Three types of long COVID identified with different symptoms

There appear to be three different types of long COVID, each with their own symptoms, researchers have discovered. One group experiences neurological symptoms including fatigue, brain fog and headache, which most often affect those who contracted the virus when the Alpha and Delta variants were most prevalent, according to experts at King's College London. A second group suffers from respiratory issues, including chest pain and severe shortness of breath, which could point to lung damage. These symptoms were common among those infected during the first wave of the pandemic.
