One Family's CVS & Covid Story


Hi there, I thought I’d share an experience my 24 year old son as just gone through! He started with covid symptoms, after being exposed to covid at work, 8 days into his 14 day isolation. he felt unwell and had a temperature, he took a covid test and it was positive, day 5 after onset of symptoms he said I feel like I’m getting my sickness mum (that’s how we generally refer to a bout of cvs) 
The next morning he did have his sickness. His cvs symptoms normally, from first vomiting till last vomit, lasts around 6-8 hours, on this occasion it lasted 6 days it was terrifying, I have never seen him so ill! 
I just wanted to highlight this with you not to scare anyone but to make fellow sufferers and their carers aware!
My son has had cvs since he was about 2 years old. Sue

Cece holding book


My name is Cece, I’m 25 and have had CVS for almost 15 years now but am still learning how to cope with it. I’ve found CVSA UK a source of help and inspiration, and so I first wanted to thank you. The family days have helped myself and my family get help and seek the right doctor after years of searching.

    You have to be a very strong person to get through life with CVS and so I think it’s about time the world recognised those who suffer from, or care for those with, the condition. I desperately want to support the work CVSA do and so, after 2 years work, I’ve published my first book, “Chikara: Stronger Than You Look” in which I describe my travels in Asia as a young female CVS sufferer – hoping to inspire but also raise awareness about the condition. 

   I have just released the book,  have released the book to raise awareness and give a voice to the silent CVS Warriors around the world. I will be donating 15% of Author Royalties to CVSA UK, to support the great work they do. I would also like to donate 15% of any Author Royalties that I may make to CVSA U.K..

The book is available on Amazon in Kindle or Paperback form.

We have no specific knowledge of how Covid-19 affects CVS sufferers.

Please be cautious and follow all government advice, particularly with regard to social distancing.


We have heard from a couple of families where a CVS sufferer has tested positive, during an episode. In both cases this did NOT complicate treatment. It is early days but it is an encouraging first piece of news.

If you have CVS and have/had the virus, please get in touch so we can share the information and any advice.

We are not aware of any evidence that CVS increases risk of becoming infected, or having a worse prognosis.

Some CVS sufferers find that even minor infections can trigger a CVS attack. Dealing with an infection and CVS at the same time would be a burden best avoided. The advice on social distancing and self-isolation can only help in this regard.


Every severe CVS attack that is prevented means one bed kept free for the NHS which will be under increasing pressure.

That being said, if you are having a severe attack do not hesitate to seek help.


The US Society has updated its site with some information





The US society in collaboration with MedicineX has produced a new resource to help explain CVS. Take a look here.





Adult Guidelines Published


The North American Society and their medcial advisors have complete a mammoth task and produced a concensus view on the current best evidence based guide to treatment of adult sufferers. Thanks to all involved for this important piece of work in support of CVS sufferers.


You can download the guidelines for your doctors to read here.


Updated Childhood CVS info.


It has been a few years since a medical society published guidelines for children with CVS, available here


Prof. B Li who was the main author has pubished an update available here

Mitochondrial DNA can be inherited via the father as well as the mother.


For a very long time it was thought only the mother passed on surviving mitochondria to a child. Recent research is casting doubt on that. This complicates our understanding still further. It is early days but as the finding was controvertial it was repeated, using different methods in different independant labs. It is a major finding for human biology, what it may mean, if anything, for CVS is less clear yet.

We hear of many sufferers who don't think they are being treated seriously, and struggle to get diagnosis or treatment. Some people have their jobs at risk due to what appears to their employer to be unexplained absences. Parents face the same issue with schoools, when a child has not got a diagnossis they recognise.
