International Awareness Day for Chronic Immunological and Neurological Diseases (CIND) helps raise awareness about a number of diseases including myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), fibromyalgia (FM), Gulf War syndrome (GWS) and multiple chemical sensitivities (MCS). The date was chosen as the official day as it's the birthday of Florence Nightingale who was believed to have suffered from ME/CFS. Around 12 May each year, buildings and landmarks around Australia light up in blue to raise awareness about ME/CFS.
