Vietnam Health Declaration 2026: Does Decree 165/2026 Apply to You?

Short answer: not today. There is no health declaration form to fill in before your flight to Vietnam in September 2026, and there is no working government website to file it on. But the law that would let Vietnam demand one from you is already in force, and it covers every airport, land gate and seaport in the country.

That gap between what the law allows and what the Ministry of Health has actually switched on is where most of the internet has gone wrong this year. Plenty of sites are still telling travellers they must complete a health declaration within seven days of departure, some are selling "health declaration assistance" for a form that does not exist, and at least one is pointing people at a website the Ministry has explicitly abandoned.

Here is the version that matches the decree text and the Ministry's own statements, so you know what to check before you fly and what to ignore.

What Decree 165/2026 actually says

Decree 165/2026/ND-CP was signed on 15 May 2026 and took effect on 1 July 2026. It is the implementing decree for Vietnam's new Law on Disease Prevention, which the National Assembly passed in 2025 and which also came into force on 1 July. It replaced the old quarantine rules that had been patched together since the COVID years.

Article 22 is the one travellers care about. It has four clauses and they only make sense read together.

Clause 1 sets the headline obligation: anyone entering, exiting or transiting through Vietnam is required to make a health declaration as prescribed in the following clauses. On its own, that is the sentence every news agency quoted in May 2026, and it is why "mandatory health declaration for all travellers" went around the world.

Clause 2 is the part that got dropped from those headlines. It hands the actual trigger to the Minister of Health, who decides which groups of people and which time periods the requirement applies to at border gates, for each infectious disease, based on the global disease situation and the risk of that disease being introduced into Vietnam at any given moment.

In other words, Decree 165 does not create a standing form. It creates a standing power to require a form. The Ministry turns it on for a named disease, a named group and a named period, and turns it off again when the risk passes.

The remaining clauses cover mechanics. Declarations can be electronic or on paper, following Form No. 01 in Appendix V of the decree, and you can be asked to show proof of vaccination or prophylaxis where the Ministry requires it. The form is bilingual Vietnamese and English, with other languages possible at specific gates.

Why the "mandatory for all travellers" version was wrong

By the time the decree took effect, the Ministry of Health had gone public to correct the coverage. On 30 June 2026 the government portal carried a statement from Vo Hai Son, Deputy Director-General of the Department of Preventive Medicine, and it said the opposite of the headlines: the health declaration under Decree 165/2026 should not be understood as mandatory and routinely applicable to everyone entering, exiting or transiting Vietnam.

His reasoning, in plain terms: clause 2 of Article 22 puts the decision in the Minister's hands, per disease, so a blanket obligation from 1 July was never what the text described. If a declaration is introduced, it will come with guidance naming the disease, the travellers covered and the point of entry.

That statement has been reported by the Vietnam Government Portal in English and repeated by the Ministry's own channels and the consulate network. It is the most authoritative thing written on this topic, and it is the one that agency sites have been slowest to pick up, because "no form needed" sells less well than "new mandatory form".

Where the confusion comes from is worth knowing, because you will run into it again:

• Read clause 1, skip clause 2. This is the bulk of it. Xinhua, VOV and The Saigon Times all led with "mandatory from 1 July". Several never ran a correction.
• Corporate immigration alerts. EY, KPMG, Envoy and Vialto all published alerts in June and August 2026 headlining mandatory declarations. The KPMG alert is more careful than its title, hedging that travellers "may be required" to complete a declaration, but the title still does the damage.
• Framework read as mechanism. Vietnamese commercial sites such as vietnamprearrival describe the obligation as a permanent standing requirement you file within seven days of every crossing. There is no open system to file it through.

Even the UK's Foreign Office sits in the middle here. Its Vietnam entry requirements page says that from 1 July, if you travel to or transit through Vietnam you may be required to complete a health declaration which may include proof of vaccinations. "May be required" is the honest wording, and it matches the Ministry's position rather than the headlines.

tokhaiyte.vn is dead. Do not file there.

If you search "Vietnam health declaration" right now, the first thing you will find is the old COVID-era portal, tokhaiyte.vn. Ignore it.

The Ministry of Health stated plainly on 30 June 2026 that it no longer uses tokhaiyte.vn for health declarations by people entering, exiting or transiting Vietnam. The site has not been retired as a landing page, which is exactly why it keeps surfacing, but it is not the channel for Decree 165 declarations and anything you submit there goes nowhere useful.

