Influenza (flu) can cause mild to severe illness, and at times can lead to death. Flu is different from a cold. Flu usually comes on suddenly. People who have flu often feel some or all of these symptoms:
fever* or feeling feverish/chills
runny or stuffy nose
muscle or body aches
some people may have vomiting and diarrhea, though this is more common in children than adults.
*It’s important to note that not everyone with flu will have a fever.
The American food supply is among the safest in the world, but people can still get food poisoning by eating contaminated foods. Some food poisoning is caused by antibiotic-resistant bacteria. Symptoms of infection with antibiotic-resistant bacteria are like other food poisoning symptoms, which can be mild to life-threatening and include diarrhea, nausea, and vomiting.
