Scientists track parasites with satellites

MELBOURNE: Scientists are using satellite data to help predict patterns of deadly parasitic diseases such as malaria.

The research could help authorities in developing countries fight parasitic diseases, according to Project leader Professor Archie Clements from the Australian National University.

"Some diseases are highly sensitive to their environment, especially parasitic diseases. With remote sensing you can identify places where disease flourishes," said Clements, Director of the ANU Research School of Population Health.

"This information is useful for decision makers to help them ensure scarce resources are targeted to where they are most needed," Clements said.

The team uses satellite data such as temperature, rainfall, vegetation and land usage, and combines it with health data in a geographical information system (GIS).

"The result is maps that are accessible to countries with limited capacity for managing disease data, tailored to their local needs," Clements said.

The team has trialled systems for malaria in Bhutan, Vanuatu and the Solomon Islands and is now seeking support to scale up to larger countries.

Additionally, spatial predictions for other diseases such as worms and hydatids (a serious and potentially fatal disease caused by a type of tapeworm) are being developed for China, the Philippines and other countries in the Asia-Pacific region.

The research was presented at a meeting of the American Association for the Advancement of Science Conference in San Jose, California.
