Covid reinfection increases mortality risk

Does the danger of a long-term illness increase? It does, indeed. Reinfection with Covid increases the risk of complications related to pulmonary, cardiovascular, hematological, diabetes, gastrointestinal, kidney, mental health, musculoskeletal, and neurological disorders, hospitalization, and even death when compared to no reinfection, according to a study published in Nature Medicine.
According to a study based on an investigation of the national healthcare database of the US department of veteran affairs, the hazards are most obvious during the acute phase but they may still exist six months later.
Veterans in the database number 58.2 lakh. The researchers discovered that 40,947 individuals experienced reinfection and 4,43,588 individuals had only experienced one Covid infection. 53.3 lakh people reported having the illness. Data revealed that those with reinfection had higher odds of all-cause death, hospitalization, and a number of other predetermined outcomes than individuals without reinfection, according to the study.
The findings, according to the authors, demonstrated that reinfection, both during its acute and post-acute phases, raised the odds of all-cause death and unfavorable health outcomes.
Long-term Covid neuropsychiatric symptoms can include memory loss, anxiety, sleeplessness, migraines, seizures, and headaches. Patients who have recovered from the moderate to severe infection have also mentioned secondary bacterial infections, pneumonitis, and lung tissue scarring.
People who had COVID infection again had a risk of hospitalization and death that was more than twice as high as patients who had it just once. According to a study published in Nature Medicine, they also had increased risks for neurological illnesses, difficulties with the lungs, heart, blood, kidneys, and diabetes, as well as for issues with the bones and muscles, the brain, and the heart. Repeat infections increased the risk of developing lung issues by more than three times, heart problems by three times, and brain disorders by 60% compared to people who had only experienced one infection. The elevated risks were particularly noticeable in the first month following reinfection but persisted six months later, according to the researchers.
Covid-19 keeps surprising us. The research is intriguing, according to experts who weren’t involved in it. The belief that “if I survived my first infection, I’m really going to be just fine the second time” is one that I believe many people have. Really, there shouldn’t be any issues,’ ” claimed Columbia University clinical medicine lecturer Dr. Daniel Griffin.
On the podcast “This Week in Virology,” Griffin commented on the report, saying, “The general wisdom, right, is that reinfections are modest, nothing to worry about, nothing to see here.” But, he claimed, that isn’t actually corroborated.
This is not how it should operate. Our immune system often preserves its memory of how to recognize and fight against specific parts of viruses, even when they change shape, like the influenza virus does. They might still infect us, but the notion is that our previous immunity will act as some sort of shield and prevent major injury.
The blows keep coming for coronaviruses, particularly SARS-CoV-2 coronaviruses.
You can re-infect yourself with the same coronavirus a year later. Since coronaviruses naturally possess the capacity to interfere with long-lasting lifetime immunity, it is unclear whether the second infection can be more moderate, Griffin said.
