What is the mortality rate for diphtheria, and how does it vary by age?

Question

Accepted Answer

Diphtheria Mortality Rates Vary Significantly by Age

One in ten individuals infected with diphtheria will die from the disease, with the mortality rate increasing substantially for young children. For those under the age of five, the fatality rate rises to one in five. This underscores the severe and disproportionate impact of diphtheria on the youngest populations.
Diphtheria Causes Widespread Systemic Damage

Beyond the characteristic throat membrane that can obstruct airways and lead to suffocation, diphtheria infections produce toxins that can severely damage the heart and nervous system. This can result in abnormal heart rhythms, heart failure, paralysis, and ultimately, death. The disease spreads through coughing and sneezing and remains infectious for up to two weeks.
Diphtheria Cases and Fatalities in Malaysia

In 2017, Malaysia recorded 32 cases of diphtheria, resulting in seven reported deaths. The severity of the disease was further highlighted by the deaths of a three-year-old in June and a 14-month-old in October of the following year, both attributed to diphtheria.
Diphtheria's Preventability Through Vaccination

Diphtheria is a preventable infection, with vaccination being the primary means of protection. Despite its preventability, the disease has seen a resurgence, a trend that contradicts efforts to eliminate such infections. The high mortality rates, particularly among young children, emphasize the critical need for widespread immunisation.
