The boy had been confined for a week at the Tupua Tamasese Meaole Hospital at Motootua isolation unit for patients suspected of having measles.
He died on White Sunday.
The mother told the Samoa Observer that her son was first admitted last Monday.
The Ministry of Health Assistant Chief Executive Officer, Tagaloa Robert Thomsen, said the Ministry could not confirm the cause of the child's death, or even if the child was infected with measles until conclusive testing had been completed.
