A. The same as the old SARS-COV-2 variants. The new variants are more contagious (as expected since evolution selects for such variants) and thus increase transmission rates up to 70%, which will result in more positive tests and cases, but not any more lethal. The latest UK variant, dubbed VUI-202012/01, is believed to be more contagious but not more lethal than other strains. Look for emergency warning signs for COVID-19. If someone is showing any of these signs, seek emergency medical care immediately: We’ve been living in a Covid world for more than 18 months now. At the outset of the pandemic, government agencies and health authorities scrambled to inform people on how to identify symptoms of the virus. Emerging data suggest people infected with the Delta variant — the variant behind most of Australia’s current cases and highly prevalent around the world — are experiencing symptoms different to those we commonly associated with Covid earlier in the pandemic.
