Once you become infected with whooping cough, it takes about seven to 10 days for signs and symptoms to appear, though it can sometimes take longer. They're usually mild at first and resemble those of a common cold:  Runny nose Nasal congestion Red, watery eyes Fever Cough  After a week or two, signs and symptoms worsen. Thick mucus accumulates inside your airways, causing uncontrollable coughing. Severe and prolonged coughing attacks may:  Provoke vomiting Result in a red or blue face Cause extreme fatigue End with a high-pitched "whoop" sound during the next breath of air  However, many people don't develop the characteristic whoop. Sometimes, a persistent hacking cough is the only sign that an adolescent or adult has whooping cough. Infants may not cough at all. Instead, they may struggle to breathe, or they may even temporarily stop breathing.
