•Main coughing stage
After several days, often as many as 10-14 days from the start of the illness, the cough gets worse and worse. They are sometimes called choking coughs.
• During a bout of coughing, you repeatedly cough over and over again. The face often goes red and the body becomes tense. Eventually, there is a desperate attempt to breathe in, which may cause a whooping sound.
• Some children may stop breathing at the end of a bout of coughing and go blue for a short time. This looks worse than it actually is, as breathing usually quickly resumes. Sometimes, it they can’t breathe in, they will died.
• It is common to vomit at the end of a bout of coughing.
• The number of coughing bouts per day varies from case to case. You may only have a few bouts each day but some people have up to 100 bouts per day. The average is about 12-15 bouts per day.
