Which Countries Require a Rabies Titer
Key takeaways
- 0.5 IU/mL is CDC's mark for an adequate response, not a list of countries.
- APHIS country pages say whether a titer is required.
- The detailed test page stays the rabies titre guide.
Which countries require a rabies titer is a destination question, not a single CDC list. CDC, checked on 14 November 2026, says a result at or above 0.5 IU/mL is evidence of an adequate immune response, and that FAVN and RFFIT are the tests it accepts. CDC does not publish one waiting period or one country list on that page.
Use the APHIS pet-travel tool for the country you are entering. APHIS pages for Taiwan and China, read the same day, each require at least 0.5 IU/mL and name the laboratories they accept. The timing is different on those two pages, so it is not repeated here as a general rule. The test itself, and what it cannot tell you, is on the rabies titre guide.
FAQ
- Does every country require a rabies titer?
- No. CDC describes the test and the 0.5 IU/mL mark. The destination decides whether you need it. Check that country's APHIS page.
- Where is the full explanation of FAVN?
- On the rabies titre guide. This page only points to it.
