37% of people had at least one long-COVID symptom diagnosed in the 3-6 month period after COVID-19 infection. The most common symptoms were breathing problems, abdominal symptoms, fatigue, pain and anxiety/depression.

3D rendered Coronavirus

This new study from the University of Oxford and the National Institute for Health Research (NIHR) Oxford Health Biomedical Research Centre (BRC) investigated long-COVID in over 270,000 people recovering from COVID-19 infection, using data from the US-based TriNetX electronic health record network.

The study reports on how commonly nine core long-COVID symptoms were diagnosed, and how this rate compared to people recovering from influenza. The nine core long-COVID symptoms, occurring 90-180 days after COVID-19 was diagnosed, comprise:

  • Abnormal breathing – 8%
  • Abdominal symptoms – 8%
  • Anxiety/depression – 15%
  • Chest/throat pain – 6%
  • Cognitive problems (‘brain fog’) – 4%
  • Fatigue – 6%
  • Headache – 5%
  • Myalgia (muscle pain) – 1.5%
  • Other pain – 7%
  • Any of the above features – 37%

Higher rates were seen if the whole 1-180 day period after COVID-19 infection was included.

New evidence for how our brains handle surprise

A new study from the Bruno Group is challenging our perceptions of how the different regions of the cerebral cortex function. A group of ‘quiet’ cells in the somatosensory cortex that rarely respond to touch have been found to react mainly to surprising circumstances. The results suggest their function is not necessarily driven by touch, but may indicate an important and previously unidentified role across all the major cortices.
