Treating Covid-19 remains one of the biggest challenges in society.

In an effort to generalize the information and impact of post-Covid-19 symptoms lasting for 4 years since the disease was first identified, the study showed that the estimated economic cost from factors such as health care services, people with long-term Covid-19 unable to return to work... is about 1,000 billion USD worldwide per year, equivalent to 1% of global GDP.

In addition, about 6% of adults worldwide have suffered from long-term post-Covid-19 symptoms; many have yet to fully recover, and treating the disease remains one of the biggest challenges.

According to clinical epidemiologist Ziyad Al-Aly at Washington University in St. Louis (USA), co-author of the study and head of research and development at the VA St. Louis health care system, the above work of him and his colleagues also aims to provide a roadmap for policy and research priorities.

Also participating in this project are a number of other leading Covid-19 researchers and three leaders of the Patient-Led Research Collaborative, founded by patients with prolonged post-Covid-19 symptoms and professional researchers.
