Whooping cough: characteristics, causes of occurrence, and treatment methods

Definition and symptoms of Whooping Cough

Pertussis (whooping cough) is an acute infectious disease of the upper respiratory tract caused by the bacterium Bordetella pertussis. It is characterized by periodic attacks of severe coughing, often with a distinctive whistling sound upon inhalation, which is why it is also called “the whooping cough” or “the 100-day cough.” In pertussis, vomiting after coughing, sleep disturbances, urinary incontinence, and distress can also occur. Laboratory confirmation methods such as PCR or throat culture for streptococci are often required to verify the diagnosis of whooping cough.

The characteristic symptoms of pertussis may vary depending on the stage of the disease; however, they most often begin with a runny nose, mild fever, and a cough resembling an ordinary acute respiratory viral infection. The cough then becomes increasingly intense and paroxysmal, possibly accompanied by episodes of sneezing and pallor of the skin. The most critical stage of pertussis is the climax, when the cough becomes most intense and problematic for the patient.

Etiology of Whooping Cough

Whooping cough, or pertussis, is caused by the bacterium Bordetella pertussis. This is a Gram-negative coccobacillus capable of infecting the human respiratory tract. The infection is transmitted through the airborne route when a person infected with whooping cough coughs or sneezes.

The main causes of whooping cough are related to the spread of the bacterium in public places, low vaccination compliance, and the ability of Bordetella pertussis to cause acute respiratory infection among unvaccinated individuals. Although whooping cough is often associated with childhood, it can also affect adults due to loss of immunity caused by lack of regular vaccination or insufficient protection from previous vaccinations.

  • Bordetella pertussis bacteria: the main pathogen causing whooping cough, infects the human respiratory tract.
  • Bacterial transmission: the infection is transmitted through airborne droplets when an infected person coughs or sneezes.
  • Spread in public places: poor hygiene, close contacts, and dense crowds contribute to the transmission of the bacteria.
  • Low vaccination rates: insufficient vaccination of the population leads to the possibility of epidemics and widespread transmission of whooping cough.
  • Ability to cause acute illness: Bordetella pertussis can lead to serious respiratory infection in unvaccinated individuals, adding complexity to the fight against whooping cough.

The clinical picture of whooping cough

The clinical picture of Whooping Cough is characterized by three main stages: catarrhal, paroxysmal, and convalescent. In the early stages of the disease, symptoms typical for the upper respiratory tract appear, such as a runny nose, itchy throat, and slight fever.

In the paroxysmal stage, characteristic paroxysmal coughing fits are observed, accompanied by coughing, cyanosis, and sometimes vomiting. These episodes can be so intense that they disrupt the normal functioning of the respiratory pathways, which poses a risk for the development of complications.

  • Catarrhal stage: At this stage of whooping cough, symptoms are similar to a common cold and mild cough. The patient may experience slight malaise, throat itching, and a slight increase in temperature.
  • Paroxysmal stage: Characterized by paroxysmal coughing fits that become more intense and prolonged. Coughing may also be accompanied by cyanosis and vomiting due to the intense coughing.
  • Dyspnea: During coughing fits, patients may experience dyspnea and difficulty breathing due to frequent and intense spasms of the respiratory muscles.
  • Hoarse voice: The whooping cough may be so severe that it leads to a change in the patient’s voice, which becomes hoarse or uneven.
  • Cyanosis: Due to oxygen deprivation caused by severe coughing fits, patients may start to develop cyanotic areas on the skin of the face and lips.

Experts’ opinions on Whooping Cough treatment

Medical experts recommend a comprehensive approach to the treatment of Whooping Cough, which includes the use of antibiotics, symptomatic therapy, as well as hospitalization in cases of complications and severe forms of the disease. One of the key measures is to prevent the spread of infection through vaccination, as preventive shots help reduce the risk of illness and its severity.

Experts emphasize the importance of early diagnosis and proper care for patients with Whooping Cough, particularly vulnerable groups such as children and individuals with weakened immune systems. Under strict medical supervision and with appropriate treatment, the recovery process can be successful and help prevent complications and further spread of the disease.

