The new US long-term study of COVID-19 provides new evidence that it can occur in infected people even when infections have started and that the elderly are at greater risk for long-term side effects.
Შi Learning Of the veterans posted Wednesday, about a third who had breakthrough infections showed signs of chronic COVID.
A separate report from the Centers for Disease Control and Prevention found that one year after 4 years of primary Corovirus infection, 1 in 4 adults 65 years of age and older had at least one potential long -term COVID health problems, compared with 1 in 5 adolescents. .
Chronic COVID refers to any of the more than two dozen symptoms that persist, recur, or first appear at least one month after coronavirus infection. It can affect all parts of the body and can include fatigue, shortness of breath, fog in the brain, and blood clots.
Coronavirus vaccines, which help prevent major infections and serious diseases, provide some protection against chronic COVID, but growing studies show that not as much as scientists expected.
The study of veterans, published in Nature Medicine, looked at the medical records of 60-year-old white male veterans on average. Of the 13 million veterans, nearly 3 million were vaccinated last year, including October.
About 1% or about 34,000 developed success infections. Lead author Dr Ziad al-Ali noted that the study was conducted before the highly infectious variant of omicron appeared later this year and said the success rate of infections was likely to rise.
Breakthrough infections and chronic COVID symptoms are more common in those receiving a Johnson & Johnson vaccine than two doses of Moderna or Pfizer vaccines. It is not known if anyone received amplifier hits; The first amplifier was not approved in the United States until the end of September.
Overall, 32% had chronic symptoms of COVID for up to six months after the infection began. This compared with 36% of unvaccinated veterans who became infected and had chronic COVID.
Vaccination reduced the chances of chronic COVID symptoms by a “moderate” 15%, but halved the risk of breathing or coagulation problems, says al-Ali, a researcher at the University of Washington and Veterans Health System in St. Petersburg. Louis. These symptoms include shortness of breath or persistent coughing and blood clots in the lungs or veins in the legs.
Infectious disease expert Dr. Christine Englund, who runs COVID’s long-term patient center at the Cleveland Clinic, said the Nature Medicine study reflects what she sees in her clinic. In the long run, COVID patients included people who had been vaccinated and received boosters.
“Since we don’t have a clear treatment for long-term brood, it’s important to vaccinate everyone and use other proven methods of prevention, such as masks and distance from other people, to prevent COVID infections and, consequently , the long -term COVID ”Englund said.
The Centers for Disease Prevention and Control Report, released Tuesday, used the medical records of nearly 2 million American adults since the pandemic began between March 2020 and last November. These included 353,000 who had COVID-19. Patients were monitored for one year to determine if they had developed any of the 26 health conditions associated with prolonged brood.
Those who have had Covid are more likely than other adults without COVID to have one of these conditions, and the risk is greater for people age 65 and older. Vaccination, gender and race information are not included.
Breathing problems and muscle pain are the most common conditions.
The risk of aging is higher for certain conditions, including stroke, brain fog, kidney failure, and mental health problems. The findings are troubling because these conditions may accelerate older people’s needs for long-term care, the report’s authors said.
They stressed that regular screening of all COVID patients is “essential in reducing the incidence of chronic COVID.
