Whooping cough causes intense coughing fits that can lead to vomiting, exhaustion, and breathing difficulties. It's most dangerous for infants and young children, and early treatment matters.
The early stages of whooping cough are similar to those of a common cold, which is why it's often diagnosed too late. Rarely will anybody go for a check-up because they have to sniffle and use tissues, but unfortunately, whooping cough will stay hidden without proper examination. A runny nose will last for a few weeks in those afflicted with whooping cough.
