A 7-year-old boy has died after swallowing a button battery while on holiday with his family.
The seven-year-old, who lived in Payerne, Switzerland, named in reports as Jose, was on holiday in Portugal when he swallowed the battery.
The victim was taken to a hospital in the city of Coimbra and the battery was removed, but he later died of vasculitis, an inflammation of the blood vessels.
He reportedly swallowed the battery around Christmas time and died on January 14th.
Swiss authorities report that in most cases of button battery ingestion, the objects pass through the body and are eliminated in the feces 24 to 96 hours later.
Eighty to 95 percent of those affected show no symptoms. However, in rare cases, it can have serious or fatal consequences.
Complications include damage to the esophageal mucosa or even perforation of the esophagus.
