Over time, the focus has shifted from raising awareness to behavior change, from a national response to a more decentralized response and to the increasing involvement of NGOs and networks of PLHIV.
- The first phase focused on awareness generation, setting up surveillance systems for monitoring the HIV epidemic, measures to ensure access to safe blood and preventive services for high-risk group populations.
- The policy and strategic shift were reflected in the two key objectivesof NACP II:
- to reduce the spread of HIV infection in India,
- and to increase India’s capacity to respond to HIV/AIDS on a long-term basis.
- In response to the evolving epidemic, the third phase of the national program (NACPIII) was launched in July 2007 with the goal of Halting and Reversing the Epidemicby the end of the project period.

Greater Nocobar Island
Why in news?
Researchers have found litter from Malaysia, Indonesia, and Thailand on the island, which hosts a biosphere reserve.
- The pristine beaches of the Great Nicobar Island, India’s southernmost territory, are under threat from plastic. A survey of five beaches in the islands recorded the presence of plastic bottles.
- Major portion of the litter (40.5%) was of Malaysian origin. It was followed by Indonesia (23.9%) and Thailand (16.3%). Other countries contributed a minor portion.
- About 10 countries including India contributed to the plastic litter on the island. They were Malaysia, Indonesia, Thailand, Singapore, Philippines, Vietnam, India, Myanmar, China, and Japan.
- Plastic pollution has emerged as one of critical threats to ocean ecosystem.
- Plastic represents 83 % of the marine litter found.
- The remaining 17% is mainly textiles, paper ,metal & wood
- The overwhelming contribution from Indonesia and Thailand was likely due to its proximity to the island; the plastic is likely to have made its way to the island because of water currents via the Malacca Strait, which is a major shipping route.
- The huge quantities of marine debrisobserved on this island might be due to improper handling of the solid waste from fishing/mariculture activity and ship traffic.
- However, the researchers also point out that litter of Indian origin on beaches and mangroves of the Andaman Islands is continuously increasing.
- This is probably due to lack of proper guidelines and inadequate staff to monitor these islands.

RNA interference ( RNAi):
RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules. Historically, RNAi was known by other names, including co-suppression, post-transcriptional gene silencing (PTGS), and quelling.
