Essential answer

Find official guidance is part of the Center’s possible recent exposure record.

A possible recent exposure can require time-sensitive assessment. This website does not collect exposure details or determine individual eligibility for testing or PEP.

Complete public explanation

Time-sensitive professional assessment may be appropriate after a possible recent exposure.

Use the information with its source date, population and jurisdiction. A general explanation cannot determine an individual’s diagnosis, eligibility, regimen or legal obligations.

Key considerations

  • Contact an authorized local service promptly.
  • PEP should be started as soon as possible when indicated and no later than 72 hours under current guidance.
  • Testing type and timing depend on the exposure and local protocol.
  • Do not delay care while trying to calculate risk online.

Research and evidence questions

01Which access models reduce delays to PEP?
02How can emergency, pharmacy and community pathways coordinate?
03Which testing strategies best detect acute infection?
04How can services collect only necessary sensitive information?
