The Democratic Republic of Congo has the highest rate of malnutrition in central and west Africa, affecting 43 percent of children under five, UNICEF said. In central Africa, 'some countries have a rate of chronic malnutrition which is still alarming,' Marianne Flach, the representative of the UN children's agency in Congo, said at the opening of a regional workshop on reducing malnutrition. At least 75 experts from different countries in central Africa came to take part in the workshop, which will continue until Thursday in a northern suburb of Brazzaville.
