The coronavirus BA.2 subvariant of the coronavirus’ omicron variant, sometimes called as a “stealth” subvariant, has been found in several patients in China. It is published that this stealth subvariant of omicron is the biggest one in two years for the Eastern countries of Asia.
It should be noted that the stealth variant of Omicron, Covid19 does not have the same missing target gene. An infection with BA.2 or stealth can be detected by Covid home tests kits, however they cannot indicate which variant is major responsible for the infection. Currently surge in the stealth sub-variant of omicron follows the initial spread of the BA.1 omicron variant of COVID-19, which was first identified in southern Countries of Africa in late November 2021 and quickly spread worldwide.
A recent laboratory study of the stealth sub-variant advised that its rapid increase is probably due to it being more transmissible than BA.1. Other preliminary studies have also recommended that stealth can readily overcome immunity from vaccination and previous infection with earlier variants, however it is not much better than BA.1 at doing so.

Fatigue and Dizziness are common everyday symptoms, one must keep an eye out if they continue to persist. If these symptoms bother you for a week or more, then one should consult a doctor.
