Risk of emergence of more dangerous variant Omicron

Professor Chris Whitty said that the world could suffer a wave of COVID-19 epidemic new in the next 2 years due to the appearance of a variant with more unpredictable consequences Omicron. He affirmed that there is a long way to go until the world can get rid of the COVID-19 pandemic and this will be an endemic and life-threatening disease similar to the flu.

At the England Local Government Association public health conference, Mr Whitty said it was too early to think that the COVID-19 pandemic had reached a steady state and he urged the world to be cautious with the pandemic. this pandemic. He also thinks that the consequences related to Omicron are not light, as many experts have previously said. He stressed, the world could see the pandemic ending with a more devastating variant than Omicron.

In fact, the world has recorded more variants of the SARS-CoV-2 virus. Most recently, the World Health Organization confirmed the existence of a hybrid variant between Omicron and Delta. Last week, Israel also discovered a new hybrid variant between two sub-variants of Omicron BA.1 and BA.2. Fortunately, several studies are underway that show no serious contagion reported.

Meanwhile, WHO’s top health expert Maria Van Kerkhove emphasized that at the current epidemic stage, testing and genetic sequencing need to pay special attention when the virus mutates over time.

The results of gene sequencing last month posted on the GISAID data system showed that Omicron was the dominant variant, accounting for 99.8% of the patient samples that were sequenced. In which, Omicron’s sub-line is BA.2 accounting for the largest proportion, with 85.96%.
