Before, on March 28, a man went to jungle picking up mushroom to cook soup for the lunch.
Until the late afternoon on the same day, four family members including the man, his wife, his son and his daughter-in-law experienced headache, dizzy, diarrhea; they were taken to the local hospital for emergency treatment next morning when they were in critical condition.
Because of bad poisoning, the man’s son and the wife died on March 31 and April 1.
Next, the daughter-in-law couldn’t survive meanwhile the man was in critical condition; hence, he was transferred to Bach Mai Hospital for further treatment.
