How long does it take for a cold to turn into pneumonia?

A cold can potentially lead to pneumonia if the viral infection weakens the immune system or causes complications, but this process can vary significantly among individuals. Generally, pneumonia may develop within a week or two following the onset of cold symptoms, especially if the cold worsens or is not properly managed. However, not everyone who has a cold will develop pneumonia. It's important to monitor symptoms and seek medical attention if they worsen.
