With the omicron variant spread to more than 60 countries, there is more understanding about its various aspects.
One such aspect is the unusual symptoms reported by a doctor in north London. According to David Lloyd, MD, a general practitioner, 15% of children with oomicrons in the area have spots on their body. So far, the most common symptoms of COVID-19 have been cough, fever, fatigue, and loss of taste and smell. He told Sky News that anything beyond that puts him at risk of not being discovered.
The Omicron jigsaw puzzle is still incomplete and the data is gradually rolling over. For example, Angelique Coetzee, a general practitioner in South Africa and president of the South African Medical Association, reported on November 27 that most of the omicrons she saw were “very, very mild.” Some of them showed different symptoms than usual, she added.
According to Coetzee, one such case was a 6-year-old boy with a fever and a “very high heart rate”. While Coetzee was considering whether or not to take the baby to the hospital, a follow-up call two days later revealed that the baby’s health had improved significantly.
“What we’re seeing clinically in South Africa – and remember I’m at the epicenter, where I’m training – is very mild… We haven’t admitted anyone [to the hospital]. I spoke to my other colleagues: the same picture,” she told the BBC.
But the full potential of omicron’s effect on the unvaccinated, the elderly and global covid-19 management is not yet known.
“There is still limited data on clinical severity of omicron,” the World Health Organization said on December 10, while preliminary results from South Africa suggest it may be less severe than Delta, and all cases reported in the EU/EEA to date were It is mild or asymptomatic, and it remains unclear to what extent Omicron may be less virulent in nature.”
Are vaccines effective against Omicron?
Cases among children, including one in India, can be attributed to the fact that many countries have not yet vaccinated children.
However, the new variant, which contains more than 30 mutations on the skeletal protein of the coronavirus, will likely evade some of the immunity conferred by vaccines. Early studies from the UK’s Health Security Agency show that Omicron reduces the effectiveness of two-dose vaccines such as Pfizer and AstraZeneca. For comparison, the AstraZeneca vaccine offered up to 60% protection against the delta variant 25 weeks after the dose was completed. In the case of omicron, this is down to 40%.
But the study showed that a third dose significantly improved the number of antibodies and provided increased protection against omicron.
A major question remains, though: Could an omicron be as infectious as a delta?
Is Omicron as bad as Delta?
Some early results suggest that omicron may spread faster than the delta variant, which has been, by far, the most transmissible type of coronavirus to date.
But the WHO is not yet clear whether the faster spread translates to the omicron’s inherent virulence.
Based on the limited evidence that exists, Omicron appears to have a growth advantage over Delta. “He. She [omicron] It spreads faster than the delta variant in South Africa where delta circulation was low, but it also appears to spread more quickly than the delta variant in other countries where delta incidence is high, such as in the UK,” the WHO said.
It cannot be said conclusively whether the rapid growth rate of omicrons observed in countries with high levels of population immunity is related to immune evasion from previous infections and vaccines, increased intrinsic transmissibility of the variant, or a combination of both.
“However, given the data currently available, it is likely that Omicron will outperform the delta variant where community transmission occurs,” the WHO said.
