Despite the remarkable strides in medical science over the last century, infectious diseases continue to pose a significant risk to global health.

While some diseases like HIV and tuberculosis are commonly recognized, others have become obscure in the collective consciousness due to successful control measures. Among these is Diphtheria – a bacterial infection that remains a vital public health concern.

What is Diphtheria?

Diphtheria is an infectious disease caused by the bacterium Corynebacterium diphtheriae. It primarily affects the mucous membranes of the throat and nose, although it can also affect the skin. The bacteria produce a toxin that can harm tissues in the immediate area of infection and, if it enters the bloodstream, can cause severe damage to the heart, kidneys, and nervous system.

Symptoms of Diphtheria

Early symptoms of diphtheria resemble those of a common cold, which include a sore throat, fever, and swollen glands in the neck. The distinguishing symptom, however, is a thick, gray covering in the throat or nose, which can make breathing and swallowing difficult.

If left untreated, the toxin can spread through the bloodstream leading to potential complications like heart inflammation, kidney problems, and nerve damage, which can cause paralysis. These complications can be severe and sometimes fatal.

How is Diphtheria Spread?

Diphtheria is highly contagious. It spreads through respiratory droplets when an infected person coughs or sneezes, or through close contact. It can also be spread by contaminated objects or foods. Although rare, diphtheria can also spread through skin sores.

Diphtheria Vaccination: The Primary Preventive Measure

Vaccination is the most effective way to prevent diphtheria. The diphtheria vaccine, often combined with vaccines for tetanus and pertussis (whooping cough), is included in the routine childhood immunization schedule. It's usually given in a series of five doses starting at two months of age, with a booster shot recommended every 10 years.

Despite the widespread availability of the vaccine, there are still pockets of the world where diphtheria is endemic, mainly due to low immunization coverage.

Treatment of Diphtheria

Diphtheria is a treatable condition. The first step is to administer diphtheria antitoxin to neutralize the toxins produced by the bacteria. This is followed by antibiotics, such as penicillin and erythromycin, to clear the bacteria from the body.

The Importance of Awareness

Diphtheria may not be a common headline-grabbing disease today, thanks to the effectiveness of vaccines. However, the risk persists, particularly in areas with low vaccination rates. It is vital to maintain high immunization coverage to prevent resurgence.

Therefore, it is crucial to raise public awareness about diphtheria and the importance of vaccination. With knowledge and preventive measures, we can continue to keep this formidable disease at bay and safeguard public health.

In conclusion, diphtheria is a potent reminder that even diseases seemingly relegated to the pages of history can pose a significant threat if complacency sets in. The best defense against this disease is knowledge, awareness, and above all, timely and complete vaccination.
