Is it a Cold or Flu?
Flu symptoms can often be confused with the common cold, but the flu usually comes on more suddenly and is more severe than the common cold.
Symptoms of flu may include fever (usually high), headache, tiredness and weakness (can be extreme), dry cough, sore throat, runny or stuffy nose, body or muscle aches, nausea, vomiting, and diarrhea (much more common among children than adults).
A person who is sick with the flu is contagious, meaning they can spread the virus. Adults can be contagious from one day before having symptoms to seven days after getting sick. Children can be contagious for even longer than seven days.
