There are three different types of long-term covid and each has its own list of symptoms, scientists have claimed.

The sheer number of widespread symptoms has made it difficult for doctors to define their condition, with recent work claiming that there are more than 60 different manifestations of the condition, including hair loss and decreased libido.

Now research by academics at King’s College London, using data from the Zoe COVID Tracker app, has revealed that there are three distinct forms of the disease, also known as post-Covid syndrome.

In their research paper, the scientists say that future long-term covid research should “consider dividing affected individuals into different subgroups” as this could help researchers uncover how the mystery disease works and affects people. patients.

The researchers looked at 1,459 people living with long-term covid, defined by the study authors as suffering from symptoms for at least 84 days after infection.

The study claims that there is a neurological branch, a respiratory branch and a third form of long-term covid with a diverse range of more severe and widespread symptoms.

Those with neurological symptoms, including fatigue, brain fog and headaches, were most commonly found among those infected when the highest strains were alpha and delta, waves that hit Christmas 2020 and again. in the spring of 2021.

A second group experienced respiratory symptoms including chest pain, lung problems and shortness of breath. It was commonly detected in people infected during the first wave of the virus in spring 2020, when people had not been vaccinated.

King’s College said symptoms in the latter cluster included heart palpitations, muscle aches, skin and hair changes, and “debilitating multi-organ symptoms”. These three subtypes were evident in all variants, but they did not put a percentage risk on each, the researchers said.

Clinical lead author Dr Claire Steves, of King’s College London, said: “These data clearly show that post-Covid syndrome is not just one condition, but that there appear to be many sub-conditions. -kinds.

“Understanding the root causes of these subtypes can help find treatment strategies,” Dr. Steves said. “Furthermore, these data underscore the need for long-term COVID services to include a sensitive and individualized approach to each individual’s issues.”

Research published last week by the University of Birmingham showed the list of longstanding Covid symptoms now stands at 62. Loss of smell, shortness of breath and chest pain were the most common symptoms of Covid. study, with amnesia, inability to perform familiar movements and hallucinations.
