SCIENTISTS are racing to find a treatment, health crews are scrubbing everything from money to buses, and quarantines are being enforced as the world battles the spread of coronavirus.

Concern is also growing over the economic fallout of the outbreak, with work at many factories halted, trade routes frozen and tourism crippled, while a growing list of countries brace for the illness to claim new territory.
