Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), is a condition that can cause ongoing symptoms and complications after an initial COVID-19 illness. The symptoms can range from mild to severe and may be similar to those of other illnesses.
Most people with Long COVID experience significant improvement within 3 months, while others may see improvement up to 6 months after symptoms first appear. However, some individuals may experience health problems that require comprehensive care and can result in disability.
Long COVID symptoms and conditions can include a wide range of health issues, such as:
– Tiredness or fatigue
– Respiratory and heart symptoms like difficulty breathing, coughing, and chest pain
– Neurological symptoms like headaches, sleep problems, and dizziness
– Digestive symptoms like diarrhea, stomach pain, and constipation
– Joint or muscle pain
– Rash
– Changes in menstrual cycles
Some people with Long COVID may experience unexplained symptoms that are difficult to diagnose and manage. This can lead to stigma and delays in diagnosis and treatment.
Long COVID complications can include multi-organ effects or autoimmune conditions lasting weeks, months, or even years after the initial illness. These complications can increase the risk of developing new health conditions such as diabetes, heart conditions, blood clots, neurological conditions, and post-intensive care syndrome (PICS).
The exact cause of Long COVID is still unknown, but research suggests that it may be related to the persistent inflammation caused by the virus. The CDC is working with partners to better understand and support individuals suffering from Long COVID.
