Omicron is a variant of global concern due to its high transmissibility. Emerging research has revealed that the Omicron variant causes less damage to the lungs and less severe disease when compared to other variants.

"It's a well known fact that myalgias are commonly seen in viral infections. Covid is not an exception but we are seeing more cases of back pain with Omicron even after recovery which patients label as weakness," Dr. Arun Chowdary Kotaru, Consultant, Respiratory/ Pulmonology and Sleep Medicine, Artemis Hospital, told IANS.

However, since data on Omicron is limited and gene sequencing is costly, the reason is "difficult to explain", Kotaru said.

First detected in South Africa and Botswana in late November, Omicron has been discovered in more than 100 countries and across all seven continents, as per the open access data sharing platform GISAID.

India on Wednesday registered 4,033 Omicron cases from 27 states. Of these, 1,552 have been discharged from hospitals.

Meanwhile, scientists at Department of Biotechnology's Indian SARS-CoV-2 Genomics Consortium (INSACOG) in India said that the highly transmissible Omicron with three sub-variants - BA.1, BA.2 and BA.3 - is likely replacing the previously dominant Delta strain in India, pushing the daily tally of Covid cases in the country.
