Pharyngeal diphtheria Save

Pharyngeal diphtheria, also known as respiratory diphtheria, is a highly contagious bacterial infection caused by Corynebacterium diphtheriae. This disease is characterized by the formation of a thick, grayish-white membrane that covers the back of the throat and tonsils. If left untreated, pharyngeal diphtheria can lead to severe complications such as airway obstruction, heart failure, and paralysis.

Transmission of pharyngeal diphtheria occurs through respiratory droplets or direct contact with infected fluids or materials. The incubation period for this disease is typically 2-5 days, during which time the infected individual may not exhibit any symptoms. Once symptoms begin to appear, they often include sore throat, fever, chills, malaise, and difficulty swallowing.

The hallmark feature of pharyngeal diphtheria is the formation of a pseudomembrane, which is a thick, grayish-white membrane that adheres to the back of the throat and tonsils. This membrane is composed of dead tissue, bacteria, and white blood cells, and can cause difficulty breathing and swallowing. In severe cases, the membrane may spread to the larynx and cause airway obstruction.

Diagnosis of pharyngeal diphtheria is typically made through a combination of clinical presentation, laboratory testing, and imaging studies. Laboratory tests such as throat cultures, polymerase chain reaction (PCR), and serology can confirm the presence of C. diphtheriae and its toxin. Imaging studies such as X-rays and CT scans may be used to evaluate for airway obstruction or other complications.

Prevention of pharyngeal diphtheria is primarily through vaccination with the diphtheria-tetanus-pertussis (DTP) vaccine. This vaccine is typically given to children in a series of doses during infancy and childhood, and booster doses may be given in adulthood. In addition, good hygiene practices such as frequent hand washing and avoiding close contact with infected individuals can also help prevent transmission.

In conclusion, pharyngeal diphtheria is a highly contagious bacterial infection that can cause significant morbidity and mortality if left untreated. Prompt diagnosis, treatment with antibiotics and antitoxin, and supportive care are essential for a good outcome. Vaccination and good hygiene practices are key in preventing the transmission of this disease.
