These findings tell us that many people who eat at fast-food restaurants may not be making informed choices because they don't know how many calories they're consuming, Block said. None of the chains involved in the study included nutritional information on their menus, the researchers pointed out.
Diphtheria is caused by the c orynebacterium diphtheriae bacterium. Itâs most commonly spread through person-to-person contact or contact with items that have the bacteria on them.Coming into contact with items such as an infected personâs cup or used tissue can transfer the bacteria.he vaccine for diphtheria is given in a single shot (along with vaccines for pertussis and tetanus) that is called DTaP. The DTaP vaccine is administered in a series at 2, 4, and 6 months of age, and then again at around 1 and 4 years of age.
The case-fatality rate for diphtheria has changed very little during the last 50 years. The overall case-fatality rate for diphtheria is 5%â10%, with higher death rates (up to 20%) among persons younger than 5 and older than 40 years of age.Before there was treatment for diphtheria, the disease was fatal in up to half of cases. The incubation period of diphtheria is 2-5 days (range, 1-10 days).Diphtheria can involve almost any mucous membrane. For clinical purposes, it is convenient to classify diphtheria into a number of manifestations, depending on the site of disease:iphtheria once was a major cause of illness and death among children. The U.S. recorded 206,000 cases of diphtheria in 1921, resulting in 15,520 deaths. Starting in the 1920s, diphtheria rates dropped quickly in the U.S. and other countries that began widely vaccinating.
