Dengue in the Marshall Islands — a newly detected outbreak. The Pacific Community (SPC) Pacific epidemic alerts map reports 8 cumulative dengue cases as of 21 August 2026, with no deaths, and classes transmission as increasing; the serotype is not yet determined. The WHO Western Pacific Dengue Situation Update #752 of 20 August 2026 independently notes that the first three cases in the Republic of the Marshall Islands were reported in epidemiological week 33 (10-16 August 2026), which is consistent with a small, recent and growing cluster. The case count itself rests on a single source and no national situation report has been published yet, so these figures are provisional. Source: Pacific Community (SPC) Pacific epidemic alerts map, 21 August 2026, with the existence of the outbreak corroborated by WHO WPRO Dengue Situation Update #752.
