Using the same time frame, the researchers also compiled a control group of more than 443,000 people who had tested positive for one COVID-19 infection, and another group of nearly 41,000 people who had two or more documented infections. The researchers created a controlled data set of 5.3 million people who did not test positive for COVID-19 infection from March 1, 2020, through April 6, 2022. Patients represented multiple ages, races and sexes. Department of Veterans Affairs, the nation’s largest integrated health-care system. We really need to do our best to reduce the chance we will have a twin-demic of both COVID-19 and the flu this winter season.”įor this study, the researchers analyzed about 5.8 million de-identified medical records in a database maintained by the U.S. “People should do their best to prevent repeat infections by masking, for example, getting all of their eligible boosters, staying home when sick. heads into the winter months, with new variants emerging, mutating and already causing an upswing in infections in some parts of the country, Al-Aly said. Limiting exposure to the virus is especially important as the U.S. “And if you’ve had three infections, it’s best to avoid the fourth.” “This means that even if you’ve had two COVID-19 infections, it’s better to avoid a third,” Al-Aly said. “Without ambiguity, our research showed that getting an infection a second, third or fourth time contributes to additional health risks in the acute phase, meaning the first 30 days after infection, and in the months beyond, meaning the long COVID phase.”Īdditionally, the study indicated that the risk seems to increase with each infection. “During the past few months, there’s been an air of invincibility among people who have had COVID-19 or their vaccinations and boosters, and especially among people who have had an infection and also received vaccines some people started to referring to these individuals as having a sort of superimmunity to the virus,” said senior author Ziyad Al-Aly, MD, a clinical epidemiologist at the School of Medicine. Reinfection also contributes to diabetes, kidney disease and mental health issues. Such outcomes include hospitalization disorders affecting the lungs, heart, brain, and the body’s blood, musculoskeletal and gastrointestinal systems and even death. The researchers found that repeat SARS-CoV-2 infections contribute significant additional risk of adverse health conditions in multiple organ systems. Louis Health Care system shows the health consequences of reinfection. Now, a new study from Washington University School of Medicine in St. They’ve also determined that people can get COVID-19 a second or a third time, despite acquiring natural antibodies after the first infection and receiving vaccination and booster shots. Since the COVID-19 pandemic began almost three years ago, scientists have learned that an initial infection can lead to short- and long-term health risks affecting nearly every organ system in the body. Researchers led by Al-Aly found that repeat SARS-CoV-2 infections contribute significant additional risk of adverse health conditions in multiple organ systems. Louis Health Care system, examines data from a new study. Ziyad Al-Aly, MD, a clinical epidemiologist at Washington University School of Medicine in St. Researchers recommend masks, vaccines, vigilance to prevent reinfection News Release Repeat COVID-19 infections increase risk of organ failure, death
