The most frequent symptoms that Long Covid has left us with, according to a new

Post-exercise sickness, fatigue, clouding of consciousness, dizziness, gastrointestinal symptoms, palpitations, decreased desire or sexual problems, loss of smell or taste, thirst, chronic cough, chest pain, abnormal movements.

These are the 12 main symptoms that, according to the first results of a study conducted on almost 10,000 Americans, have left behind prolonged infection with the COVID-19 virus.

The discomfort can last for months or years after infection, and according to the research team, funded by the US National Institutes of Health, "Long Covid" is more frequent and severe in people who are unvaccinated or infected with pre-Omicron variants.

Frequent re-infection was also found to be associated with increased frequency and severity of prolonged Covid.

The study, published in Jama, is part of the NIH project entitled: "Searching for Covid to improve recovery".

It was born with the aim of understanding why some people develop long-term symptoms after infection with Sars-CoV-2 and also to identify, treat and prevent prolonged Covid.

The researchers looked at data from 9,764 adults, including 8,646 affected by Covid.

They assessed more than 30 symptoms in different areas of the body and organs, then performed statistical analysis, identifying the 12 symptoms that most distinguish people with and without prolonged Covid.

Finally, they created a scoring system based on patient-reported symptoms, which will help doctors and researchers better identify cases.

Researchers have identified more than 200 symptoms associated with the disorder that occur or persist for more than 30 days after infection.

But a true definition of "Long Covid" does not exist to date and this is what the researchers of the project want to achieve.
