What does the Greek certificate actually check for?
Someone asked us this week what the Greek certificate is actually checking for. It's a fair question, and most websites answer it with something vague about "diseases posing a public health risk". That phrase does come from somewhere specific, and once you see where, the whole thing makes a lot more sense, including why Greece asks for two tests that Spain doesn't.
Before we start: this article explains the paperwork behind visa medical certificates. It is not medical advice, and nothing here should be used to work out whether you personally have or don't have any condition. If you have a question about your own health, speak to your GP or another qualified clinician.
It isn't legal or immigration advice either, and the rules do change. Always check with the relevant embassy or consulate before you pay for anything.
The phrasing traces back to European law. An annex to a 1964 EU directive set out four categories of "diseases which might endanger public health", and two of them were named outright: active respiratory tuberculosis and syphilis.
The first category isn't vague either. It points at the WHO's International Sanitary Regulations of 1951, which name six diseases outright.
That is almost certainly why Greek consulates ask for tuberculosis evidence and a syphilis test result, while Spain, which points at a different and more modern instrument, asks for no tests at all.
Where the phrase comes from
Council Directive 64/221/EEC, dated 25 February 1964, dealt with when a country could refuse entry or residence on public health grounds. Rather than attempt an exhaustive list of conditions, which the directive itself acknowledged would be of little practical use, it grouped them into categories in an annex.
Under the heading "Diseases which might endanger public health", that annex listed four things.
The six quarantinable diseases
The first category in that annex refers to diseases subject to quarantine under the World Health Organisation's International Sanitary Regulations of 1951. Those regulations are a real, published document, and the UK's own treaty library holds the full text.
Article 1 defines the term plainly. The quarantinable diseases are:
- Plague
- Cholera
- Yellow fever
- Smallpox
- Typhus, meaning louse-borne typhus
- Relapsing fever, meaning louse-borne relapsing fever
Put that together with the other two named categories and you get the complete list that sits behind the phrase: those six, plus active respiratory tuberculosis, plus syphilis.
Read that list as history, not as a checklist. The 1951 regulations were superseded long ago, and smallpox was declared eradicated worldwide in 1980. Nobody is going to test you for six quarantinable diseases to issue a visa certificate.
What the list does is explain where the wording came from and why two conditions, tuberculosis and syphilis, ended up singled out in practice.
Why tuberculosis and syphilis specifically
This is the part that answers the original question.
Two of those four categories name a single condition each. Not a group, not a principle: tuberculosis of the respiratory system in an active state or showing a tendency to develop, and syphilis, listed on its own with no qualifying wording at all.
Everything else in the annex is framed as a category. Quarantinable diseases, defined by reference to the WHO's International Sanitary Regulations of 1951. Other infectious or contagious parasitic diseases, and only where the host country has protection provisions covering its own nationals.
So when a Greek consulate asks for a BCG record or chest X-ray plus a syphilis test result, it isn't an arbitrary pair. Those are the two conditions European law once named individually, and national practice has carried that forward.
An important caveat about the 1964 directive. It was repealed in 2004. Its successor, Directive 2004/38/EC, takes a different approach in Article 29: the only diseases justifying restrictions are those with epidemic potential as defined by the relevant World Health Organisation instruments, plus other infectious or contagious parasitic diseases where the host state has protection provisions for its own nationals.
So the older annex is the historical root of the wording rather than the law in force. It explains why the practice looks the way it does. It is not itself the current rule.
Why Spain and Greece ask for different things
Spain's certificate points at the International Health Regulations 2005, the modern WHO instrument. Those aren't a fixed list of named diseases. They're a framework for public health emergencies of international concern. That's why a Spanish certificate is a clinical judgement rather than a set of test results, and why no blood tests are required for it.
Greek practice for third-country nationals sits under Law 4251/2014, and in practice the consulates have kept the older, more specific framing. Hence documented evidence rather than a declaration.
Same broad idea, two different instruments, two very different documents to assemble.
What this means in practice
If you're applying for a Greek national long stay visa, the practical consequence of all this history is straightforward. You need the evidence in hand before the consultation, because a doctor can't produce a laboratory result during an appointment.
That's the single most common reason Greek applications get delayed: people book the consultation first, the way they would for Spain, and find there's nothing to attach the declaration to.
A note on what this article is not
We've written this because someone asked a specific question about the paperwork, and the answer turned out to be genuinely interesting.
What we haven't done, and won't, is tell you what any of this means for your own health. We don't know your history and this isn't the place for that conversation. If reading a list of conditions has raised a question for you, that's a conversation for your GP, and the NHS provides free and confidential testing for several of the conditions mentioned here.
What we can tell you is what the consulate wants on the paper.
Questions people ask us
Q Is there an official list of diseases for the Greek certificate?
Not a single definitive published list for applicants. The categories above are where the framing originates. What matters practically is the evidence your consulate asks you to supply.
Q Will I be tested for all of those diseases?
No. The list explains the origin of the wording. In practice Greek consulates ask for tuberculosis evidence and a syphilis test result, and Spain asks for no tests at all.
Q Why does Spain need no tests when Greece does?
They point at different instruments. Spain references the International Health Regulations 2005, which is a framework rather than a list. Greek practice retained the older, more specific approach.
Q Where do I get the tests done?
Syphilis testing is available free and confidentially through NHS sexual health clinics. For tuberculosis evidence, ask your consulate whether they want a BCG record or a chest X-ray before paying for either.
Q Does the 1964 directive still apply?
No. It was repealed in 2004. It's useful for understanding where the wording came from, not as a statement of current law.
Q Do short visits to Greece need any of this?
No. This applies to national long stay visas, not short Schengen visitor stays.
Q What if I have a question about my own health?
Speak to your GP. We can explain the certificate process, but your health is a conversation for a clinician who knows your history.
Please double check before you rely on this. Visa rules are set by foreign governments and their consulates, and they can change at any time without warning. Different consulates sometimes apply the same rules differently. Everything above reflects our understanding on the date shown at the top of this page.
This article is general information about the certificate process only. It is not medical advice, legal advice or immigration advice, and we are not immigration advisers. For anything concerning your own health, speak to your GP or another qualified clinician. For what your application requires, confirm directly with the authority handling it before you order anything or book travel.
