Pertussis without a crowing sound indicates recovery. Pertussis, also known as whooping cough, is an acute respiratory infection caused by Bordetella pertussis, commonly seen in children. The progression of pertussis can be divided into three stages: The first stage is the catarrhal stage, also known as the pre-paroxysmal stage. At the early stage, the child shows symptoms similar to the common cold, followed by worsening cough. If the condition is not effectively controlled during this stage, It then progresses to the second stage, the paroxysmal stage. During the paroxysmal stage, the child exhibits characteristic episodic spasmodic coughing and crowing inhalation sounds. This period can last up to two months. Finally, it moves into the recovery stage. In the recovery stage, the frequency and severity of the episodic spasmodic cough and crowing inhalation sounds gradually alleviate. Thus, the absence of a crowing sound in whooping cough is an indication of approaching recovery.

The difference between pertussis and allergic cough

Pertussis (whooping cough) and allergic cough are different. Firstly, pertussis is an acute respiratory infectious disease caused by Bordetella pertussis. Its symptoms include paroxysmal and frequent coughing, sometimes accompanied by a deep, crowing, inspiratory whoop sound. If not treated promptly, the condition can last for several months, which is why it is called whooping cough. Due to its high contagiosity and epidemic history, if infants contract pertussis, their condition can worsen, making them prone to complications like severe pneumonia or heart failure. However, allergic cough is a non-infectious condition primarily caused by hypersensitivity of the airways, easily triggered by various external allergens, leading to irritating dry coughs, but not worsening to lower respiratory tract infections. In daily life, by avoiding environmental allergens and using treatments such as nebulization and oral antiallergic medications, management is possible.

Pertussis vaccine side effects

In clinical practice, the pertussis vaccine commonly used is mostly the DTP (Diphtheria, Tetanus, and Pertussis) vaccine, which primarily includes diphtheria, pertussis (whooping cough), and tetanus. This vaccine effectively prevents these three infectious diseases. Common adverse reactions and side effects from the vaccine injection include local muscle site reactions such as redness, swelling, and hard lumps; if there is a secondary bacterial infection, it may also lead to purulent discharge. Additionally, some patients may experience transient fever symptoms, generally not lasting more than twenty-four hours, followed by common gastrointestinal reactions.

Symptoms and Treatment of Whooping Cough in Children

The common symptoms of whooping cough are coughing, prolonged coughing, and spasmodic coughing, which ends with a crowing sound, and it mainly occurs during the night. The face may turn bright red during coughing, which is a typical symptom of whooping cough. For treatment, in the early stages of whooping cough, erythromycin is definitely used and can be effective. However, in pediatrics, if the whooping cough has lasted for a long time, the effectiveness of the treatment is relatively not as good. If the coughing period is long and medication is used in the middle to late stages, even with some treatment, it might still continue for two to three months. Although treatments like cough suppressants and expectorants can alleviate the symptoms, a cough usually still persists to some degree.

Is whooping cough an infectious disease?

Pertussis, also known as whooping cough, is a contagious disease that is a respiratory tract infection. It primarily spreads through airborne droplets and close daily contact. Clinically, there is a vaccine available for this condition, mainly the DTP (diphtheria, tetanus, and pertussis) vaccine. Following the vaccination schedule and developing antibodies can effectively prevent the disease. This disease has a lengthy course and can easily cause recurrent coughing episodes and persistent symptoms. It is important to correctly understand and be aware of the characteristics of its onset. If suspected, early examination and timely selection of medications for symptom control are essential, along with addressing the underlying cause.

Is nebulization useful for pertussis?

Nebulized inhalation for localized treatment of pertussis can be quite effective. It helps alleviate bronchial smooth muscle spasms and is used for spasmodic coughs, effectively easing cough symptoms as a symptomatic treatment measure. However, it is also necessary to target the infectious pathogens with oral or intravenous macrolide antibiotics for anti-inflammatory treatment. Drinking plenty of water, maintaining suitable indoor temperature and humidity, and having confidence in overcoming the disease are important. Although the course of the disease may be long, complete recovery is possible through proper treatment, so there is no need for excessive worry.
