TLDR : Answer Summary

The health declaration is relevant only if you are traveling from a country that requires a yellow fever vaccine. If you are not coming from one of those countries, you do not need to fill out the health declaration form. When required, the process involves filling out a form that includes your travel origin and details about your flight into Thailand. It's essential to consult the official Thai immigration website for accurate information.

Are you in, or travelling from, one of the countries that are flagged for yellow fever? If not, then you don't put anything because it's irrelevant to you. Make sure you're on the Thai official page for the free arrival card.

Only if you come from a country on yellow fever list. I clarified it with officer when i came in last week. You fill the form it asks for origin of travel and then the flight you entered Thailand. Then you go to the desk and they double check your certification and record your seat number in case any outbreak. BUT only if yoir original flight is from a country on that list

crikey if filling in a TDAC is stressful then I wouldn't come to thailand. Just go with the flow and dont worry, when you do fill it out just fill in the details that are mandatory those with an *. Ignore the rest

Unless you're coming from a country that requires a yellow fever vaccine or some other health requirement, that part doesn't apply to you.

coming from the USA so it will let you process it without providing any info on the health declaration?

don't you think there would be a lot more posts about people having problems if there were a problem? Have you even opened the actual form yet?
