Ethics approval and consent to participate
: Serum samples used in this study were provided from individuals in the Philippines and Vietnam. In the Philippines, suspected dengue patients provided single serum samples for the purposes of ongoing national dengue laboratory surveillance. Local ethics was awarded to the Research Institute for Tropical Medicine (RITM) (Ref: 2017-014) and London School of Hygiene and Tropical Medicine (LSHTM) Ethics Committee (Ref: 17965 and 15849) for the anonymous use of these samples for laboratory analysis. In Vietnam, paired sera were collected approximately 4 weeks apart from study participants following enrolment into a research project investigating the occurrence of dengue. Local ethical approval was obtained in Vietnam and by Nagasaki University (Ref: VN01057) and approved by LSHTM (Ref: 17853). Study participants over 18 years gave informed consent for laboratory/surveillance analysis of sera, while parental/guardian consent, coupled with minor assent, was acquired for those under 18 years prior to data collection. All unique participant identifiers were removed before data acquisition.
