#MEAction UK and Scotland update prevalence figures based on new data

Both the UK and Scotland branches of #MEAction will start using updated figures for the prevalence of ME, based on a recent US survey.

Unfortunately, all prevalence estimates for ME are of limited accuracy. This is due to a range of factors including, but not limited to, uncertainty around diagnosis, lack of confidence among healthcare professionals, and possible confusion with overlapping conditions. However, it is necessary for our campaigning work to decide on a figure, and ideally one that is informed by the latest data.

The Center for Disease Control (CDC) has published results of a survey which provides data following the onset of the COVID-19 pandemic and is the most recent credible data we are aware of. Importantly, it will include any increase in the prevalence of ME due to the pandemic, as well as many with Long Covid, due to the overlaps between the two conditions.

The US survey results show that 1.3% of adults in the US have ME/CFS. This is significantly higher than the 0.4% estimate derived from UK Biobank data before the COVID-19 pandemic and used in the NICE guideline on ME/CFS.

Applying these new estimates to UK populations gives estimates of 700,000 people with ME in the UK and 58,000 in Scotland. Prior to this we were using figures of 250,000 and 22,000 respectively.

The survey did not include children with ME, which is a common shortcoming of ME research. We urgently need more information about the prevalence of ME in children across the UK and globally, and this is an issue our groups will keep campaigning on. We would also welcome the replication of this survey in the UK population.

  1. I’m confused by these figures as Scotland is part of the UK. Does that mean there’s likely to be 758,000 ME sufferers in the UK in total? Can you please clarify. That’s a massive jump in numbers

    1. #MEAction Scotland

      Hi Bekky, apologies that this wasn’t clear. The total figure for the UK is 700,000 people with ME. The 58,000 people in Scotland are already included in the UK figure because, as you say, Scotland is part of the UK. We have also mentioned Scotland separately because health is devolved in Scotland, so that more specific figure will be used by #MEAction Scotland when they are engaging with Scottish policy and bodies. Thanks.

  2. Sorry to ask but do these new figures take into account the 45 or 54%(depending what research papers you look at) of Long Covid patients who would now meet the diagnostic criteria for ME/CFS please? Thank you.

 Black ME Voices: Q&A with Teona Studemire

With it being Black History Month, it was crucial to me to make sure we spotlighted someone from the ME/CFS and Long COVID community who is Black. Being Black and disabled is an entirely different experience. Not only do we deal with ableism, but we also deal with racism, especially medical racism. According to the
