The Ministry for Health has reported seven cases of Zika in the Kingdom of Tonga.
Health officer Mrs Sela Fa‘u told Radio 87.5FM that a record 259 people sought medical advice for signs and symptoms of the zika virus at Vaiola Hospital.
Mrs Fa’u said only 7 of the 259 were confirmed to carry the zika virus.
Three of the people diagnosed are pregnant women.
Researchers in Brazil, where zika was first detected in May, have linked infections in pregnant women to a condition known as microcephaly:
infants born with undersize heads.
Meanwhile, the Ministry of Health, Tonga Red Cross Society and His Majesty’s Army are working together to remove all rubbish in the villages and destroy mosquito breeding spots in schools.
According to Mrs Fa‘u, they have completed spraying most of the primary and high schools.
The spraying campaign is being held in pre-schools and it is expected to end next week.
The Ministry of Health is also advising the public to take precautions by using mosquito repellents, mosquito nets and destroying all mosquito breeding places.
