CDC's Draft Interim Response Plan for Zika


The CDC has published a 58-page PDF file on their Draft Interim Response Plan for Zika  Given the size and scope of this document, I've only reproduced the introduction:

Interim CDC Zika Response Plan (CONUS and Hawaii) Overview:

Initial Response to Zika Virus Infections
The purpose of this document is to describe the Centers for Disease Control and Prevention (CDC) response plan for the first locally acquired cases of Zika virus infection in the continental United States and Hawaii. The Zika virus is spread to people primarily through the bite of an infected Aedes aegypti or Aedes albopictus mosquito.
The response activities outlined in this plan are based on currently available knowledge about Zika virus and its transmission, and these activities may change as more is learned about Zika virus infection. Most of the plan focuses on response activities that would occur after locally acquired Zika virus transmission has been identified. CDC also is committed to responding to travel-associated and sexually transmitted Zika virus infections reported in the United States (US) before detection of the first locally transmitted case of Zika virus infection.

Planning Assumptions
Travel-associated and sexually transmitted Zika virus infections will continue to occur. CDC anticipates that local summer transmission may occur in limited areas of the continental United States (CONUS) and Hawaii where competent mosquito vectors exist.
  •  Because of the risk of transmission of Zika virus infection through blood transfusions, blood safety interventions are needed for both unaffected and affected areas. With the recent outbreaks in the Americas, the number of Zika virus infections among travelers visiting or returning to the United States is likely to increase.
  • Local transmission of Zika virus in US territories and affiliated Pacific Island countries is ongoing.
  • Neither vaccines nor proven clinical treatments are expected to be available to treat or prevent
  • Zika virus infections before local transmission begins within CONUS or Hawaii.

The efficacy of vector control in reducing mosquito-borne infection risks may be limited, as has been the case with similar mosquito-borne viruses, such as dengue and chikungunya.

CDC supports state and local efforts to prepare and respond to Zika virus. CDC guidance to state and local jurisdictions recommends that Zika action plans be developed to guide response activities through a phased, risk-based continuum. The continuum includes support for mosquito season preparedness and then graduated action in response to detection of:

  • The first limited local transmission
  • Widespread local and continuous transmission
  • Widespread, multicounty, continuous transmission

CDC and partners will support and assist states in the key activity areas listed below as different stages in this continuum are reached.
