On the other hand, most studies concluding that climate change is indeed playing a role in highland malaria tend to be statistically strong, Chaves and Koenraadt found.

But, researchers said that just because climate is one factor influencing malaria's spread does not mean it is the only one. They said that they need a research approach that combines climate with other possible factors.

"Even if trends in temperature are very small, organisms can amplify such small changes and that could cause an increase parasite transmission. More biological data will improve our overall understanding of malaria and will allow scientists to propose more general and accurate models on the impacts of climate change on malaria transmission," said Chaves.

The authors cite numerous factors that could interact with climate to influence malaria spread.

They point to research showing that people migrating from lowlands may be introducing the malaria parasite into highland regions.

Changes in farming practices may also play a role. Irrigation associated with more intensive farming may be creating more places for mosquitoes to breed.

The study has been published in The Quarterly Review of Biology.
