Omicron Beats Delta

Experts believe that the Omicron Variant of COVID-19 will be more transmissible that Delta. The World Health Organization (WHO) reported that 38 countries across the world have reported cases of the highly mutated omicron Covid-19 variant so far.

The virus spike proteins have  32 mutations which make it easier for the virus to spread and infect humans. For comparison, Delta had 9 mutations. The Omicron variant might also evade COVID-19 vaccines, but it could take some time to see if that’s true or not. The Omicron variant may also cause more re-infections.

More children are being admitted into hospitals with COVID infections in South Africa where the variant was first reported. Last month in South Africa, 74% of genomes sequenced were Omicron. Within two weeks, Omicron has replaced Delta in South Africa. 56 countries have imposed travel bans but the virus has already spread world wide. Thousands of people have flown into the United States from South Africa and other infected countries since the variant was first reported and when the flight restrictions finally began. Omicron can reinfect people who have had COVID-19. Since it can reinfect people the pool of potential hosts makes for exponential growth in infections. Omicron will become the main variant in the world.

At the moment, the only data scientists have to estimate omicron’s transmissibility comes largely from the cluster of cases at a university in Pretoria, South Africa. The rapid rise in cases there could be due, in part, to a superspreading event.With only 4% of the population vaccinated, thousands of people took to the streets to protest in a “Superspreader March.” It was a “March to Save Lives” but may have instead been the perfect way to spread the new variant.

Cases of Omicron in America have been reported in 5 states so far but it is likely fare more wide spread. The only reason we don’t know more, is that the United States has a very poor record of genomic analysis compared to other countries. The first case discovered in America had been fully vaccinated but had not gotten a booster yet.

Basic health measure that have been promoted since the start off the pandemic still work. Wear a good quality mask, social distance and wash your hands often.

The good news is the early cases have been mild so far. However cases usually get worse in the second and third week of infection, so we will see how deadly the virus  mutation is soon. If it turns out that it produces only mild cases that do not require hospitalization, then that could be very good news. Time will tell.
