If someone is slapped with something, it means they are suddenly and unexpectedly afflicted by it - here - the man is being slapped with a terrible illness, whereas the contradictory statement is saying he was uneffected by the illness.
Context: He was unaffected by a terrible illness for several months but still died later.
Hypothesis: He was slapped with a terrible illness that killed him quickly.

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
