Scientists Research 'Stealth Omicron' COVID Strain

The video discusses the rapid spread of the Omicron variant, focusing on its two sub-variants: BA.1 and BA.2, also known as stealth Omicron. Stealth Omicron is harder to detect with current tests, leading to delays in identification. This poses challenges for public health, as it affects treatment and understanding of the virus's spread. Scientists are using viral surveillance techniques to track these variants, but the stealth variant's lack of a specific test signature complicates detection. Current findings suggest stealth Omicron spreads slower than BA.1, but more research is needed.
