People who’ve had COVID are likely to be secured from reinfection for at least 5 months and have a comparable defence to someone who’s been immunized, according to a UK study.
However does it mean those who have recovered are no longer a risk to others?
More than 20,000 healthcare employees from 102 NHS trusts across the nation, including frontline staff, have been tested since June by the Public Health England (PHE) Siren study
Some 6,614 of them checked positive for antibodies at the start of the research study, suggesting they ‘d had the infection previously in the first wave.
It’s a huge friend of individuals so its outcomes are valuable – and the study is still ongoing.
How many people contracted COVID a 2nd time?
There were just 44 prospective reinfections from the 6,000- plus discovered to have antibodies.
Two of them were deemed “possible” cases, while 42 were “possible”, based on the evidence offered.
What does it indicate for the chances of contracting the infection once again?
If all 44 cases are presumed to be validated reinfections, the security rate is 83%compared with those who’ve not had it in the past.
If only the two “probable” cases are thought about, the rate would be 99%, but scientists are opting for the headline figure of 83%.
Nevertheless, PHE says more work is going on to clarify this range.
The length of time does the security last?
It seems a minimum of 5 months, usually, from first getting ill.
The analysis of the results was done towards completion of 2020, and the study is still following the individuals to see if it lasts longer.
The research study’s lead, Professor Susan Hopkins, warned the defense “is not total and we do not yet know how long [it] lasts”.
In spite of the uncertainties, Dr Julian Tang – a scientific virologist at University of Leicester – said the outcomes were still “beneficial and comforting news” for medics on the frontline.
It’s also important to keep in mind that the study was done before the new UK version – which transmits much more easily – had actually become widespread.
Scientists are therefore also looking at whether “very first wave” antibodies provide security versus it.
How does this ‘natural’ protection compare to vaccines?
Vaccines being presented in the UK, such as the Pfizer and Oxford jab, can provide over 90%security after two shots.
The vaccines might likewise have to be tweaked to deal with brand-new versions of the infection – such as the one that’s been determined recently in Brazil
If I’ve had COVID in the past, can I still pass it on?
It’s very possible, and the study’s authors alert that an individual with antibodies may still be a clear danger to others.
PHE stresses it’s “vital that everybody continues to follow the guidelines and stays at home, even if they have actually previously had COVID-19“.
This means continuing to stick to lockdown steps and practise safety procedures such as social distancing, using a face covering and routine handwashing.
Will COVID be ‘much easier’ the second time, and will I show signs?
The two “probable” reinfection cases in the study stated their signs were less extreme the 2nd time – however it’s prematurely to state for sure.
Nevertheless, if it were to follow other coronaviruses, a 2nd infection might turn out more small.
Teacher Lawrence Young, a virologist from Warwick Medical School, said studies on typical cold coronaviruses show that any reinfection “is not likely to result in extreme disease”.
But one noteworthy difference with getting COVID-19 again, appears to be the likelihood of not showing any symptoms at all.
The study discovered people who were reinfected were significantly most likely to be asymptomatic (66%) than those contracting COVID for the first time (22%), stated Professor Paul Hunter, from the Norwich School of Medication.
