The UK based daily newspaper “The Mirror” said that there are two key symptoms that might indicate that a person could have “Stealth Omicron” before a positive PCR test.

The paper added that as the danger of the omicron variant started to lessen, a new “stealth omicron” also known as “BA.2” began to emerge, as some cases were recorded in December 2021.

Despite the fact BA.2 is still being researched by experts, a report from the World Health Organization (WHO) indicated that the BA.2 variant differs from the previous mutations due to its “cellular spike protein structure.”

One of the main symptoms is dizziness, which could continue for days, and if it gets more intense, the person must see a doctor, advised the NHS.

Fatigue is another symptom that appears early on, along with a sore throat, a runny nose and constant sneezing; these symptoms are shared between the Omicron variant and the BA.2 variant.

Skin rash, back pain and night sweats are lesser occurring symptoms.
