A 15-year-old girl is dead after kissing her boyfriend. The teen, who is allergic to peanuts, unknowingly kissed her boyfriend who had just eaten a peanut butter snack.

Christina Desforges died in a Quebec hospital Wednesday after doctors were unable to treat her allergic reaction to the kiss the previous weekend.

Hospital officials report Desforges was almost immediately given a shot of adrenaline, a standard tool for treating the anaphylactic shock brought on by a peanut allergy.

An autopsy is being performed. Dr. Nina Verreault, an allergist at the Chicoutimi Hospital in Saguenay, declined to comment on the case.

The symptoms of peanut allergy can include hives, plunging blood pressure and swelling of the face and throat, which can block breathing.
