Household Clustering Suggests a Novel Chemoprophylaxis Trial Design for an Arboviral Disease

Chikungunya virus, which is transmitted by mosquitoes, can cause disabling chronic arthritis. There are currently no medicines for prophylaxis of Chikungunya, or other viruses transmitted by Aedes mosquitoes, such as Dengue and Zika. Potential therapeutics have been identified, but to perform a successful chemoprophylaxis trial during a short Chikungunya outbreak requires an identified at-risk population. We examined the potential for application of a household transmission model, as used in testing prophylactic drugs against respiratory viruses, included influenza and COVID-19.

In this poster we:

  • Set out the evidence for multiple Chikungunya infections occurring per household
  • Describe how we are validating the secondary household infection rate
  • Show how this could be used in future clinical trials to demonstrate prophylactic efficacy against chikungunya virus infection and other Aedes-mosquito-borne viruses
