There are three different types of long Covid and each has its own set of symptoms, according to researchers.

Experts from King’s College London examined 1,459 people living with long Covid - defined by the study authors as suffering symptoms for at least 84 days after infection - and found there appeared to be three “subtypes” of the condition.

A pre-print of the study, published on medRxiv, revealed people with long Covid appeared to be split into three main groups, including:

• Those with neurological symptoms including fatigue, brain fog and headache – most commonly found among those who became infected when the most dominant strains were alpha and delta.
• A second group who experienced respiratory symptoms, including chest pain and shortness of breath. This was found more commonly among those infected during the first wave of the virus.
• A final group experiencing a range of symptoms including heart palpitations, muscle ache and pain, and changes in skin and hair, King’s College said.
