The threat of the potentially fatal diseases typhoid, leptospirosis and dengue fever has spread to Fiji's main island while the whole of Vanua Levu and Taveuni are already at high risk.
There have been 19 confirmed cases of typhoid within 30 kilometres of Suva while four have been reported from Qauia village close to the capital.
In the north which includes Vanua Levu and Taveuni there have been 77 confirmed cases of typhoid, 34 of dengue fever and 22 of leptospirosis.
The Fiji Sun newspaper reports that the Wailevu Primary School in Vanua Levu is closed with its head teacher in critical condition in hospital while two other teachers and six students have confirmed cases of typhoid.
One teacher died of the disease last week.
Fiji's acting director of public health, Dr Josaia Samuela, says the school will not re-open until water and toilet facilities are in good condition because otherwise the situation will only worsen and more people will become sick.
Dr Samuela says typhoid is endemic in Fiji and is constantly present in the population.
