While a 7-year-old boy tested positive for Omicron in West Bengal, Tamil Nadu is likely to record its first case as six persons have been hospitalized with the suspicion of the Omicron variant.

Though Tamil Nadu hasn't reported the Omicron cases, the government is tightening up the containment measures as the variant has been making its move to several states. 

Though the variant is spreading rapidly, the experts say that it is not posing a severe threat as fatalities caused by Omicron remain low and the infection only leads to mild symptoms. 

Tamil Nadu Health Minister Ma Subramanian has said that the vaccination is mandatory for students above 18 years of age to attend the classes physically.

So far, four states - Karnataka (2 cases), Gujarat (1 case), Rajasthan (9 cases), and Maharashtra (8 cases) and the national capital region (1 case) had reported the Omicron cases. 

A micro-containment zone has been created where the Omicron infected man is staying and the officials are tracing and testing his contacts.

As the scientific world is currently researching the variant and the efficacies of the vaccines in beating it, let's go for a comparison between Delta and Omicron. 

It has infected over 380 people in 30 countries so far including India, with two Omicron cases that were detected on Thursday in Karnataka. 

India has also been staying alert over the outbreak and on Thursday, the country has reported the cases of Omicron for the first time. 

The health minister and Radhakrishnan had inspected screening facilities installed at the Madurai airport following the international outbreak of the new Covid-19 variant, Omicron.
