A diphtheria epidemic in New England's colonies between 1735 and 1740
*cough cough, cough*
Diphtheria can spread by airborne droplets, contaminated personal and household items.
100,000 to 200,000 people got sick and 13,000 to 15,000 died per year. Among people younger than 5 and older than 40 years of age.
In the spring of 1913, Behring developed a vaccine against diphtheria. Today, more than 80% or children in the United States are vaccinated. Those who contract the disease are treated with antibiotics.
Diphtheria particularly occur in tropical countries
Diphtheria launches most of it's attacks in winter or/and spring, but it can happen anytime, especially in warmer climates.
