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

Contrary to oft-repeated claims, climate change is unlikely to cause a major rise in malaria, says medical entomologist Paul Reiter.

Quickly detecting, not predicting, malaria epidemics is the key to disease control, says tropical medicine expert, Jonathan Cox.

We must prepare for climate change bringing more natural disasters that favour mosquito-borne disease, says Jai P. Narain from the WHO.

We must reduce the poor's vulnerability to insect-borne disease regardless of climate change, says public health expert Ulisses Confalonieri.

Reporting on how climate change affects health is a real challenge — screen your sources and find reliable experts, says Asefaw Getachew.

More research must be invested in controlling or preventing disease to reduce climate-related health risks, says Dziedzom De Souza.

Rising temperatures, which promote algal blooms and the spread of pathogens, are setting a new agenda for microbiologists, says Bernard Dixon.

A new WHO research agenda on climate change and health emphasises the importance of health issues in climate discussions, says The Lancet.

The health sector must more closely consider the effects of climate change, write A. J. McMichael and colleagues in the British Medical Journal.

Collecting comprehensive national and regional data could thwart the spread of malaria in Africa as conditions warm, argues Suad Sulaiman.