Methods for Diagnosing Whooping Cough

Diagnosis of Whooping Cough usually includes taking the patient’s medical history, physical examination, laboratory tests, and molecular biological methods such as PCR to detect Bordetella pertussis in nasopharyngeal swabs. The clinical picture of the disease has historically been an important factor in diagnosing Whooping Cough, especially during epidemics or in contact cases.

In cases suspected of Whooping Cough, serological testing may also be used to detect antibodies against Bordetella pertussis. Some cases may require radiological studies to identify complications such as pneumonia. Overall, a comprehensive approach to the diagnosis of Whooping Cough includes various methods to confirm the presence of the infection and initiate timely treatment.

  • Collection of medical history and physical examination: Important indicators include contact with possible sources of infection and characteristic symptoms of the disease.
  • Laboratory tests: Include a complete blood count, bacteriological studies, and molecular biological methods for detecting Bordetella pertussis.
  • Serological testing: Allows for the detection of antibodies to the causative agent of the disease.
  • Radiological studies: May be used to identify complications such as pneumonia.
  • Clinical diagnostic methods: Include visual examination of mucous membranes, auscultation of the lungs, and other methods that allow for the identification of characteristic signs of Pertussis.

Whooping cough treatment

Treatment of Whooping Cough generally involves the use of antibiotics that alleviate cough and symptoms of the disease. Early initiation of antibiotic therapy can reduce the period of contagiousness and complications of the illness. General recommendations for treatment include maintaining hydration and effective breathing, which is especially important for patients with severe coughing fits.

Preventive vaccination is considered one of the key methods for preventing Whooping Cough in children and adults. Additional medical therapy and hospitalization may be required for treating complications such as pneumonia. Patients diagnosed with Whooping Cough should receive a level of care and treatment that corresponds to their clinical condition and needs.

  • Use of antibiotics: Antibiotics are generally used to treat Whooping cough, especially in children and individuals at high risk of complications.
  • Symptomatic treatment: Treatment is aimed at relieving symptoms such as cough, shortness of breath, and other manifestations of the disease.
  • Maintaining hydration: It is important to ensure adequate fluid intake and humidity in the air to facilitate sputum production and reduce throat irritation.
  • Preventive vaccination: Vaccination is a key measure for preventing the disease, especially in children and individuals who have been in contact with infected persons.
  • Emotional support and care: Patients with Whooping cough require support from those around them, emotional support, and appropriate care for a speedy recovery.

Prevention of Whooping Cough

The prevention of Whooping Cough includes the widespread use of vaccination, which is recommended for all children and adults. As of today, the primary method of preventing Whooping Cough is the vaccination with acellular whooping cough vaccines included in combination vaccination schedules. Early and complete vaccination coverage of the population is considered an effective way to prevent the disease and its complications.

In addition to vaccination, the prevention of Whooping Cough also includes limiting contacts with infected individuals and maintaining an optimal level of hygiene, which can reduce the risk of infection. Effective preventive measures play an important role in mitigating the epidemiological situation and reducing the prevalence of the disease in society.

  • Vaccination: The main method of pertussis prevention is the use of acellular pertussis vaccine, included in vaccination schedules for children and adults.
  • Limiting contacts: Prescribed isolation and maintaining distance from infected individuals can help prevent the spread of the infection.
  • Maintaining hygiene: Regular handwashing, especially after visiting public places, reduces the risk of infection and the spread of pertussis.
  • Healthy lifestyle: A healthy lifestyle, including balanced nutrition, physical activity, and adequate rest, strengthens the immune system and promotes resistance to infections.
  • Early diagnosis and treatment: Timely detection and treatment of pertussis not only help patients overcome the disease but also prevent its spread in the community.

Unusual Aspects of Whooping Cough

Whooping cough, although well studied with known causes and mechanisms, can still present some unusual aspects. For example, the disease can be more severe in infants, children, and unvaccinated adults. In older children and adults, the virus may cause mild symptoms, which is why whooping cough is often undiagnosed or underestimated.

Another interesting fact about whooping cough is its potential for asymptomatic infection, where a person is infected but does not exhibit symptoms of the disease. This can lead to an underestimation of the spread of the infection in society and complicate disease control. Such unusual aspects require additional attention and research for more effective control and treatment of whooping cough.
