Whooping cough cases have exploded since 2023, new CDC data shows

In the United States, whooping cough cases have surged significantly during 2023, with reported cases reaching 18,506 by October 12. This marks a fivefold increase compared to the 3,382 cases reported at the same time in the previous year. Whooping cough, or pertussis, is a highly contagious respiratory infection that can present symptoms similar to other respiratory illnesses, complicating its diagnosis. The initial symptoms often include a runny nose, low-grade fever, and a tickly cough, which progresses to severe coughing fits characterized by gasping for breath. Young children, especially those under one year old, face increased risks due to their developing immune systems, particularly if they have not received all recommended vaccinations. Infants are less likely to exhibit the classic cough, making it challenging to recognize the infection early. Complications such as pneumonia and, in rare instances, encephalopathy may arise, reinforcing the need for careful monitoring of young children and those unvaccinated. Whooping cough spreads through airborne bacteria, commonly transmitted in environments such as schools and childcare facilities. As the infection can be contagious for up to two weeks, families must be vigilant in preventing the spread among vulnerable populations. Treatment is most effective when initiated during the early stages; otherwise, management focuses on comfort care and hydration during the illness's duration. This surge in cases highlights the ongoing public health challenge posed by whooping cough and underscores the importance of vaccination to curb its spread.
