Annual Cri du Chat Awareness Day is 5 May,
Annual Cri du Chat Awareness Week is the first week of May.
Cri du Chat Syndrome is relatively rare (1 in 25 000 to 50 000 births) so it is not surprising that it is unknown to most people and often little understood by professionals who may have little or no direct personal knowledge of persons with Cri du Chat syndrome. Raising awareness of the condition is a step toward ensuring that the most appropriate support is available.
The 5P Minus Society (USA) promotes a week of international awareness each year to raise awareness and encourage support of those with Cri du Chat Syndrome or related conditions. On at least one day of that week, people who are aware of Cri du Chat are encouraged to wear striped socks, one long and one short to represent the complete and deleted chromosomes.
Although there is a focus on activity during the international awareness week it is helpful to take any available opportunity to raise awareness of Cri du Chat among professionals and the general public.
