Myth-Busting – Cold vs Flu vs Pneumonia
Myth #1: “It’s just a bad cold.”
👉 Reality:
A cold usually causes a runny nose, sore throat, and mild cough. It can last 2-3 weeks.
Influenza (the flu) hits harder and faster: fever, body aches, headache, extreme fatigue.
Pneumonia is an infection of the lungs and can be serious or life-threatening.
Myth #2: “If I have a fever, and green phlegm, I must need antibiotics.”
👉 Reality:
Colds and flu are viral → antibiotics do not help. Color of mucus doesn't matter.
Pneumonia may be bacterial or viral → some cases require antibiotics, but this needs a medical assessment.
Myth #3: “The flu is just a worse cold.”
👉 Reality:
The flu is sudden and severe, often putting people in bed for days.
It can lead to serious complications requiring hospitalization like pneumonia, especially in older adults, children, pregnant patients, and those with chronic conditions. Luckily, most can be prevented by a flu shot.
Myth #4: “If I can breathe, it can’t be pneumonia.”
👉 Reality:
Pneumonia can cause persistent high fever, loss of appetite and energy, shortness of breath, chest pain, rapid breathing, and worsening cough. If you have these symptoms, call us for a same day, in person examination.