The Ministry is building a new declaration system. When a declaration requirement is actually activated for a specific disease, that system will be announced and opened for public use. Until then, there is nothing to log into.

Two practical warnings follow from that.

Any website charging you a fee to "process" a Vietnam health declaration in 2026 is selling you a form that has not been activated. The declaration, when it exists, is free, and it is filed on a government system.

Do not hand your passport number, dates of travel and vaccination details to a third-party site that appears to be a government portal. The genuine declaration channel will be announced by the Ministry of Health or carried on the government portal, and it will not need a payment card.

When the requirement switches on, and who it would hit

As of 21 September 2026, no Ministry of Health guidance has been issued activating health declarations at border gates for any disease. Vietnam has had an active dengue season (more than 70,000 cases and 9 deaths in the first seven months of this year, with Ho Chi Minh City alone above 23,000) and a measles cluster in Dak Lak province, and neither has produced a border declaration notice. The mechanism is for diseases with cross-border introduction risk, which is a different calculation from domestic case counts.

If it does get activated, the shape is already visible in the decree, and it will not look like the 2020 version.

• It will be disease-specific. The guidance names one infectious disease, not "all arrivals". Expect something like a respiratory illness with pandemic potential, an outbreak in a neighbouring country, or a new variant with a specific geographic footprint.
• It will be time-bound. The Minister sets the period. Declarations get switched on for a defined window and switched off when the risk assessment changes.
• It will be group-specific. The guidance can cover travellers from certain countries, on certain routes, arriving at certain gates, rather than everyone on every flight. A blanket requirement is possible under the text, but the Ministry's own explanation repeatedly points at targeted application.
• Transit passengers are in scope. Article 22 covers people transiting Vietnam who never clear immigration, so a long layover at Tan Son Nhat or Noi Bai would not exempt you if a declaration were active. That is different from the digital arrival card, which does not apply to travellers who stay airside.
• Departures count too. The decree covers exit as well as entry, so a declaration activated mid-trip could catch you on the way out of the country, not just on the way in.

The form itself, if it is ever required

The declaration form is Form No. 01 in Appendix V of Decree 165/2026. It sits around page 96 to 100 of the signed decree PDF published on chinhphu.vn, printed in Vietnamese and English side by side. If other languages are needed at a particular border gate during an outbreak, the decree allows for them.

What it asks for is short and predictable: identity and passport details, your route and arrival or departure date, where you will stay in Vietnam, contact details inside the country, any countries or territories you visited in the previous 14 days, and a symptom checklist for that same period covering fever, cough, breathing difficulty, sore throat and vomiting. There is a truthfulness declaration at the bottom and a signature or electronic signature field.

Two details are worth remembering now, because they are the ones people get wrong on paper forms:

The window is seven days before the crossing. That is stated in clause 6 of Article 22 and it applies to entry, exit and transit alike. Seven days is the outer limit, so a declaration filed earlier than that is outside the window and would need redoing. It is also a much longer runway than the digital arrival card's 72 hours, which is a common source of muddle.

Dates go day first. Vietnamese forms use dd/mm/yyyy. If you are used to month-first, write the day first anyway.

Paper and electronic are both acceptable under the decree. A paper form means the version printed in the appendix, filled by hand, which is why airlines have historically handed them out on board. Electronic means the Ministry's own system, once it exists and once a requirement is live.

Health declaration vs the digital arrival card: two different forms

This is the single biggest source of confusion in 2026, because Vietnam has two separate pre-travel systems and only one of them is running.

The digital arrival card, officially the Pre-Arrival Information system, is an immigration form. It runs on the immigration department's own portal and is live at five airports: Tan Son Nhat since 15 April 2026, then Phu Quoc, Noi Bai, Da Nang and Cam Ranh. You file it inside 72 hours of arrival, get a QR code by email, and show it at passport control. It is free, it applies to foreign travellers including infants, and you do not file it if you are transiting without clearing immigration. Full walkthrough in our digital arrival card guide.

The health declaration under Decree 165 is a public health form. It covers air, land and sea crossings, both directions, with a seven-day window, and it is administered by the Ministry of Health rather than immigration. Right now it is dormant.

They do not replace each other and neither satisfies the other. If a health declaration is ever activated, a traveller landing at Tan Son Nhat or the other four airports would be looking at both forms, filed on two different government systems.

