i) DPT (Diphtheria, Pertussis, Tetanus)
(ii) Polio
Diphtheria is a highly contagious disease, usually transmitted via droplet particles that are coughed or sneezed into the air. It can cause a thick covering in the back of the throat that can lead to breathing problems or heart failure.
Tetanus is another very serious infection that is caused by a bacterial toxin. The bacteria enters the body through an open wound, multiplies, and produces a toxin that can affect nerves controlling muscle activity. A common symptom of tetanus infection is stiffness of the jaw muscles.
Pertussis, or whooping cough, is an upper respiratory illness caused by a bacterium. The organism is highly contagious, spreads easily and can cause serious illness, especially in infants.
The primary signs of polio include muscle weakness, pain, and fatigue; ultimately, the illness can lead to paralysis and even death.
