The pertussis vaccine we currently administer is a combination vaccine that primarily includes diphtheria, pertussis (whooping cough), and tetanus, commonly referred to as the DTP vaccine. It is generally administered for the first time when a baby is three months old, the second dose at four months of age, and the third dose at five months. A booster vaccine is given again when the child is one and a half to two years old to produce antibodies that can effectively prevent pertussis, a respiratory infectious disease. It is important to detect early, vaccinate in a timely manner, and prevent early.

Whooping cough belongs to which type of infectious disease?

Pertussis, also known as whooping cough, is an acute respiratory infectious disease caused by the infection of Bordetella pertussis. It is categorized as a Class B infectious disease according to national regulations. Bordetella pertussis has weak resistance to external environments and is generally not considered to spread through indirect contact. The primary mode of transmission is through respiratory droplets. Asymptomatic infected children are the main transmitters of the disease. Children under the age of five are the most susceptible. Babies typically receive their primary immunization at the ages of 3, 4, and 5 months, a booster immunization at 18-24 months, and another booster at the age of 6.

Can whooping cough heal by itself?

Whooping cough is a respiratory infectious disease. If the infection is mild and the patient's immune system is normal, they can recover without medication. However, the specific clinical individual differences vary, and decisions should be based on the child's constitution, the quantity of the pathogen, and specific symptoms. If symptoms such as paroxysmal spasmodic coughing or a bark-like cough, which are typical of respiratory infections, appear, it generally will not heal on its own and requires anti-inflammatory medications to eliminate the pathogens and symptomatic treatment.

What should be paid attention to in the diet for whooping cough?

Whooping cough is an acute respiratory infectious disease caused by infection with Bordetella pertussis, mainly characterized by paroxysmal spasmodic cough, crowing inspiratory noise, commonly seen in children. In terms of diet, children with whooping cough should eat light and nutritious food. Do not eat spicy, greasy, or cold foods, as spicy foods can irritate the tracheal mucosa, and cold or greasy foods can damage the spleen and stomach, potentially exacerbating inflammatory changes.

What are the characteristics of the onset of whooping cough?

Pertussis is characterized by its distinctive cough, featuring episodes of spasmodic coughing that is intense and can lead to redness in the face and ears, a runny nose, nausea, vomiting, and headaches, among other complications. Some infants and toddlers may also exhibit a bark-like cough and an inspiratory "crowing" sound. Clinically, it is most commonly seen in children under five years of age. Diagnosis requires testing such as pathogen culture, complete blood count, and chest X-rays. Targeted antibacterial and anti-inflammatory treatments are then administered accordingly.
