1. ‘Delta plus’ and an emerging public health threat


  • Concerns around the world and in India about ‘Delta plus’ variant of the SARS- CoV-2


Delta plus variant:

  • Formally known as 1 or B.1.617.2.1, the Delta plus is an emerging form of the Delta variant (B.1.617.2).
  • It has an additional mutation called K417N, which has previously been identified in the Beta variant and the Gamma variant.
    • This mutation in the virus’s spike protein facilitates entry into human host cells.
      • The spike protein, an important component of the coronavirus, stimulates the virus’s entrance into human cells and causes infection.
  • It is currently a “variant of interest”, and hasn’t been classified as a “variant of concern” yet in the World Health Organization’s list.
  • Research is on to understand its transmissibility, virulence.


High number of mutations:

  • The Delta variant has a number of mutations that have allowed it to dominate in several countries, thus posing new challenges to the management of the pandemic.

High infectiveness:

  • The K417N mutation found in the Beta variant and the Gamma variant has been characterised as being highly infectious and thus there are the concerns of a new wave associated with this variant.
    • In the light of a recent spike in positivity rate in some districts of Maharashtra and the increase in the delta plus variants recorded from these districts experts have warned that Delta plus variant might be the reason behind a third wave of the COVID-19 pandemic.

Impact of the vaccines on the new variant:

  • Given the fact that the delta plus variant has significant differences compared to the strain that has been used by pharma companies to design vaccines, there are doubts being expressed on whether the existing vaccines would be effective against the delta plus variant.
  • Studies to determine the potency of Covishield and Covaxin against the Delta variant have indicated that while antibodies continued to be produced against the variant, they were fewer antibodies produced than those produced against the strain used by companies to prepare their vaccines.

Render monoclonal antibody treatment ineffective:

  • A major concern with the AY.1 is the presence of the K417N mutation. Previous studies have associated the mutation with resistance to the newly developed monoclonal antibody treatment drug, Casirivimab and Imdevimab.
  • The mutation presumably allows the new variant to “escape” antibodies in the monoclonal antibody treatment regimes.

F. Prelims Facts

1. Ebola outbreak in Guinea is over: WHO


  • Ebola virus disease (EVD) is a rare but severe, often fatal illness in humans.
  • It affects humans and nonhuman primates, such as monkeys, gorillas and chimpanzees.
  • It is thought that fruit bats of the Pteropodidae family are natural Ebola virus hosts.
  • Ebola is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals such as fruit bats, chimpanzees, gorillas, monkeys, forest antelope or porcupines found ill or dead or in the rainforest. Ebola then spreads through human-to-human transmission humans through contact with bodily fluids such as blood.
  • The 2014–2016 outbreak in West Africa was the largest Ebola outbreak since the virus was first discovered in 1976. The outbreak started in Guinea and then moved across land borders to Sierra Leone and Liberia.

  • The average EVD case fatality rate is around 50%.
  • Vaccines to protect against Ebola have been developed and have been used to help control the spread of Ebola outbreaks.


  • The World Health Organization officially announced the end of Guinea’s second Ebola outbreak.

2. NGT closes proceedings against Mekedatu dam project

Mekedatu dam project:

  • The Mekedatu dam project is envisaged on the Cauvery river.
    • Mekedatu is a deep gorge situated at the confluence of the rivers Cauvery and its tributary Arkavathi.
  • The project aims to build a reservoir across Cauvery at Mekedatu which will help store and supply water for drinking purposes for the Bengaluru city while also proposing to develop around 400 megawatts (MW) of hydroelectric power.


  • The National Green Tribunal (NGT) has closed proceedings against the Mekedatu dam project based on allegations of violations of environmental norms in the construction of the dam.

3. HC directs NHRC to examine complaints of Bengal violence


  • The National Human Rights Commission (NHRC) of India is a statutory public body under the Protection of Human Rights Act, 1993.
  • The Protection of Human Rights Act mandates the NHRC to perform the following:
    • Proactively or reactively inquire into violations of human rights by government of India or negligence of such violation by a public servant
    • The protection of human rights and recommend measures for their effective implementation
  • The NHRC consists of the Chairman and Five members (excluding the ex-officio members)
    • The Chairpersons of National Commissions viz., National Commission for Scheduled Castes, National Commission for Scheduled Tribes, National Commission for Women, National Commission for Minorities, National Commission for Backward Classes, National Commission for Protection of Child Rights; and the Chief Commissioner for Persons with Disabilities serve as ex officio members of NHRC.
  • The Chairperson and members of the NHRC are appointed by the President of India, on the recommendation of a committee consisting of:
    • The Prime Minister (Chairperson)
    • The Home Minister
    • The Leader of the Opposition in the Lok Sabha
    • The Leader of the Opposition in the Rajya Sabha
    • The Speaker of the Lok Sabha
    • The Deputy Chairman of the Rajya Sabha


  • The Calcutta High Court has directed the Chairperson of the National Human Rights Commission (NHRC) to constitute a committee to examine complaints of post-poll violence in West Bengal.

4. Abuzz with cicadas


  • Periodical cicadas have a 13- or 17-year life cycle.
  • These cicadas spend most of their lives underground. They grow burrowed in the ground by feeding on root xylem for 13 or 17 years. During this time, they complete their developmental stages entirely underground. These developed nymphs emerge from the ground by making holes and then transform into adults, reproduce and die.
  • The climate warming seems to be having an impact on their periodic emergence from the ground. With climate warming, we are seeing more four-year early emergences in larger numbers.
  • There are three species of cicadas found in the Indian subcontinent — Chremistica mixta (found in Sri Lanka), C. seminiger (found in the Nilgiri hills) and C. ribhoi (discovered in Ri-Bhoi district of Meghalaya).


  • Cicadas have emerged across eastern parts of the United States.

1. Rajasthan women vow to nurture ‘green family’

  • As part of the ‘World Day to Combat Desertification and Drought’ celebrations, women volunteers in 33 panchayats of Rajasthan planted 5,100 saplings as part of Harit Marubhumi (green desert land) drive.
  • They also took a pledge to treat the plants as “green members” of their families and owned up the responsibility of keeping the plants safe until they grow into trees, shrubs and perennial herbs.
  • The campaign apart from being an attempt at land restoration and conservation, helps highlight the crucial interconnection between humanity and nature, which in turn helps generate environmental sensitivity and empowerment.
  • The campaign was guided by Shyam Sunder Jyani, the recipient of 2021’s Land for Life Award of the UN.
    • The award was given by the UN Convention to Combat Desertification in recognition of his contribution to promote “familial forestry”,e, relating the tree with the family.

2. ‘Digital surge not to unduly raise emissions’

  • Information technology-related electricity demand is expected to increase by almost 50% by 2030.
  • The decarbonizing of the electric system and shift towards renewable energy sources will help mitigate the increase in subsequent CO2 emissions.
