According to The Star, Omicron variant is currently known to be significantly more contagious than previous Covid-19 variants, but it appears to induce a less severe sickness than its predecessors, a month after it was first found in southern Africa.

What isn't apparent is how the new variety will alter the pandemic's course.

When comparing Omicron to the Delta variant, the president of the French government's scientific advisory council, Jean-Francois Delfraissy, stated that Omicron's transmission is substantially higher, but its severity is likely weaker.

"However, we have no idea how much weaker," he explained.

Omicron is spreading faster than any other variety before it, with instances doubling every two to three days in some nations.

How many hospitalizations?

One major question is whether Omicron would result in a rise in hospitalizations, putting national health systems under strain.

"Even if Omicron causes less severe disease," World Health Organization chief Tedros Adhanom Ghebreyesus said last week, "the sheer volume of cases could overwhelm unprepared health systems once again."

Hospitalizations appear to be low in South Africa, but experts say one cause could be the population's relative young compared to Europe.

Are vaccines still effective?

Antibody levels in blood samples from patients vaccinated with Pfizer-BioNTech and Moderna jabs diminish when exposed to Omicron, according to recent lab testing.

The decrease is considerably more pronounced in individuals who were vaccinated with AstraZeneca or Sinovac, a Chinese vaccine approved in more than 50 countries.

Both Pfizer and Moderna have announced positive results from recent experiments, indicating that a booster boosts antibodies.

However, no one knows how long the booster will work.
