A37.90 Whooping cough, unspecified species without pneumonia

Name of the Condition

• Whooping Cough, Unspecified Species Without Pneumonia (Pertussis)

Summary

Whooping cough, medically known as pertussis, is a contagious respiratory disease characterized by severe coughing fits. This condition can affect people of all ages, although it's particularly serious for infants and young children.

Causes

Whooping cough is primarily caused by the bacterium Bordetella pertussis. It spreads easily from person to person through respiratory droplets when an infected individual coughs or sneezes.

Risk Factors

• Close contact with an infected person.
• Not being vaccinated or outdated vaccination.
• Infants and children under the age of 1.
• Living or working in crowded conditions.

Symptoms

• Severe coughing fits followed by a "whooping" sound when breathing in.
• Vomiting after coughing.
• Fatigue and exhaustion due to intense coughing bouts.
• Mild fever and runny nose in the early stages.

Diagnosis

• Physical examination and review of symptoms.
• Nasopharyngeal swab to identify the presence of Bordetella pertussis.
• Blood tests to support diagnosis in some cases.

Treatment Options

• Antibiotics to eliminate the bacterial infection and help prevent its spread.
• Supportive care such as rest, hydration, and managing symptoms.
• Hospitalization might be necessary for severe cases, especially in infants.

Prognosis and Follow-Up

With prompt treatment, the prognosis for whooping cough is generally good, but the recovery period can be prolonged. Regular follow-up is crucial to monitor recovery and prevent complications.

Complications

• Severe dehydration and weight loss from vomiting.
• Secondary bacterial infections such as pneumonia.
• Prolonged recuperation period, especially in young children and infants.

Lifestyle & Prevention

• Ensure up-to-date vaccinations (DTaP for children, Tdap boosters for adults).
• Practice good hygiene, such as regular handwashing and covering the mouth when coughing.
• Avoid close contact with infected individuals.

When to Seek Professional Help

• Persistent or severe coughing fits.
• Difficulty breathing or whooping sound when inhaling.
• Signs of dehydration in infants, such as dry mouth and lack of tears.
