A multi-agency effort is being launched by the Marshall Islands government to reduce the rates of chikungunya in the country.
The effort, involving the health ministry, public works and utility companies, will involve spraying mosquito breeding areas around Majuro Atoll.
The number of cases on Majuro has been steadily rising since chikungunya was first identified in February, the first known outbreak of the virus in the country.
The illness produces flu-like symptoms, including joint pain, fever, head and muscle aches.
