Specific lower back pain is a concern for Omicron variant BA.2.75
Even though the particular reason for the body pains have to be ruled out but scientists say that lower back pain is associated with the concerned symptom of omicron BA.4 and BA.5 variants. Apart from lower back ache, one should watch for other symptoms like cough, blocked nose, runny nose, nasal congestion and sore throat. A sub variant of Omicron known as BA.2.75 called Centaurus is been in circulation from May 2022 onwards which is also causing body pains and other above mentioned symptoms. But these variants and sub variants are not that much of strength but are contagious, so WHO still insists on wearing mask, have personal hygiene and also maintain social distance as prevention is better than cure.
