The number of people affected by chikungunya in Samoa has increased from 51 to 269 in the last two weeks.
The Ministry of Health Director General, Leausa Tole'afoa Dr Take Naseri, says an ongoing clean up and spraying of mosquito breeding sites is continuing with aircraft and ships being sprayed.
He says laboratory tests have shown two deaths thought to be caused by chikungunya were not.
3,000 people from around the world are expected in Apia from later this week week for a major UN conference, and the Ministry has said it hopes to have the outbreak under control by then.
