A new report suggests that the average person with long covid didn't have a severe infection. Three-fourths of long covid patients were not hospitalized for covid-19, according to a study. Patients were most likely to be co-diagnosed with fatigue and trouble breathing, according to the researchers.

The International Classification of Disease (ICD-10), a codebook used by doctors, hospitals, and insurance companies for diagnostic and billing purposes, was codified last October. Patients with long covid were allowed to be formally recognized with this code. It gave researchers another way to study these patients.

One of the first pieces of research to do that is a report conducted by FAIR Health, a nonprofit company that claims to have the country's largest database of privately billed health insurance claims.

The authors used their database to identify 80,000 patients who had been diagnosed with post-covid symptoms after the ICD code was implemented. Most patients had never been hospitalized for their original case.

Robin Gelburd, president of FAIR Health, said in a news release that post-covid conditions have become an issue of growing national concern.

The more severe your initial infections, the more likely you are to experience more serious problems. Studies have shown that people with mild to moderate respiratory infections are more likely to develop a variety of health problems than people with other respiratory infections. People who catch covid-19 don't end up in the hospital. There are more survivors of severe illness in the group that had milder covid-19 than there are in the group that had milder covid-19.

The report's other findings might give insight into long covid. Older Americans are usually covered through public Medicare plans, so the most represented age group might be between 36 and 50 years old. Women were more likely to be diagnosed than men. Abnormalities of breathing, cough, and malaise/fatigue were the three most common conditions to be diagnosed at the same time. 30% of patients had never been diagnosed with a chronic illness before their long covid.

A white paper is an important part of scientific research because it hasn't gone through formal peer review. The findings should be taken with caution. Nothing should be the final word on anything. The sheer amount of data available does lend credibility to the results, and it is likely that other researchers will be able to use ICD-10 data for similar studies in the future.

The authors plan to analyze their data further, both to track the long-term outcomes of these patients and to examine whether vaccination reduced the risk of long covid.
