Whooping cough (pertussis) also known as a Black cough, is a highly contagious respiratory tract infection. It's marked by a severe hacking cough followed by a high-pitched intake of breath that sounds like "whoop." Deaths associated with a whooping cough are rare but most commonly occur in infants. That's why it's so important for pregnant women — and other people who will have close contact with an infant — to take extra care.
