Is Diphtheria Highly Contagious?

Diphtheria is a dangerous infectious disease caused by the bacterium Corynebacterium diphtheriae. This bacterium produces toxins that attack the mucous membranes of the throat, nose, and skin, potentially causing severe damage to the heart, kidneys, and nervous system. If not treated promptly, diphtheria can be fatal.

Before the introduction of vaccines, diphtheria was one of the leading causes of death in children. However, in recent years, the disease has resurged in some areas due to low vaccination rates.

1. Is Diphtheria Highly Contagious?

Yes, diphtheria is highly contagious, especially in crowded environments such as schools, daycare centers, and densely populated areas. The main transmission routes include:

• Respiratory droplets: The bacteria spread through the air when an infected person coughs, sneezes, or talks.
• Direct contact: Touching secretions from an infected person, such as nasal discharge, saliva, or infected skin lesions, can spread the disease.
• Contaminated personal items: Sharing objects like drinking glasses, toothbrushes, or towels can also facilitate bacterial transmission.

Those at higher risk include unvaccinated children, individuals living in poor sanitary conditions, and people who have close contact with infected individuals without proper protection.

2. Symptoms of Diphtheria

Diphtheria has an incubation period of 2–5 days. Early symptoms often resemble the common flu, including:

• Mild fever, fatigue, loss of appetite
• Sore throat, difficulty swallowing
• Swollen lymph nodes in the neck
• A thick, grayish-white membrane forming in the throat, tonsils, or larynx

In severe cases, bacterial toxins can damage the heart, kidneys, and nervous system, leading to myocarditis, paralysis, or even death.

3. How to Prevent Diphtheria

The best way to prevent diphtheria is through full vaccination according to immunization schedules. The diphtheria vaccine is usually combined with the pertussis and tetanus vaccines (DTP). Children should receive all required doses under the national immunization program.

Additional preventive measures include:

• Maintaining personal hygiene and washing hands frequently with soap
• Avoiding close contact with infected individuals or those showing symptoms
• Wearing masks in public, especially in outbreak areas
• Keeping the living environment clean and well-ventilated

4. Treatment for Diphtheria

Early treatment is crucial to prevent severe complications. If diphtheria is suspected, immediate medical attention is necessary. Treatment options include:

• Diphtheria antitoxin to neutralize bacterial toxins
• Antibiotics such as erythromycin or penicillin to eliminate the bacteria
• Supportive care, including oxygen therapy or IV fluids if needed

Patients must be isolated to prevent spreading the infection. Close contacts of the infected person should also be tested and given preventive treatment if necessary.

5. Conclusion

Diphtheria is a dangerous, highly contagious disease that can be fatal if not treated promptly. However, it is preventable with proper vaccination. Everyone should take responsibility for their health by ensuring full immunization, maintaining good hygiene, and avoiding contact with infected individuals. If diphtheria symptoms appear, seek medical attention immediately for timely diagnosis and treatment.
