People infected with Omicron are 80% less likely to end up in the hospital, says NICD




NICD is a public health institute in South Africa. They provide research data about microbiology, epidemiology, virology, and more. 


Professor Cheryl Cohen is the head of the NICD’s Centre for Respiratory Diseases and Meningitis. 

She said, “Compellingly, together our data suggest a positive story of a reduced severity of Omicron compared to other variants.” 

She conducted an early evaluation of the severity of Omicron in South Africa with her colleagues.

What the study shows.

From October 1st to November 30th, 2021, they compared the severity of cases between Omicron infected individuals and Non-Omicron infected individuals. 

Then in the third wave, they compared severity between Omicron and Delta variants for their second part of the analysis. 

Results from their first comparison show that individuals who are infected by Omicron are 80% less likely to be admitted to the hospital.

In the second part of their analysis, the result indicated that Omicron is 70% less severe than Delta infections in the previous wave. 


“Both datasets point to less severity when looked at on an individual level. 

It’s very encouraging data that points strongly to a substantially lower severity in the Omicron wave,” 

said Cohen. 

“What that means is that people included were allowed three whole weeks for their outcomes to be assessed. The data seems to be robust and there’s no suggestion that this pattern is going to disappear,”

 she added.


There are some factors like South Africa’s high levels of natural immunity that are influencing the results of their research and the severity of Omicron. 

“It could include the level of prior immunity from people who have already gotten vaccinated or who had the natural infection, or it could also be due to the intrinsically lower virulence of Omicron, but we need more studies to be able to unpack these things,”

 Cohen said. 

“We can’t tell from this data how much is as a result of vaccination and how much is from previous infection and intrinsic reduced virulence of the virus,

But in South Africa, this is the epidemiology: Omicron is behaving in a way that is less severe,” 

she added. 



These findings of NICD are giving hope to humanity.

So let’s hope for the best.

Let’s continue to wear masks and take the necessary precautions as we did so that we can say goodbye to the Coronavirus soon.
