Medical Test conditions in UAE (Dubai)

Hi everyone,

I am new to this forum, a friend of mine is currently doing a medical test for a company based in UAE, he has a history of dengue fever which happened I think around Protected content back, since then he has been in the UK.

I have read various medical test requirements set by UAE for entry and there is no mention about whether he be deported or will he lose his job offer if he has this history of dengue fever. I am not able to find any answer what is expected. It be really useful if you could provide some reply if you know someone with a similar experience or you yourself were in this position ( especially it is to do with dengue fever)?

Thanks
Akash
