False. Anaphylaxis typically involves more than one symptom in more than one part of the
body at the same time. For instance, a serious reaction could involve developing a rash and
vomiting or diarrhea after being exposed to an allergen. Other warning signs of a serious

Swollen throat or swollen areas of the body
Wheezing
