Verify whether your arrival country requires a Yellow Fever International Certificate of Vaccination based on your origin, transit duration, and days elapsed since your shot.
Select whether your itinerary includes departure or >12-hour transit in a WHO Yellow Fever zone.
Select the destination border where you will clear immigration and Port Health.
ICVP certificate becomes valid 10 days after shot
Arriving from or transiting >12h in an endemic zone triggers mandatory Yellow Card verification at Port Health Control (e.g., Bangkok BKK Health Control / Singapore ICA). At 15 days post-vaccination, your certificate satisfies the 10-day WHO activation window and holds lifetime validity.
Embassy-compliant GDS flight reservations, confirmed hotel bookings, and custom visa documentation packages without risking non-refundable tickets.
Yellow Fever border enforcement isn’t designed to protect you—it’s designed to prevent travelers arriving from South America or Sub-Saharan Africa from introducing the virus into Aedes mosquito populations in Asia and other regions.
How major destination hubs screen travelers arriving from South America & Sub-Saharan Africa
| Destination Hub | Endemic Transit Trigger | 10-Day Rule Enforcement | Penalty Without Valid ICVP |
|---|---|---|---|
| Thailand (BKK / DMK / HKT) | Departure or >12h transit in 42 listed endemic nations | Strict check at Health Control Desk before Immigration | On-site vaccination + medical observation fee or denied entry |
| Singapore (SIN) & Malaysia (KUL) | Origin or >12h layover in endemic Africa/LatAm | Strict airline check-in & ICA arrival screening | Up to 6 days quarantine at traveler’s expense or refusal of entry |
| India (DEL / BOM / BLR) | ANY transit in endemic zone (even <12 hours) | Zero tolerance; must be ≥10 days old on arrival | Mandatory quarantine in designated APHO hospital for up to 6 days |
| South Africa (JNB / CPT) | Origin or >12h transit in endemic African/LatAm states | Inspected prior to biometric passport booths | Denied boarding by airline or refusal of entry at Port Health |
| Australia (SYD / MEL / BNE) | Stay or >12h transit within 6 days before arrival | Verified by Australian Border Force (ABF) | Biosecurity interview, health monitoring, and entry delay |
No. Under WHO International Health Regulations (Annex 6), only the original physical yellow paper booklet bearing the wet-ink signature of the clinician and the official stamp of an approved vaccination center is legally valid.
Your ICVP remains valid for life even if the passport number written on it belongs to an expired passport. Simply carry a photo of your old passport bio page or the old passport itself so the name and date of birth can be cross-verified.
While Buenos Aires is non-endemic, Peru and Brazil are classified as endemic countries on almost all Asian and African Port Health lists. Even if you stayed in high-altitude Cusco where mosquitoes do not live, Thailand and Singapore require an ICVP simply because your passport shows departure from Peru.
Before you join the main Immigration queue at BKK, you must stop at the clearly marked "Health Control" counter along the arrival concourse, fill out the T.8 health declaration form, and get your boarding pass stamped by the Port Health officer.
