Health officials in Tonga have warned people to take extra hygiene precautions after more than 500 people in Tongatapu were diagnosed with conjunctivitis since March.
The highly infectious eye condition has mainly affected both infants and adults.
Medical Officers have been alerted to the viral infection and according to reports more than 200 cases had been registered this month.
People are being told to use separate towels and to wash their hands often.
Officials said the condition was highly infectious and passes very easily within families and between friends.
It causes a red watery eye with discomfort and blurred vision. In a few cases the discomfort can be severe.
