
From what is known currently, B.1.1.529 has multiple spike protein mutations, and preliminary analysis suggests it is highly infectious. South Africa has reported a four-fold increase in new cases over the last two weeks, coinciding with the emergence of B.1.1.529.

It has said that some of the mutations are well characterised with a known phenotypic impact, affecting transmissibility and immune evasion. Some of these mutations have already been detected in the Alpha and Delta variants. But many other mutations, the NGS-SA said, have been “rarely observed until now and not well characterised”. So, the full significance of these mutations remain uncertain at this point. “More investigations are underway to determine the possible impact of these mutations on the capacity of the virus to transmit more efficiently, to impact vaccine effectiveness and evade immune response, and/or to cause more severe or milder disease,” the Africa Centers for Disease Control (CDC) has said.
What is the WHO’s assessment?
The WHO said that its technical advisory group met to review the new variant and designated it as a variant of concern. This effectively means that Omicron has been demonstrated to be associated with one or more of the following changes: increase in transmissibility; and decrease in the effectiveness of diagnostics, vaccines, therapeutics.
The National Institute for Communicable Diseases (NICD) of South Africa has said that currently, “no unusual symptoms” have been reported following infection with the B.1.1.529 variant. It has highlighted the fact that, as with other infectious variants such as Delta, some individuals are asymptomatic.
All the expert bodies have stressed that vaccination remains critical, especially to protect groups at high risk of hospitalisation and death. Real-time data have shown that high vaccination rates also significantly reduce the strain on health systems.
Precautions are better than covid 19
The emergence of the new variant shows once again that the pandemic is far from over — and Covid-appropriate behaviour is critical for breaking the chain of transmission: masking, social distancing, good ventilation in all shared spaces, and washing or sanitising hands and surfaces regularly.
Stay safe stay healthy!!
