Cold, cough and fever lasting two weeks, even with warm water for care, has gone past what a simple viral cold usually takes to clear on its own. This duration often means a secondary infection has set in, or another cause needs ruling out.
Next Steps
Please see a general physician this week for an examination and basic blood tests, and a chest check if the cough has thickened or won't let up.
Health Tips
Go in sooner if you develop breathlessness, a fever that won't settle, or you're unable to eat or drink enough.
