Myth vs Fact
Truth deserves the last word.
Myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS), is a debilitating illness that affects millions of people worldwide. However, persistent myths and misunderstandings hinder its recognition and treatment. This year we are calling on you to help debunk six of the most common myths about ME and share the medical facts everyone should know.
With your support, we can change the narrative to get the facts right.






Challenge the myths, champion the facts.
ME knows no borders, and neither should our efforts to combat it. It is crucial that we work around the world to address this crisis.
COVID-19 continues to trigger a surge in the number of people affected by ME. Your voice is vital to ensuring this is addressed.
By fostering international cooperation, sharing research findings, and building recognition in every nation, we can pave the way for advancements in ME understanding and treatment.
Our goal is a world without ME.
Never underestimate the power of a share…
Challenge the myths, champion the facts. ME is a biological illness that disrupts the metabolism and impairs the brain, immune system and autonomic nervous system. #WorldMEDay #Fact
