Mission Indradhanush
The percentage of children, who are fully immunized (FIC), was found to be only 65% in 2013-14. This was despite the Universal Immunization Program (UIP) running since 1985 and Expanded Program on immunization (EPI) since 1978.
Mission Indradhanush was launched in December 2014 to:

Rat control measures:
1. Sanitation
2. Trapping: Bait is used. Causes temporary reduction in numbers.
Captured rats must be killed as they become “trap-wise” and avoid traps later
1. Mechanical: infectious agent is mechanically transported through soiling of vector’s feet or proboscis or by passage through its gastrointestinal tract. for example spread of e coli by housefly
2. Biological:
a. Propogative: infectious agent merely multiplies inside the vector e.g. plague in rat flea
b. Cyclo-propogative: agent changes in number and also in form e.g. malaria parasites in mosquito
c. Cyclo-developmental : the disease agent undergoes only development but no multiplication e.g. microfilaria in mosquito
