-Children 1 to 9 yrs most affected
BY LORETTA B MANELE
The number of official cases has risen to 3,000 as the diarrhoea outbreak reportedly spreads across the country.
Ministry of Health and Medical Services (MHMS) says although Honiara and Guadalcanal remain the hotspots, clusters have been identified in Gizo and Helena Goldie hospital in the Western province, Auki in Malaita province, and Buala in Isabel province.
While no deaths have been reported, MHMS urges the public to remain vigilant and to continue practising good hygiene.
“Over 3,000 cases have now been recorded since the start of the outbreak. Although most cases are concentrated in Honiara and Guadalcanal, recent clusters have also been identified in Gizo, Auki, Buala, and Helena Goldie Hospital (HGH), indicating spread to other provinces,” a MHMS statement on Wednesday, July 23, 2025 said.
Children aged one to nine years remain the most affected.
The Ministry’s Health Information System (HIS) team is currently reviewing data to determine any diarrhoea-related fatalities over the past two months.
As of July 11, 12 out of 23 stool samples tested positive for rotavirus using rapid diagnostic tests (RDT), the statement said.
Further testing of samples that have been sent to the reference laboratory in Australia aims at precisely characterising the causative pathogen of the outbreak.
MHMS announced the diarrhoea outbreak on July 3, following a number of cases. A week prior, the ministry also announced the detection of the rotavirus in cases presented at the national referral hospital.
Rotavirus is associated with diarrhoeal conditions.
Health response interventions intensify
The NRH Emergency Department remains on alert, supported by the Paediatrics Clinical team. ORS (Oral Rehydration Salt) requests for supply have been reported and are being urgently addressed by the National Medical Stores and Second Level Medical Stores throughout the country. Meanwhile, paediatric teams are extending support through outreach to Guadalcanal, Malaita and other provinces.
Environmental Health and mobile teams in Honiara are also visiting communities, with plans to increase frequency to affected communities. Sanitation assessments are also being prepared, and cleaners in Honiara City Council clinics are undergoing refresher training on Infection, Prevention and Control (IPC).
Risk communication teams have begun reaching schools with key hygiene messages and plan to scale up outreach, through radio talkback shows, posters, and community visits. School messaging will also be included in all media and public materials going forward noting the commencement of the schools after the mid-year holidays.
Data mapping has shown rising case numbers in East and West Honiara.