One ranking trap while you are here: several commercial sites still describe the arrival card as applying at Tan Son Nhat and Phu Quoc only, and one Chinese-language guide states the arrival card window is two days while the health declaration is seven. The airport list is out of date (Noi Bai, Da Nang and Cam Ranh were added in June 2026) and treating Decree 165 as a live filing obligation is the same clause-2 omission described above.

What happens at the border regardless

Health quarantine officers were already at Vietnamese border gates before Decree 165, and their powers are now written into Article 20 of the Law on Disease Prevention. None of this needs anything from you in advance.

Officers observe arriving and departing travellers directly and indirectly, and read body temperature with medical surveillance equipment. That is the routine layer, and it is the reason people sometimes describe "thermal screening" as if it were a formality. It is passive. You walk past it.

If something looks off, the decree sets out a second layer. The officer can check your travel documents, interview you, collect epidemiological information about where you have been and what preventive measures you took, and look for symptoms. If a person falls under the medical-handling provisions of the law, the officer applies them.

The one traveller-friendly number in the whole decree: once you are pulled for an on-site inspection, the process for that individual must be finished within two hours. That is a cap on the inspection, not on any treatment that follows.

Conveyances are covered too. Article 27 requires aircraft to submit a general declaration and a health inspection certification before entry, exit or transit, with separate forms for road and rail transport. Your airline handles that, not you, but it explains why a flight from an outbreak area can be met at the gate by a quarantine team.

Before you fly: a short checklist

1. Sort the visa, not the health form. That is what can actually stop you at the gate. Check whether your passport is on the 2026 visa exemption list and how many days you get, or apply for the 90-day e-visa. Requirements by nationality are broken down in the country-by-country guide.
2. File the digital arrival card if you are landing at Tan Son Nhat, Noi Bai, Da Nang, Cam Ranh or Phu Quoc, inside the 72-hour window. The steps are in our arrival card walkthrough, and the paper alternative is covered in the NA5 form guide.
3. Do not file a health declaration. There is nothing open to file on. Skip the paid "assistance" offers.
4. Save the form template anyway if you are crossing a land gate during a health scare. The paper version in Appendix V of the decree can be printed and carried, and a filled paper declaration presented to a quarantine officer is accepted under the decree if a requirement goes live while you are in transit.
5. Keep vaccination records accessible, not necessarily printed. If a declaration is activated for a specific disease, the Ministry can ask for proof of vaccination or prophylaxis, and a photo on your phone is enough for most situations.
6. Re-check 48 hours before departure. The trigger for activation is a Ministry announcement, and those arrive with days of notice rather than months. Decree 286/2026, which took effect on 15 September 2026, already tightened data sharing for e-visa holders and exempt entrants, so expect more of these moving parts rather than fewer.

If you are already in Vietnam and thinking about a border run to reset your stay, the visa run hub compares the land corridors, and HCMC visa runs and Da Nang visa runs handle the city desks.

Frequently asked questions

Do I need a health declaration to enter Vietnam right now? No. As of 21 September 2026 the Ministry of Health has not activated health declarations at border gates for any disease. There is no form to complete before you travel and none to complete on arrival.

Is Decree 165/2026/ND-CP in force? Yes. It was signed on 15 May 2026 and took effect on 1 July 2026 alongside the Law on Disease Prevention. What is not in force is an actual declaration requirement, because Article 22 clause 2 leaves that to the Minister of Health for each infectious disease.

Why do so many sites say it is mandatory for all travellers? Because they quoted clause 1 of Article 22 and stopped there. That clause says people entering, exiting or transiting are required to declare as prescribed, and clause 2 is where the prescription is defined. Most of those articles were written in May 2026, before the Ministry corrected the interpretation on 30 June.

Can I complete the declaration on tokhaiyte.vn? No. The Ministry of Health said on 30 June 2026 that it no longer uses tokhaiyte.vn for entry, exit or transit health declarations. A replacement system is being built and will be announced when a requirement is activated.

If a declaration is activated, how early do I file it? Within seven days before your entry, exit or transit through a Vietnamese border gate. That outer limit is set in Article 22 clause 6 and it applies in both directions, so a declaration filed eight days ahead falls outside the window.

Does it apply to transit passengers who stay airside? Under the decree, yes. Article 22 covers people transiting Vietnam, and a Ministry statement confirmed that transit passengers who do not clear immigration are not exempt. That is the opposite of the digital arrival card, which airside transit passengers do not file.
