This article from Nature Medicine was published in August 2024 and gives an overview of Long Covid, explains what it is, how it affects people and what needs to be done to combat it. Here is a simplified summary:
What is Long Covid?
Long Covid is a condition where people continue to have health problems after recovering from the initial COVID-19 infection. It can affect many different parts of the body, such as the heart, brain, lungs and immune system. Common symptoms include extreme fatigue, brain fog (difficulty thinking clearly) and dizziness. These problems can last for months or even years.
How many people are affected?
Long Covid affects a very large number of people worldwide — around 400 million by the end of 2023. The condition even occurs in people who initially only had mild COVID-19. Vaccines and antiviral treatments can reduce the risk of getting Long Covid, but the problem is still widespread. People who contract COVID more than once have a higher risk of developing Long Covid.
How does Long Covid affect life?
Long COVID can be seriously disabling. Many people struggle to work, look after themselves or enjoy life as they used to. One in four people with Long Covid have to limit their social activities in order to continue working. Some people become unemployed due to their health problems. The condition also leads to isolation and stigmatisation, as some patients feel misunderstood or ignored by doctors and society.
Impact on healthcare systems and the economy
Healthcare systems are under great pressure due to the Long Covid. Patients need continuous care from multiple doctors, which increases healthcare costs and leads to longer waiting times for everyone. The economic impact is huge — studies estimate that Long Covid costs countries billions of dollars every year due to lost work and medical expenses.
What can be done?
The article calls for the following measures against Long Covid:
– Better prevention: improving air quality and increasing the use of vaccines can help prevent COVID infections and, therefore, long Covid.
– More research: Scientists need to better understand the disease, including its causes and how it can be effectively treated.
– Support for patients: There should be better systems in place for people with long COVID, including financial support and workplace adjustments (such as flexible working hours).
– Global coordination: Countries need to collaborate on research and policy solutions to address the long-term consequences of COVID-19.
Conclusion
Long Covid is a serious global health issue that affects millions of people, straining health systems and economies. More research, prevention efforts, and support for those affected are needed to manage the ongoing challenge it presents.
