Background & Objectives: A remarkable progress is being made in the South-East Asia region in reducing the burden of malaria. While all countries are committed to malaria elimination, continued transmission at and across international borders poses a threat to achieving this goal.
Methods: We investigated an outbreak of malaria in the India-Bhutan border area in a district of Assam state, India.
Objectives: To estimate the impact of a smallpox attack in Mumbai, India, examine the impact of case isolation and ring vaccination for epidemic containment and test the health system capacity under different scenarios with available interventions.
Setting: The research is based on Mumbai, India population.
Interventions: We tested 50%, 70%, 90% of case isolation and contacts traced and vaccinated (ring vaccination) in the susceptible, exposed, infected, recovered model and varied the start of intervention between 20, 30 and 40 days after the initial attack.
Background: Hepatitis-E Virus (HEV) infection is endemic in Punjab, India. On 4th April 2013, public officials of Labour Colony, Amritsar reported > 20 jaundice cases occurring within several days.
Methods: We performed a case-control study to identify the cause and prevent additional cases of jaundice cases in Amritsar, Punjab, India in 2013.

To strengthen epidemiological capacity in the country, the Government of India in 2012 initiated a unique, competency-based training in epidemiology. Modeled along the United States Epidemic Intelligence Service (EIS), this 2-year mentor-driven and practical-oriented program, based on "learning by doing," is being implemented by the National Centre for Disease Control in Delhi, in close collaboration with the US Centers for Disease Control and Prevention, Atlanta. In its 4 year now, many lessons learned so far are being used to expand the program, without compromising on the technical quality.

Objectives: To describe cases and deaths of 2013 pH1N1 positives, to evaluate the high case fatality ratio and risk factors for pH1N1-associated mortality among the hospitalized cases in Punjab for 2013.
Methods: A case-control study was conducted and compared those who died from confirmed pH1N1 with those who survived in the hospital between January 1, 2013, and April 30, 2013.
The burden of viral hepatitis in India is not well characterized. In 2009, the national Integrated Disease Surveillance Programme (IDSP) began conducting surveillance across all Indian states for epidemic-prone diseases, including foodborne and waterborne forms of viral hepatitis (e.g.

- * By 2004, this initiative successfully achieved yaws-free status across all 51 endemic districts in 10 Indian states.
- * Ongoing surveillance and serological surveys among young children confirmed the absence of community transmission, showing that with strong political and community support, yaws can be eradicated in other endemic regions as well.
