Long COVID: Symptoms and Research

Overview

Long COVID is a condition that can affect people who have had COVID-19, even those who had mild or no symptoms. It is defined as symptoms that persist or develop after the acute phase of the infection, typically lasting more than 12 weeks.

Research on the long-term effects of COVID-19 is ongoing. However, studies have shown that some people who have had COVID-19 may experience ongoing health problems, such as: * Heart damage * Lung damage * Kidney disease * Liver disease * Mental health conditions

Research

Scientists are actively studying long COVID to understand its causes, symptoms, and potential long-term effects. The National Institutes of Health (NIH) is funding research to investigate the biological mechanisms underlying long COVID and develop treatments and interventions.

Conclusion

Long COVID is a complex and multifaceted condition that can have a significant impact on people's health and well-being. Ongoing research is providing valuable insights into its causes and effects, and is helping to develop strategies for diagnosis, treatment, and prevention.
