The severity of Covid-19 will not indicate long-term symptoms, the study shows


While the severity of the initial infection can vary widely, new research suggests that it is not an indicator of who is most likely to suffer from long-term symptoms.

To date, little has been known about lung health following infection with SARS-CoV-2, the virus that causes Covid-19.

But now, researchers at Trinity College Dublin have presented a new study to assess lung function and respiratory symptoms in patients in the full Covid-19 initial severity range.

The team found that although symptoms such as fatigue, health and breathing were all common symptoms after Covid-19, they did not appear to be related to the severity of the initial infection.

In a peer-reviewed paper published today (January 8) in the Annals of the American Thoracic Society, the study looked at a series of recovery measures for 153 patients who were followed in an outpatient setting an average of 75 days after 19 diagnostics.

The research found that 62% of patients felt they had not returned to full health, while 47% were classified as having fatigue. However, the results suggest that Covid-19 does not cause significant fibrosis, with lung scars observed on CT scans of only 4 pcs of participants.

Surprising results

While the findings show a significant burden of symptoms, there is a relatively low rate of abnormal objective findings. According to the researchers, this suggests that there is no simple diagnostic test for long-distance symptoms.

These results add to previously published work, which suggests that there is no simple diagnostic test for so-called long-distance symptoms and that the diagnosis is based on the symptoms reported by the patient.

Dr Liam Townsend, a researcher at Trinity College Dublin who led the research, said the team was surprised by the findings. We expected a higher number of abnormal chest x-rays. We also expected continued health measures and abnormal findings to be related to the severity of the initial infection, which was not the case, ”he said.

Our findings have implications for clinical care in demonstrating the importance of following up on all patients who have been diagnosed with Covid-19, regardless of the severity of the initial infection. It is not possible to predict who will have continuous symptoms. “
