Submitted articlle--Dr. Andrea Wilhelm of Queen Charlotte is one of the 30 physicians across Canada who have pledged their commitment to building healthy communities in Africa by signing up for Canadian Physicians for Aid and Relief's (CPAR's) 3rd Annual World Health Day Challenge. The challenge calls for health practitioners to donate part or an entire day's worth of their income in support development work in rural African communities on World Health Day, April 7. Dr. Wilhelm thinks the initiative is an appropriate way for doctors to make a financial commitment. She is one of 30 health practitioners across Canada who've registered. CPAR's World Health Day Challenge was inspired by Dr. N. Kevin Wade of Vancouver who donated a day of his medical service payment plans in 2002 and again in 2005.CPAR's health care work focuses on reducing the burden of HIV/AIDS through community awareness, preventing the spread of common diseases by increasing access to clean water and sanitation facilities, promoting healthy pregnancies and educating communities about sexual and reproductive health issues. The group works with rural African communities to develop primary health care, income generating, natural resource management and peace-building programs in support of a vision where 'health' is created and sustained by the environmental, economic and social well-being of a community.
