Head cold: An average head cold, which is a viral upper respiratory tract infection, lasts about a week and lethargy is common. Taking extra vitamin C at the first sign of a cold may help minimize symptoms and their duration. If symptoms and congestion last longer than a week, antibiotics may be needed.
