‘100-day cough’ symptoms are important to recognise as cases of whooping cough are on the rise, with another baby succumbing to the illness. Whooping cough, also known as pertussis, can be severe and is characterised by prolonged coughing bouts. Symptoms typically start as a cold but progress to intense coughing spells, especially at night. The condition is most dangerous for babies, with over 300 infants under three months diagnosed in the first half of this year. Vaccination is key to prevention, with pregnant women urged to get vaccinated to protect their babies. The recent surge in cases is attributed to decreased immunity and vaccination rates, underscoring the importance of timely vaccination.
