A host of health initiatives aimed at the control of communicable and non-communicable diseases in the State will be launched on Wednesday as part of the World Health Day observance.

The theme of this year's World Health Day — ‘‘1,000 lives, 1,000 cities'' — will focus on urbanisation and health. The Health Department has planned the launch of two initiatives on Wednesday, aimed at tackling both infectious as well as non-communicable diseases, the major fallouts of urbanisation.

The ‘Four Plus campaign' has been planned as a year-long intensive infectious diseases control programme which will focus on four core strategies to tackle four major diseases — dengue, chikungunya, malaria and leptospirosis. The other programme is a community-oriented health initiative to screen people early for lifestyle diseases and to ensure that they get continuous medical care.

The four main components of the Four Plus programme include early monitoring of disease patterns, launch of appropriate preventive and control measures, behavioural change communication to tackle public's approach to disease prevention and review and supervision of activities at all levels. Various other departments, including the Local Self-Government, Education, Animal Husbandry, Water Resources, etc., will also cooperative with this initiative. Vector control activities with increased public participation, intersectoral coordination , monitoring of vector density through regular house visits by Health workers and Kudumbasree/ASHA volunteers, regular reporting of the fever statistics from primary health centres and other institutions in the periphery, including private hospitals have been envisaged under the programme.

The Four Plus campa ign focussing on Medical College Hospital will be launched on Wednesday.
