After recovering from whooping cough, patients usually produce antibodies in their bodies, so recurrences are rare. However, some patients may have weak constitutions, low immunity, and poor resistance. If they do not generate enough antibodies after being sick, they may get infected again when exposed to someone with whooping cough, leading to a second onset of the disease. If whooping cough recurs, the treatment plan is exactly the same as for the first occurrence, but patients should focus on boosting their immune system and resistance during treatment. In daily life, it is beneficial to eat foods rich in high-quality proteins and vitamins and to persist in physical exercise regularly.
