Scientists reveal Omicron variant 2.4 times more likely to be reinfected for people who already have HAD Covid

Scientists have revealed that OMICRON is 2.4 times more likely to be re-infected than people who have had Covid.

Variant has a “significant” ability to alter immunity in people previously infected with the virus, the first real-world study of New variant found.

South Africa’s National Institute of Infectious Diseases (NICD) warned its report had “important global public health implications” because Omicron fueled a spike in cases.

NICD data yesterday showed 11,535 new Covid cases were recorded in the past 24 hours, up 368% from last Thursday’s figure of 2,465.

Of the 51,402 people who took the test, a whopping 22.4% tested positive – up from 3.6% last Wednesday.

Only a quarter of people in South Africa are fully vaccinated, but previous infections from other strains of Covid have built up natural immunity.

The infection was previously detected to reduce the risk of catching Covid, but Gauteng province – where 80% of the people have tested positive before – is still the case. the epicenter of South Africa’s current explosion of cases.

Hospitalizations also spiked 180% last week, with 98 Covid patients hospitalized last Thursday compared to 274 Covid patients yesterday.

It comes as Omicron continues to spread in the UK with suspicion The number of cases increased rapidly in just five days, although confirmed infections are 42.

More than 19 million Britons are now fortified – a third of the population over the age of 12, with one study showing that three stabs “massively” boosted the body’s defenses from Covid.

“We found evidence of a significant and ongoing increase in the risk of reinfection. the ability to infect previously infected individuals,” the NICD researchers said.

“Immunity from prior infection, even if Omicron can also ward off vaccine-derived immunity, has important global public health implications.”

They added: “Urgent questions remain regarding whether Omicron can evade vaccine-induced immunity and the potential impact of reduced immunity to infection on infection. protect against severe illness and death.”

NICD researchers say there have been 35,670 reinfections in 2,796,982 cases examined since last March.

The study found that the risk of re-infection of Omicron was significantly higher than that of the Beta and Delta variants during the second and third waves.

Scientists from the NICD say the data suggests that Omicrons may be less likely to cause severe disease than previous variants.

But many of the first cases were in younger patients, which could skew the data.

Professor Paul Hunter, University of East Anglia’s Norwich Medical School, said: “The implication of this paper is that Omicron should be able to overcome natural immunity and possibly vaccine induced to some extent. significantly.

“However, the extent remains unclear although it is doubtful that this would represent a complete escape.

“The other major uncertainty is whether this increases the risk of severe illness, hospitalization and death.”

NICD’s Dr. Michelle Groom says scientists are examining the variant’s ability to escape immunity.

She later tweeted: “More cases in younger age groups more likely to have mild illness.

“We need to wait and see how the variation works in other age groups.

The infection that used to be used to protect against Delta but now with Omicron seems to be gone

“It also takes time for severe illness to manifest so we’ll know more in the coming weeks.”

The World Health Organization (WHO) has sent a team of experts to Gauteng to help tackle the Omicron rise.

Anne von Gottberg, a microbiologist at the NICD, says about 75% of the samples sequenced are Omicrons.

“Infections used to be to protect against Delta but now with Omicron that doesn’t seem to be the case,” she said.

‘OPTIMIZED ROOM’

But Barry Schoub, chairman of the South African government’s committee on a COVID vaccine, told Sky News that early signs were “good”.

“Certainly, at this stage, the news looks promising – the majority of breakout infections (in other words, individuals who have had the infection despite being vaccinated) are mild,” he said.

Earlier this week, Israel Health Minister Nitzan Horowitz said people who received two doses of Pfizer vaccine and a booster shot were “more likely to be protected” against Omicron.

He added: “There is room for optimism and there are early signs that people who receive the active vaccine or the booster will also be protected from this variant.

“Right now, vaccines are really important. Anyone exposed to a variant that doesn’t have a vaccine is putting themselves at unnecessary risk.”
