DEVELOPING COUNTRIES TAKE ACTION AGAINST "LIFESTYLE" DISEASES
In September the UN held its first ever High Level Summit on Non-communicable diseases 鈥� or NCDs - covering the worldwide increase in conditions such as heart disease, stroke and cancer. Nearly 80% of NCDs occur in developing countries. Following the summit many of them are already starting to take action. India has announced the world's largest NCD prevention programme and Fiji declared November to be Non-Communicable Disease Month. In Botswana, which was once known for its epidemic of HIV, reporter Letlhogile Lucas explains that there is now a push to educate people to exercise and eat more healthily.
