Brief Summary
To evaluate the effectiveness of candidate dengue vaccine formulations, it is prudent to develop an appropriate challenge model. This study supports the expansion of the data set of the current Dengue 1 Live Virus Human Challenge (DENV-1-LVHC) model to produce uncomplicated dengue-like illness.

Eligibility Criteria
You may qualify if:
- Age 18-45 at the time of consent
- Ability and willingness to sign informed consent
- Passing score on comprehension test of at least 75%, with up to 3 attempts
- Available for the study period
- Willing to use contraception for the duration of the study
- Provide consent for release of medical history records from primary care physician, college or university, urgent care or emergency room visit
You may not qualify if:
- Female: pregnant or lactating
- Heavy menstrual bleeding within the last 6 months- menstrual periods lasting longer than 6 days, or requiring 5 or more pads or tampons per day.
- Female subjects using an intrauterine device (IUD) or Mirena®
- Female subjects with fibroids or uterine polyps, endometriosis, adenomyosis, and uterine scarring (e.g., after D\&C)
- Blood tests confirming infection with human immunodeficiency virus- 1 (HIV-1), hepatitis C, hepatitis B (assessed by HbsAg) virus, or positive antibodies to the flaviviruses (FV) dengue, West Nile, Yellow Fever, Japanese encephalitis, or Zika.
- Active Diabetes or active peptic ulcer disease (PUD)
- Chronic obstructive pulmonary disease (COPD) or coronary artery disease (CAD)
- Known or suspected congenital or acquired immunodeficiency; or receipt of immunomodulation therapy such as anti-cancer chemotherapy or radiation therapy; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
- Current, or a history of, auto-immune disease
- History of Guillain-Barré syndrome (GBS)
- Any history of FV infection or FV vaccination; or planned FV vaccination, outside the study protocol, during the study period
- Diagnosis with Bipolar Disorder or Schizophrenia, hospitalization in the past year for a mental health disorder, or any other psychiatric condition, which in the opinion of the investigator prevents the subject from participating in the study.
- Planned travel during the study period (180 days) which would interfere with the ability to complete all study visits
- Recent (in the past 4 weeks) travel to any dengue endemic area. These potential subjects may be eligible for enrollment a minimum of 4 weeks later
- Subjects with the following grade 1 or greater lab abnormalities: Creatinine; Liver Function Tests - ALT, AST; Hemoglobin (females and males); White Blood Cell (WBC) decrease; Platelets decreased; Prothrombin Time (PT); Partial Thromboplastin Time (PTT); Fibrinogen decrease
