Hint: The other two parts other than diphtheria included in the DPT can be a highly contagious bacterial disease characterized by cough and muscle spasms. Diphtheria is a serious bacterial infection caused by Corynebacterium diphtheria that affects the mucous membranes of the throat and nose.
The DPT vaccine (DPT) is a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus. The vaccine stimulates the production of antibodies to immunize the body against the causative agents of the three viruses.
The vaccine components include diphtheria and tetanus toxoids and either kill whole cells of the bacterium that causes pertussis or pertussis antigens.
The CDC (Centers for Disease Control and Prevention) recommended that children receive their first dose at two months, the second dose at four months, the third dose at six months, the fourth dose between fifteen-eighteen months, and the fifth dose between four-six years. Other doses of diphtheria-tetanus vaccine are suggested every ten years.
DPT is a vaccine against Corynebacterium diphtheria. It is the bacteria, which causes diphtheria. Diphtheria is typically spread between people by direct contact or through the air. It's going to even be spread by contaminated objects.
Signs and symptoms differ from mild to severe. They typically start two to 5 days after exposure. Symptoms often come on fairly gradually, beginning with pharyngitis and fever. In severe cases, a gray or white patch develops within the throat.
So, the correct answer is ‘Whooping cough and Tetanus’.
Note: Diphtheria is often prevented in those exposed to them and also treated with antibiotics. Protection is often verified by measuring the antitoxin level within the blood. The World Health Organization has suggested a vaccination for diphtheria since 1974.
