Since 2020, the disease often called Long COVID-19 has been a widespread disability They affect the health and quality of lifetime of tens of millions of individuals around the globe and price economies billions of dollars in Reduced worker productivity and general decline in workforce.
The intensive scientific efforts triggered by Long COVID led to greater than 24,000 scientific publicationsmaking it essentially the most researched health condition in 4 years of recorded human history.
Long COVID is a term that describes Constellation of long-term health effects brought on by infection with the SARS-CoV-2 virus. These range from persistent respiratory symptoms akin to shortness of breath, to debilitating fatigue or brain fog that limits people's ability to work, to conditions akin to heart failure and diabetes which are known to last a lifetime.
I’m a physician and scientist and have been intensively involved in research into Long COVID because the early days of the pandemic. I actually have testified before the US Senate as Experts on Long COVIDhave published intimately about it and was named as one among the The 100 most influential people in healthcare in accordance with Time in 2024 for my research on this field.
In the primary half of 2024, a Flood of reports And scientific work on Long COVID have brought more clarity to this complex disease. In particular, this includes insights into how COVID-19 can damage many organs years after the initial viral infection, in addition to recent insights into viral persistence and immune deficiency that persist months or years after the initial infection.

How long COVID affects the body
A brand new study that my colleagues and I published within the New England Journal of Medicine on July 17, 2024, shows that the Risk of long COVID disease decreased over the course of the pandemic. In 2020, when the unique strain of SARS-CoV-2 was predominant and there have been no vaccines, about 10.4% of adults who contracted COVID-19 developed Long COVID. By early 2022, when the omicron variant family was predominant, that rate dropped to 7.7% amongst unvaccinated adults and three.5% amongst vaccinated adults. In other words, unvaccinated people were greater than twice as more likely to develop Long COVID.
Although researchers like me don’t yet have concrete numbers on the present rate in mid-2024 since it takes some time for Long-COVID cases to be reflected in the info, the influx of latest patients into Long-COVID clinics was comparable to that of 2022.
We concluded that the decline is on account of two essential aspects: the provision of vaccines and changes within the properties of the virus. This makes the virus less vulnerable to causing severe, acute infections and will now not have the option to persist within the human body long enough to cause chronic disease.
Although the danger of developing Long COVID has decreased, even a 3.5% risk remains to be significant. New and repeat COVID-19 infections are resulting in tens of millions of latest Long COVID cases, adding to the already horrifying number of individuals affected by the disease.
Estimates for the primary 12 months of the pandemic suggest that a minimum of 65 million people worldwide have Long-COVID. Together with a bunch of other leading scientists, my team will soon publish updated estimates of the worldwide burden of Long-COVID and its impact on the worldwide economy through 2023.
In addition, a crucial recent report from the National Academies of Sciences Engineering and Medicine provides full details Health effects that make up Long COVIDThe report was commissioned by the Social Security Administration to know the impact of Long COVID on their disability advantages.
It concludes that Long COVID is a posh chronic disease that could cause over 200 health effects on multiple body systems. These include the brand new onset or worsening of:
Long COVID can affect people of all ages, from children to older adults, no matter race, ethnicity and health status. greater than 90% of individuals with Long COVID had mild COVID-19 infections.
The National Academies report also concluded that Long COVID may end up in an inability to return to work or school, decreased quality of life, limited ability to perform activities of every day living, and declines in physical and cognitive function for months or years after initial infection.
The report points out that many health effects of Long COVID, akin to post-exertional malaise and chronic fatigue, cognitive impairment and autonomic dysfunction, usually are not currently included within the List of impairments by the Social Security Administrationcan, nevertheless, significantly impair an individual's ability to take part in work or school.
A great distance
In addition, health problems resulting from COVID-19 can persist for years after the initial infection.
A big study published in early 2024 showed that even individuals with a mild SARS-CoV-2 infection still related to recent health problems related to COVID-19 within the third 12 months after the initial infection.
Such results are consistent with other studies showing that the Virus persists in various organ systems for months or years after COVID-19 infection. And research shows that immune responses to the infection still visible for 2 to 3 years after a light infection. Together, these studies could explain why a SARS-CoV-2 infection years ago could cause recent health problems long after the initial infection.
Important progress can be being made in understanding the pathways through which long-COVID disease damages the body. Two preliminary studies from the USA And the Netherlands show that when researchers transfer autoantibodies – antibodies produced by an individual's immune system that concentrate on their very own tissues and organs – from individuals with Long COVID to healthy mice, the animals develop symptoms much like Long COVID, akin to muscle weakness and balance problems.
These studies suggest that an abnormal immune response chargeable for the formation of those autoantibodies may underlie long-COVID disease. Removal of those autoantibodies might be promising as potential treatments.
A persistent threat
Despite overwhelming evidence of the widespread risks of COVID-19, many messages suggest that it now not poses a threat to the general public. Although there isn’t any empirical evidence to support this, this misinformation has permeated public opinion.
However, the info tells a special story.
COVID-19 infections further more flu cases and result in more hospital stays And Death than the flu. COVID-19 also results in more serious long-term health problems. The trivialization of COVID-19 as a trivial cold or Equating it with the flu doesn’t correspond to reality.
