“I want my leadership to be judged by the impact of our work on the health of two populations: women and the people of Africa.” This is how Dr. Margaret Chan, the current Director-General of the World Health Organization , described her leadership mission. The reason behind this mission is evident. Women and girls constitute 70% of the world’s poor and 80% of the world’s refugees. Gender violence against women aged 15–44 is responsible for more deaths and disability than cancer, (...) malaria, traffic accidents, and war. An estimated 350,000 to 500,000 women still die in childbirth every year. The negative health implications of absolute poverty are worst in Sub-Saharan Africa and South Asia. Hence, Chan aims to have the biggest impact on the world’s poorest people. (shrink)

The pathogenesis of dengue haemorrhagic fever has been the subject of intense research and considerable controversy. One hypothesis proposes that the immune response in a sensitized host is the primary mechanism. In contrast, others have suggested that the disease is caused by a more virulent, variant strain of dengue virus. Recent advances in molecular biology and hybridoma technology are providing valuable clues toward a solution and illustrating the fact that the course of a human viral disease is often a net (...) result of unseparated interactions between host and virus.
