By analyzing data obtained from 122,000 molecular swabs, a research team from Fornaroli Hospital in Magenta determined that the risk of re-infecting SARS-CoV-2 with the coronavirus is extremely rare. In one year, only 5 out of 16,000 positive patients were re-infected. Figures adjusted for age, gender and race show that the risk of re-infection is only 0.07%.
one year laterinfection give Coronavirus SARS-CoV-2, Chance of staying again Infected Extremely low, equal to 0.07%. A new one proves this Study in Italy Who investigated the case Reinfection happened at Lombardy, The area was hardest hit by the first wave of violent tsunami COVID-19 pandemic In my country. It should be emphasized that the study assessed the time interval before the virus spread. Variations of concern, feature is mutation About “Immune Leakage” Protein S As E484K, Found in those Brazilian electronic South AfricanAfter the emergence of this variant in Brazil-especially in the city of Manaus-the reinfection boom is not accidental, it is not accidental. P.1. So the results mainly refer to the “wild” strain of the original virus Wuhan.
In order to determine that the risk of re-infection with the SARS-CoV-2 coronavirus is very low, a research team from Magenta Fornaroli Hospital and Azienda Socio Sanitaria Territoriale (ASST) Ovest Milanese conducted a study. The researchers were coordinated by Professor Antonino Mazzone, Director of the Medical Field, Chronic Diseases and Continuity Care of the Lombardy ASST, and came to their conclusions after conducting a study. Observational cohort study More than 122,000 results Molecular buffer. Within one year of starting the investigation, their polymerase chain reaction test was positive (Polymerase chain reaction) 15,960 swabs, of which 1,579 were during the follow-up period.Both patients were included in the study Symptomatic that Asymptomatic The average age is 59, and they are recruited through various screening and contact tracing programs.
By comparing all the data, it was found that only 5 patients had a molecular swab test that was positive again, but no one had a pathological condition. “Clinically significant“(Only one person was hospitalized). This means that after adjusting the data for age, gender, and race, the risk of reinfection in this cohort was found to be only 0.07%. Professor Mazzone announced to ADNKronos that the average interval between first reinfections was 230 days, Just after 7 and a half months. To make this result even more important, four of the five patients who tested positive again had close relationships with health care institutions (two worked there, one moved to RSA, and the other received blood transfusions in the hospital every week. ), so everyone is particularly concerned about being exposed to the risk of infection. “Reinfection is defined as the second positive RT-PCR 90 days after the first infection completely resolved, and at least two consecutive negative test results between attacks,” the authors wrote.Learning summary.
Professor Mazzone pointed out that “of the 13,496 people who were not infected with SARS-CoV-2 initially, 528 people subsequently developed primary infections”, so the “morbidity rate per 100,000 residents” equals 1 for reinfection, and new infections for 15.1. infection. “” When a variant of the pandemic coronavirus began to spread in our territory, the observation was over-Professor Pierangelo Clerici, Chairman of the Italian Association of Clinical Microbiologists (AMCLI) responded-so we cannot estimate how this variable affects the final The impact of the results”.
