There is an increased connectedness among humans, animals, and the environment and the current pandemic has taught the interlinking of the health of humans, animals and the planet. This inter-connectedness and factors like population growth, migration, urbanization, and climate change contribute significantly to the enhanced probability of emergence of previously unknown wildlife source pathogens at any place, any time, and without warning. Lurking in the background is the massive potential for the deliberate use of biological agents as weapons by State or non-State entities. ⋯ Every country including India is at risk of biothreat. The concept of one health is thus essential for responding to emerging infectious diseases or biothreats. Comprehensive surveillance for early detection, reporting and early concerted action is needed for prevention and blunting the effect of biothreats, which require close coordination and collaboration among various stakeholders within each country as well as globally.

Zika virus (ZIKV), member of the family Flaviviridae belonging to genus Flavivirus, is an arthropod-borne virus. The ZIKV is known to cause severe congenital birth defects in neonates. Due to a large number of worldwide outbreaks and associated neurological complications with ZIKV, a public health emergency was declared by the World Health Organization on February 1, 2016. ⋯ The virus modulates cell machinery at several levels to replicate itself and inhibits toll like receptors-3 signalling, deregulates microRNA circuitry and induces a chronic inflammatory response in affected cells. Several significant advances have been made to understand the mechanisms of neuropathogenesis, its prevention and treatment. The current review provides an update on cellular and molecular mechanisms of ZIKV-induced alterations in the function of various brain cells.

Japanese encephalitis/acute encephalitis syndrome (JE/AES) is one of the major zoonotic arbodiseases that has a significant effect on human and animal health. Though many studies have been published on the epidemiology and transmission mechanisms of JE/AES, but there is little evidence on health system preparedness, including community-based engagement. This study was undertaken to explore a multi-stakeholder perspective on health system preparedness for the prevention of JE/AES in a tribal district of Odisha, India. ⋯ Community participation and coordination between different stakeholders have a significant impact on the successful implementation of the programme. It was suggested that there was a need for a sustainability approach to active participation, orientation and capacity building training among CHWs and community volunteers to successfully implement the programme.

Issues such as emerging and re-emerging infectious diseases, antimicrobial resistance, food security, biosafety and biosecurity are associated with changes in land use, population growth, urbanization, global travel and trade and climate change. As a result, a trans-disciplinary approach among human, animal and environmental health disciplines gained support. The Indian Council of Medical Research (ICMR) and Indian Council of Agricultural Research (ICAR) decided to establish a National Institute of One Health at Nagpur, Maharashtra, India. In this context, two collaborative research projects, funded by the ICAR and ICMR were initiated to conduct the epidemiological surveillance of selected zoonotic diseases in Central India. ⋯ The data indicated the occurrence of important zoonotic diseases adversely affecting the livestock health and human wellbeing. The scientific collaboration between veterinary and medical faculties has set an example for effective implementation of One Health (OH) programme for the establishment of National Institute of OH.
