repeated infections by COVID-19 they increase the risk of death or lung, heart or brain problems, and the more times you contract the disease it seems to go up more, indicates a study published today by Nature Medicine.
People can be infected a second or third time with covid despite having acquired natural antibodies after suffering from the disease for the first time and having received vaccinations and boosters.
Research from the Washington College of Medicine and the St. Louis Veterans Affairs Health System shows that repeated infections with SARS-CoV-2 they contribute to a significant additional risk of adverse health conditions in multiple organs.
Getting an infection a second, third, or fourth time contributes to additional health risks in the acute phase, that is, the first 30 days after infection, and in the months afterward, explained study lead author Ziyad Al-Aly. .
These consequences include hospitalization, disorders affecting the lungs, heart, brain, and the body’s blood, musculoskeletal, and gastrointestinal systems, and even death. Reinfection also contributes to diabetes, kidney disease, and mental health problems.
People with reinfections from COVID-19 they were twice as likely to die and three times as likely to be hospitalized as those who had not had the infection multiple times.
Additionally, they were 3.5 times more likely to develop lung problems; 3 to suffer from heart conditions and 1.6 to experience brain conditions.
The risk “seems to increase with each infection”which means that even if you have had two infections by COVID-19it is better to avoid a third one,” Al-Aly said. “And if you have had three infections, it is better to avoid the fourth”.
people must do “everything possible to prevent recurrence of infections” with measures such as wearing a mask, getting vaccinated and staying home when sick, he recommended.
And he stressed that we must try to reduce the possibility of having a double epidemic of covid-19 and flu this winter.
Using a statistical model and a database from the Department of Veterans Affairs of USA, the largest integrated health system in the country, created a data set from March 2020 to April 2022.
In it there were 5.3 million people who had not had covid; 443,000 people with one infection and 41,000 people with two, three and even four. The study took into account variants such as the delta, the omicron and the BA.5.
