The goal of this observational study is to identify biomarkers and host factors associated with dengue severity in patients from dengue-endemic regions. The main question it aims to answer is:
Can multi-omics approaches predict disease severity and identify key factors contributing to severe dengue infections?
Participants will include individuals with dengue infection, and the study will analyze their blood samples using multi-omics techniques to uncover host immune responses, disease pathogenesis, and cellular pathway interactions. The study will also assess the role of primary and secondary infections, virus serotypes, and immunological factors in disease progression. Findings aim to support disease management, improve severity prediction, and identify potential therapeutic targets to prevent severe outcomes.

Inclusion Criteria:
Group 1: Dengue without warning signs Patients presenting with the following symptoms confirmed positive for dengue infection by lab diagnosis by anti-dengue IgM or NS1 ELISA will be recruited for the study under this cohort.
Symptoms will be fever along with at least two of the following -

* Persistent vomiting
* Fluid accumulation
* Mucosal bleeding
* Restlessness, lethargy
* Liver enlargement \>2cm
* Laboratory findings: An increase in hematocrit levels and a rapid decrease in platelet count Group 3: Severe dengue
* Severe plasma leakage leads to hypovolemic shock (dengue shock syndrome) and fluid accumulation with respiratory distress.
* Severe bleeding, such as epistaxis, internal bleeding, etc., is evaluated by a clinician.
* Severe organ involvement with any of the following symptoms
* Liver AST or ALT ≥ 1000

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
