Infectious diseases remain as the major causes of human and animal morbidity and mortality leading to significant healthcare expenditure in India. The country has experienced the outbreaks and epidemics of many infectious diseases. However, enormous successes have been obtained against the control of major epidemic diseases, such as malaria, plague, leprosy and cholera, in the past. ⋯ Dynamic interplays of biological, socio-cultural and ecological factors, together with novel aspects of human-animal interphase, pose additional challenges with respect to the emergence of infectious diseases. The important challenges faced in the control and prevention of emerging and re-emerging infectious diseases range from understanding the impact of factors that are necessary for the emergence, to development of strengthened surveillance systems that can mitigate human suffering and death. In this article, the major emerging and re-emerging viral infections of public health importance have been reviewed that have already been included in the Integrated Disease Surveillance Programme.

To support recent political commitments to end tuberculosis (TB) in the World Health Organization South-East Asian Region (SEAR), there is a need to understand by what measures, and with what investment, these goals could be reached. These questions were addressed by using mathematical models of TB transmission by doing the analysis on a country-by-country basis in SEAR. ⋯ While the scale-up of currently available strategies may play an important role in averting TB cases and deaths in the Region, there will ultimately be a need for novel, mass preventive measures, to meet the end TB goals. Achieving these impacts will require a substantial escalation in funding for TB control in the Region.

Oxidative stress has been implicated in the pathophysiology of major depressive disorder (MDD), but biomarkers to assess oxidative stress in patients with MDD have yielded ambiguous results. Glutathionyl haemoglobin (GS-Hb) has been reported as a stable and potential biomarker for oxidative stress in various clinical conditions. The objective of the study was to evaluate GS-Hb as a potential biomarker of oxidative stress in patients with MDD through its quantification and to compare the levels of GS-Hb in age- and gender-matched healthy controls. ⋯ Compared to controls, GS-Hb level in patients with MDD was significantly elevated, suggestive of increased oxidative stress associated with MDD. However, six weeks of antidepressant treatment was not sufficient to modify the alterations in antioxidant/oxidant system. Further studies need to be done with a large sample of MDD patients with a longer duration of antidepressant treatment.
