Is Diphtheria Dangerous?

Diphtheria is an acute bacterial infection caused by Corynebacterium diphtheriae. This bacterium primarily attacks the mucous membranes of the upper respiratory tract, including the throat, nose, and larynx. In some cases, it can also affect the skin, eyes, and other organs.

The disease spreads mainly through respiratory droplets when an infected person coughs or sneezes. It can also be transmitted via contact with contaminated objects. If left untreated, diphtheria can progress to severe complications, such as airway obstruction, heart damage, nerve damage, and even death.

1. Causes of Diphtheria

Diphtheria is caused by the bacterium Corynebacterium diphtheriae, which produces a potent toxin. This toxin damages tissues and organs throughout the body.

Risk Factors:

• Lack of full vaccination against diphtheria.
• Living in crowded or unsanitary conditions.
• Close contact with infected individuals or asymptomatic carriers.
• Weakened immune system.

2. Symptoms of Diphtheria

Symptoms usually appear 2–5 days after infection. The most common signs include:

2.1. Respiratory Diphtheria

• Sore throat, mild fever, and chills: Early symptoms resemble the flu but worsen rapidly.
• Grayish-white pseudomembrane: A thick membrane forms in the throat, tonsils, or larynx, potentially leading to airway obstruction.
• Difficulty breathing and hoarseness: If the larynx is affected, breathing may become labored or produce a wheezing sound.
• Swollen lymph nodes and a “bull neck” appearance: The neck may swell significantly.
• Fatigue and weakness: Patients often experience loss of appetite and prolonged exhaustion.

2.2. Cutaneous Diphtheria

• Skin ulcers with a grayish covering, slow to heal.
• Possible secondary skin infections.

3. Is Diphtheria Dangerous?

Yes, diphtheria is highly dangerous if not treated promptly. Severe complications include:

• Airway obstruction: The pseudomembrane can block breathing, leading to fatal respiratory failure.
• Myocarditis (heart inflammation): The diphtheria toxin can damage the heart, causing irregular heartbeats and heart failure.
• Nerve damage: The toxin may cause paralysis of cranial nerves, affecting swallowing, speech, and breathing.
• Acute kidney failure: In severe cases, toxin buildup can lead to kidney damage.
• Death: The fatality rate ranges from 5–10%, with higher risks in young children and the elderly.

4. How to Prevent Diphtheria

4.1. Vaccination

• Vaccination is the most effective prevention method.
• The diphtheria vaccine is included in combination vaccines such as DTP (Diphtheria, Tetanus, and Pertussis).
• The immunization schedule includes three primary doses for infants and booster shots as recommended by health authorities.

4.2. Personal Hygiene

• Wash hands regularly with soap.
• Avoid contact with infected individuals or those showing symptoms.
• Wear a mask in crowded places.

4.3. Improve Living Conditions

• Maintain a clean home environment.
• Avoid overcrowded or polluted living spaces.

5. How to Treat Diphtheria

Suspected diphtheria patients must seek immediate medical care. Treatment options include:

• Antibiotics (Erythromycin, Penicillin): Kill the diphtheria bacteria.
• Diphtheria Antitoxin (DAT): Neutralizes the diphtheria toxin and reduces complications.
• Respiratory support: Oxygen therapy or tracheostomy may be necessary in severe cases.
• Patient isolation: Prevents the spread of infection to others.

6. Conclusion

Diphtheria is a life-threatening infectious disease with severe complications, but it can be effectively prevented through vaccination and good hygiene practices. Early detection and prompt treatment significantly reduce the risk of death and prevent the spread of the disease in the community.
