**The main extra precaution is preventing sexual transmission to your girlfriend.** Zika can spread through sex even if you feel completely well.

One timing clarification: the Puerto Rico outbreak and Miami coverage you describe sound like the **2016 outbreak**. For a trip now, use current guidance: CDC lists Puerto Rico as having current or past transmission, with no active Zika travel notice for Puerto Rico on its current risk page. That classification still warrants precautions. [CDC risk guidance](https://www.cdc.gov/zika/geo/)

For your trip and return:

- **Use condoms or abstain from sex for at least three months after returning**, even if you have no symptoms. This applies to vaginal, anal, and oral sex. If you develop symptoms or receive a Zika diagnosis, count the interval from symptom onset or diagnosis. Testing cannot reliably establish that you are safe to transmit no virus through sex. [CDC prevention guidance](https://www.cdc.gov/zika/prevention/index.html)
- **If your girlfriend is pregnant, use condoms or abstain throughout the pregnancy.** If you are planning pregnancy, discuss the trip with a clinician beforehand and wait at least three months after your return before trying to conceive. Infection during pregnancy can cause serious birth defects. [CDC travel guidance](https://wwwnc.cdc.gov/travel/notices/alert/zika-virus-puerto-rico)
- **Continue preventing mosquito bites for three weeks after returning.** This helps prevent an infected traveler from passing the virus to local mosquitoes. During your stay, screened or air-conditioned accommodation adds protection; mosquitoes can bite during both day and night. [CDC prevention guidance](https://www.cdc.gov/zika/prevention/index.html)

**A routine doctor visit or Zika test after travel generally isn’t needed if you remain well.** CDC recommends against testing asymptomatic, nonpregnant people. Seek medical advice if you develop fever, rash, joint pain, or red eyes during or after the trip, and mention your travel dates. Similar symptoms can come from dengue, which also needs consideration. Avoid aspirin and ibuprofen for such an illness until dengue has been ruled out.

**You should not expect special Zika testing or clearance to fly home.** CDC’s archived airline guidance explicitly states that suspected or confirmed Zika does not carry flight restrictions and that ordinary procedures for reporting ill passengers apply. That guidance was last reviewed in 2019. [CDC airline guidance](https://archive.cdc.gov/www_cdc_gov/quarantine/air/managing-sick-travelers/commercial-aircraft/zika-qa.html)
