Omicron sub-variants such as body ache, fatigue, and low-grade fever. The symptoms usually last for five days, the UN body added.
According to the experts, the BA.2.75 sub-variant is more transmissible but hospitalisation and deaths are less. "BA.2.75 sub-variant has acquired more mutations in spike protein and other genes of the SARS-CoV-2," according to the Indian SARS-CoV-2 Genomics Consortium (INSACOG).
Some reports suggest that Omicron BA.2.75 can evade previously gained immunity and can re-infect those who have had Covid. However, it does not mean that getting vaccinated against Covid is pointless because even if there are breakthrough infections, immunisation helps prevent the progression of the disease to a more severe stage.
The most common symptoms for Omicron and its sub-variants are: runny nose, cough with phlegm, hoarse voice, sneezing, fatigue, muscle pains, dizziness, fever, body aches, loss of appetite, nausea, and diarrhoea.
