NATIONAL HEALTH PROGRAMMES

MALARIA
The National Anti-Malaria Programme is the world’s biggest health programme against a single communicable disease and continues to be the country’s most comprehensive and multi-faceted public health activity. Earlier deaths due to malaria were completely eliminated. Unfortunately, due to various factors, these achievements could not be maintained. Resurgence of malaria necessitated renewed vigourous anti-malaria activities and the programme was modified in the context of escalating malaria incidence. During the year 2008, 1.52 million cases and 0.76 million pf. cases with 935 deaths have been reported.

FILARIA
Lymphatic Filariasis is a serious debilitating and incapacitating. The infected person may develop swelling limbs and genitals which keep on increasing making the person incapacitated. This disease has been reported from over 250 districts in 20 states and UTs wherein over 590 million people live. The National Filaria control programme is being implemented since 1955. The national health policy has envisaged the goal of lymphatic filariasis elimination by the year 2015. In 2005, in 229 districts, 346.89 million persons were administered a dose of DEC against targeted population of 434.49 million, showing a coverage rate of 79.84%.

KALA-AZAR
Kala-azar is a parasitic disease caused by Leishmania donovani transmitted by sandflies phlebotomus orgentipes. Kala-azar is endemic in Bihar, Jharkhand, West Bengal and parts of Uttar Pradesh. National Health Policy, has envisaged the goal of Kala-azar elimination by the year 2010. The disease incidence has come down from 77,099 cases in 1992 to 44553 cases in 2007 and deaths from 1416 to 203 respectively. During the year 2008,33234 cases and 146 deaths have been reported. While till March, 2009, 2254 cases and 5 deaths were reported.

TUBERCLUOSIS
TB is serious public health problem in India. India accounts for nearly onefifth of Global TB burden. Every year there are approximately 19 lakh new cases in the country of which approximately 8 lakh are new smear positive and therefore highly infectious. To control TB, national TB control programme (NTCP) is in operation in the country since 1962. Two persons die from TB in India every three minutes more than 900 persons every day. In the year 2008, there were 3.8 million bacillary pulmonary cases, 3.9 million abacillary cases and 0.8 million extra-pulmonary cases.

LEPROSY The National Leprosy Control programme was launched by the Government of India in 1955. It was redesignated as the National Leprosy Eradication Programme (NLEP) in 1983. The second phase of National Leprosy elimination project was started from 1 April 2001 for a period of three years with the objective to achieve elimination of Leprosy as a public health problem by 2005, thereby reducing the case load to less than 1/10,000 population. In the year 1981, the country had a prevalance of 57.6 cases per 10,000 population which has come down to 0.72 per 10,000 population in March 2009.

BLINDNESS
The national programme for control of Blindness (NPCB) was launched in the year 1976 with the goal of reducing prevalence of blindness to 0.3 percent. As per survey in 2001-02, prevalence of blindness is estimated to be 1.1%. As per the survey conducted during 2006-07, the estimated prevalence of blindness has come down to 1%.

AIDS The AIDS programme implementation has been completely decentralized to States and Union Territories. Each state and Union territory has registered a state AIDs control society (SACS) responsible for implementating the programme at the State/UT level. In 2006, the country is estimated to have 3.1 million HIV positive persons, with an estimated adult HIV prevalence of 0.36%. Trends of HIV infection in 2006 indicate a mixed response in the country. While there is increase in some areas, in other areas it has shown decline. India continues to be in the category of concentrated epidemic. A total of 1,82,787 AIDS cases have been reported since 1986 till 31st March 2007.

MENTAL DISEASE
The national health programme was started in 1982 for providing community based mental health care using the existing public health infrastructure. The WHO report on Global Burden diseases has projected mental illness to be the fourth major cause of morbidity. Several mental disorders that include schizophrenia, bipolar disorder, organic psychosis and major depression affect nearly 20 per 1000 population.

CANCER
Cancer is an important public health problem in India with nearly 8-9 lakh new cases occurring every year in the country. It is estimated that there are 25 lakh cases of cancer in the country at any given point of time.According to a survey 40% of the cancer cases are due to comsumption of tobacco. With the objectives of prevention, early diagnosis and treatment, the National Cancer, Control programme (NCCP) was launched in 1975-76. The programme was revised in 1984-85 and subsequently in December 2005. There are 23 regional Cancer Centres recognized under the programme in different parts of countries to provide the specialized treatment and undertake research in the field of cancer.

INFORMATION TECHNOLOGY

Indian Information Technology and IT enabled serives (ITES-BOP) continue to chart remarkable growth. The Indian software and services export is estimated at Rs. 103200 crore (US $23.4 billion) in 2005-06, as compared to Rs. 80180 crore (US$ 17.7 billion) in 2004-05, an increase of 32 per cent in dollar terms.

The ITES – BPO

 sector has become the biggest employment generator amongst young college graduates with the number of jobs almost doubling each year. The no. of professinals employed in India by IT and ITES sectors is estimated at 1287000 as of March 2006.

National Plan on e-governance

The national Common Minimum programme adopted by the government accords high priority to improving the quality of basic governance and in that contest has proposed to promote e-governance on a massive scale in areas of concern to the common. A national egovernance plan has accordingly been drawn up covering 25 mission mode projects and of support components to be implemented at the Central, State and Local Government Levels.

MAJOR INITIATIVES IN INFORMATION TECHNOLOGY SECTOR

For realizing IT objectives, Data Connectivity and Services Delivering Access points need to be established all over the country, including the remotest areas. The Government is establishing State Wide Area Networks (SWANs) at a total outlay of Rs. 3,334 crore. These SWANs will extend data connectivity of 2 Mega bits per second upto the block level in State or Union Territory in the country. The block level nodes in turn, will have a provision to extend connectivity further to the village level using contemporary wireless technology. The government is also formulating a proposal to establish 100,000 common service centers that would extend the reach of electronic services, both government and private to the village level. Under the scheme, proposals from 26 states/UTs have already been sanctioned.

PC penetration- The department of Information technology has identified increase of PC penetration and internet utilization/coverage in the country; and growth of domestic software market as the thrust area for action during next 2-3 years. The department has set up six committees on low cost PC manufacturing; Education; e-Govenance, IT for Rural and Social sectors, Multilingual software Application and Contests; Internet penetration; and Telemedicine to prepare action plan in the respective sectors.

.IN Domain Name – In order to bring about a substantially increased proliferation of .IN Internet domain name, a new .IN Internet domain name policy was announced by the government in October 2004. It aims at adopting a liberal and market friendly approach to register large number of IN domain names. The policy has received wide acceptance country wide. The .IN inernet domain name registration has crossed 3,50,000 during December 2007.

Migration of IPV6 from Ipv4 : Internet protocol version 6 (Ipv6) is the next generation protocol of Internet to which migration is to take place from the currently used Internet Protocol version 4 (Ipv4). Ipv6 is essentially an upgrade to the data networking protocol that powers the internet. Keeping in view the global trends in Ipv6, the department of Information Technology took the initiative towards Ipv6 transition and National Roadmap for Ipv6 implementation.

Indian Language Technology – The benefits of information technology can reach the common man in India only when the digitised information is available in all Indian Languages. To enable wide proliferation of ICT in Indian languages, tools, products and resources should be freely available to the general public. The hindi software tools and fonts were released in June 2005.
