The term “hậu COVID” in English is “post-COVID” or “post-COVID syndrome,” and it is also commonly referred to as “long COVID.” This condition describes a range of symptoms that persist or appear after the acute phase of a COVID-19 infection has resolved. Patients with post-COVID syndrome may continue to experience fatigue, shortness of breath, brain fog, chest pain, and a variety of other physical and mental health issues. Such symptoms can linger for weeks or even months, significantly affecting an individual’s daily life and overall well-being, regardless of the initial severity of their COVID-19 infection.

Researchers and healthcare professionals around the world are paying close attention to post-COVID syndrome because it poses new challenges for public health systems. Studies suggest that a significant proportion of individuals who recover from COVID-19 still suffer from lingering symptoms, making it crucial to develop strategies for diagnosis, treatment, and support. Rehabilitation programs, mental health services, and regular follow-up care have become increasingly important for patients experiencing long COVID. Understanding and addressing these long-term effects not only assist individuals in their recovery but also help to reduce the impact on families and communities.
