Diphtheria causes inflammation of the upper respiratory tract, including the nose and throat. Symptoms may include sore throat, breathing problems, bloody or watery drainage from the nose, hoarseness, a bark-like cough and painful swallowing. Swelling of the throat and neck is characterised by a ‘bull neck’. Some cases will experience infection of the skin, resulting in skin lesions. However, some cases may not experience any symptoms.

People suspected of having diphtheria will be given an antitoxin injection to the muscle or into the vein. Infection is then treated with antibiotics, such as erythromycin or benzathine penicillin. Additional treatment may include intravenous fluids, oxygen, bed rest, heart monitoring, use of a breathing tube, and correction of any blocked airways.

The effects of diphtheria can range from mild to severe.

• For those infected, there is the potential for the diphtheria bacteria to release harmful toxins which can spread through the blood stream and affect major organs
• Diphtheria toxin can cause significant damage to the heart, nerves, and kidneys
• Diphtheria can be fatal. 5-10% of those infected die, even with treatment
