Health officials in the Cook Islands are confident that an outbreak of dengue, which has affected over 700 people, is on the decline.
Dengue is a tropical disease that is transmitted by mosquitoes.
A medical officer, Dr Henry Tikaka, says health officials are confident the worst is over.
"For the month of April it has been a dramatic fall in a number of cases. We can see that in the number of cases we are seeing in the moment there are really sporadic cases, so we really hope that the trend will go right down and then disappear completely."
Heavy rain in the region since the beginning of the year has increased the number of mosquito breeding grounds and is thought to be the main reason for the increase in the infection rate.
