Research suggests malaria can be defeated without a globally led eradication programPosted: February 26, 2013
“Our findings suggest it may be possible for malaria elimination to proceed like a ratchet, tightening the grip on the disease region-by-region, country-by-country, until eradication is ultimately achieved – but without the need for a globally coordinated campaign.”
The research team examined data from 1980 onwards for 30 countries which successfully eliminated malaria and also took part in the 1955 Global Malaria Eradication Programme (GMEP). In these countries, elimination has become highly stable, transmission (or infection) has declined and resurgence has occurred far less frequently than traditional theory would predict.
Three potential reasons for this decline and stability of malaria have been suggested:
declines in transmission rates resulting from urbanization and economic development
a high-degree of transmission control from treating malaria cases combined with outbreak control
low-connectivity among places that are highly receptive to transmission
