A study determined how long immunity lasts for recoveries from covid

People infected with coronavirus has little chance of contracting the disease again for at least six months, according to a study published today by the Oxford University.

This large-scale research on the immunity in the face of a possible new contagion of covid-19 It was conducted in collaboration with Oxford University Hospitals, although it has not yet been independently reviewed.





Their results confirm what many health professionals observe that more than 57 million people worldwide were infected with the SARS Cov-2 virus, but reinfection cases remain relatively few.

This is “very good news”, said Professor David Eyre, one of the authors of the research, who said that you can “be sure that, at least in the short term, most people who contract covid-19 They will not contract it again. “

The study is based on coronavirus tests carried out regularly on 12,180 health workers at university hospitals in Oxford over a 30-week period, according to AFP.

None of the 1,246 employees with antibodies developed a symptomatic infection, and only three, without symptoms, tested positive for the virus a second time.

We know from a previous study that antibody levels fall over time, but this latest study shows that there is some immunity in those who have been infected, “he clarified.

These results, however, contradict another British study published last October by Imperial College London and the Ipsos Mori Institute, according to which the immunity acquired by people recovered from coronavirus diminishes “quite rapidly”, particularly in patients asymptomatic, and could last only a few months.

Researchers from Oxford stated that they had not yet gathered enough data to make a judgment regarding what could happen six months after being infected with coronavirus.

However, their study has the ultimate goal of verifying how long immunity lasts overall.

At the same time, other research conducted at the University of St Andrews showed that people with coronavirus They are most likely to be highly infectious in the first week after symptoms appear.

According to work, usually within five days of the first symptoms of coronavirus, people are at increased risk of transmitting the virus, highlighting the importance of identifying and isolating cases early.

The study, published in The Lancet Microbe, was conducted by researchers at the University of St Andrews; the Western General Hospital, Edinburgh; University Hospital, Wishaw; the University of Edinburgh; Cotugno Hospital, Naples; and the University of Glasgow, and focused primarily on hospitalized people infected with coronavirus.

Muge Cevik from St Andrews University School of Medicine, lead author of the research, said that “this is the first systematic and meta-analysis review that has comprehensively examined and compared viral load and spread of the three coronavirus humans”.

Cevik also warned of the importance of increasing public awareness about the variety of symptoms related to the disease, including mild ones that can occur before or in the course of infection, and those that are stronger such as cough or fever, to allow immediate self-isolation treatment.
