Measures to control such diseases:
- Integrated Disease Surveillance Project (IDSP): It is an initiative by the government of India to strengthen/maintain decentralized laboratory based IT enabled disease surveillance system for epidemic prone diseases to monitor disease trends and to detect and respond to outbreaks in early rising phase through trained Rapid Response Team (RRTs).
- Rashtriya Bal Swasthya Karyakram (RBSK): It is a program under the Ministry of Health & Family Welfare to improve the quality of life for children upto the age of 18 years. It primarily screens the children for 4 D’s : Defects at birth, Diseases, Deficiencies and Development delays.
- National Vector Borne Disease Control Programme: This program is launched for the prevention and control of major Vector Borne Diseases like filaria, malaria, kala azar, dengue, Japenese Encephilitis.
