Buruli ulcer could spread as agriculture intensifies in Africa, making prevention research vital, says agro-eco-health expert Rousseau Djouaka.

Emerging resistance to artemisinin means efforts to track genetic markers and regulate the drug's use must step up, says Priya Shetty.

Africa's health research capacity is growing but needs a stronger workforce, say Carel IJsselmuiden and colleagues.

India urgently needs a permanent dengue surveillance system, say N. Sivagnaname and colleagues.

There is a pressing need for Africa to bolster its pharmaceuticals industry, and that requires the right policy framework, argues Priya Shetty.

Health systems in developing nations aren't ready for the diseases that accompany ageing, writes Priya Shetty.

Amanda Glassman director of Global Health Policy argues that a joined up approach is needed if mHealth is to transform health systems.

Healthcare policies and research strategies in developing countries must adapt to the new big killers, says Priya Shetty.

Health scientists in developing countries can use social media to tackle research priorities, argue Alexander E. T. Finlayson and colleagues.

Assessing each country's needs is key to ensuring that medical technologies fulfil their promise, say Sidhartha R. Sinha and Michele Barry.

Public health researchers must be sensitive to resource limitations to ensure medical innovations bring real benefits, says Takunda Matose.

Three key approaches could reduce the number of cholera cases and prevent diseases of poverty in Haiti, say experts in PLoS NTDS.

Vaccination campaigns to eradicate polio must change how they engage with local communities, say Heidi J. Larson and Isaac Ghinai.

Few causes are more worthy of funding than vaccines, says Priya Shetty, and the developing world relies on GAVI getting the billions it needs.
