Diphtheria Causes, Signs, and Remedies
Diphtheria, a highly contagious bacterial infection, is caused by Corynebacterium diphtheriae. This disease is preventable through vaccination and prompt treatment, but it can still pose a significant threat if left untreated.
The infection primarily affects the respiratory system or the integumentary system (skin). Symptoms include a thick, gray coating in the nose and throat, sore throat, swollen glands, weakness, and mild fever. If the pseudomembrane extends to the larynx, hoarseness and a barking cough become more likely, as does the danger of complete obstruction of the airway.
Early treatment with antitoxin is crucial, as it only works on toxins that have not yet bound with cells and tissue in the body. Treatment for diphtheria has two components: antitoxin and antibiotics. Antitoxin neutralizes circulating toxin, reducing the risk of systemic complications, while antibiotics eradicate the bacteria and stop toxin production.
Common complications of diphtheria primarily arise due to the exotoxin produced by Corynebacterium diphtheriae, which spreads through the bloodstream and damages various organs. Complications can include cardiac complications, neurological complications, respiratory complications, and renal complications.
Cardiac complications, such as toxic myocarditis, are frequent and can cause arrhythmias, heart block, heart failure, and cardiogenic shock. Neurological complications can lead to paralysis, affecting swallowing and breathing muscles, risking respiratory failure. Respiratory complications may cause airway obstruction, leading to respiratory distress and failure. Renal complications can result in acute renal failure.
Prevention is key, and the diphtheria vaccine is the primary preventive measure. Modern vaccination schedules include diphtheria toxoid as a childhood immunization, known as diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP). Booster doses are recommended if the last vaccine was given over 5 years ago.
In the U.S. and other parts of the world, routine immunization has significantly reduced the risk of diphtheria exposure. However, it is essential to maintain vigilance, especially for those ages 11-13 years who should receive the Tdap shot, and adults who should receive the Td or Tdap every 10 years.
If a person contracts diphtheria, they can spread the infection through direct physical contact with respiratory droplets, secretions from the nose and throat, or infected skin lesions. It is crucial that a person finishes the full course of antibiotics to ensure they are no longer contagious after 24 hours.
In conclusion, early vaccination, prompt diagnosis, antitoxin administration, antibiotics, and supportive care are key to preventing and managing diphtheria complications effectively. If you suspect diphtheria, seek medical attention immediately.
