Health officials in Fiji say seven people have died from leptospirosis since January and it is feared the disease was a factor in another 13 deaths.
The National adviser for Communicable Diseases says 279 people have contracted the infectious disease since the January floods and 85% are from the Western Division, Radio New Zealand International reports.
Mike Kama says those who died were adults, many of them farm workers.
Dr Kama says there has been no death from dengue fever or typhoid, the other communicable diseases plaguing the area after the floods.
