months time, the length of time he was on board M/T Eastern Jewel before the symptoms became manifest.   It is of no moment that Masangcay passed his pre-employment medical examination. It is probable that the pre-employment medical examination conducted on him could not have divulged his illness for which he had been brought to the Fujairah Hospitalin the United Arab Emirates, considering the fact that most, if not all, of such medical examinations are not so exploratory.
