The 'stealth' variant is just as mild as the original version of the strain, officials at the (WHO) said Tuesday. BA.2, as it is officially named, picked up the 'stealth' moniker due to its ability to avoid detection through some sequencing processes. While it is believed to be more infectious than its predecessor, BA.1, officials are not worried about the strain causing yet another surge or causing more harm to people.
'Looking at other countries where BA.2 is now overtaking, we're not seeing any higher bumps in hospitalization than expected,' Dr Boris Pavlin, a member of the WHO's Response Team, said during a briefing.
'Vaccination is profoundly protective against severe disease, including for Omicron. BA.2 is rapidly replacing BA.1. Its impact is unlikely to be substantial, although more data are needed.'
