Chapter 01 — Health & Wellness
What's the difference between a cold and the flu?
Colds creep in over days with a runny nose and sore throat. Flu arrives in hours with fever, chills, and aching muscles. If you can still go to work, it's probably a cold.
Follow-up questions
When should I see a doctor?
Fever over 39 °C lasting more than 3 days, trouble breathing, chest pain, or symptoms that suddenly worsen after improving.
Do antibiotics help?
No. Both are viral. Antibiotics only matter if a bacterial complication (sinusitis, pneumonia) sets in.
Does vitamin C prevent colds?
It doesn't prevent them but may shorten them by about a day if taken regularly.
