COVID Control


  • Dexamethasone
    • Is an anti-inflammatory drug, and has gained traction for its success against corona virus
    • UK's 'RECOVERY Trial' study showed success with low doses of Dexamethasone to target lung inflammation
    • As per Clinical Management Protocol, it can be used as an alternative to methylprednisolone for managing moderate to severe cases.
    • Dexamethasone is part of the National List of Essential Medicines (NLEM)
  • Hydroxychloroquine (HCQ)
    • Anti-malarial drug, which was seen as part of preventive treatment against COVID
      • WHO in June said HCQ shows very limited success in reducing mortality rate of COVID patients. Following this, India lifted all bans on its export.
    • Cleared by Ministry of Health and Family Welfare for treatment of COVID-19 patients under emergency use
  • Methylprednisolone - anti-inflammatory drug used in COVID-19 treatment
  • Favipiravir
    • Sold under brand FabiFflu, is an anti-viral drug for COVID-19 patients from age group 18-75 with mild to moderate symptoms
    • Originally developed to treat influenza
  • Itolizumab 
    • From biocon, approved by ICMR for patients with moderate to severe acute respiratory distress
    • Normally used to cure skin ailment psoriasis
  • Remdesivir
    • Antiviral drug, cleared by Ministry of Health and Family Welfare for treatment of COVID-19 patients under emergency use for patients in moderate stage requiring oxygen support
    • As part of the agreements, the drugmakers will receive technology transfer of the manufacturing process for Remdesivir, and get to set their own prices for the generic product they produce.
    • The licenses are royalty-free until the World Health Organization (WHO) declares the end of the Public Health Emergency of International Concern regarding COVID-19 or until an alternative is approved to treat or prevent COVID-19, whichever is earlier.
  • Tocilizumab
    • Antiviral drug, cleared by Ministry of Health and Family Welfare for treatment of COVID-19 patients with moderate disease with progressively increasing oxygen requirements and in mechanically ventilated patients not improving despite use of steroids
    • Thwarts pro-inflammatory cytokines released by immune system
  • Covaxin
    • Drug Controller General of India (DCGI), Central Drugs Standard Control Organisation(CDSCO) has permitted phase-I and II of human clinical trials of ‘Covaxin’, the country’s first vaccine candidate for COVID-19, developed by Bharat Biotech in collaboration with ICMR-National Institute of Virology
    • It is an inactivated vaccine, wherein a dead virus is injected into the body to generate an antibody response
  • Sputnik V
    • The vaccine is based on an adenoviral vector which normally causes respiratory viral infections. Vectors are vehicles, which can induce a genetic material from another virus into a cell.
    • The gene from adenovirus, which causes the infection is removed, while a gene with the code of a protein from another virus spike is inserted. This inserted element is safe for the body but still helps the immune system to react and produce antibodies, which protect us from the infection.
    • Sputnik V uses two vaccines using two different vectors, the second vaccination takes place in 21 days for long lasting immunity


  • Clinical Management Protocol for COVID-19
    • By Directorate General of Health Services, Ministry of Health and Family Welfare
    • Symptoms - fever, cough, fatigue, shortness of breath, sore throat and diarrhoea. They have also complained of loss of smell (anosmia) or loss of taste (ageusia)
    • Risk factors - For ages more than 60 years, and in those with underlying non-communicable disease like diabetes, hypertension, cardiac arrest, etc.
    • Treatment
      • Mild COVID-19 cases - may be given symptomatic treatment such as antipyretic (Paracetamol) for fever and pain.
      • Moderate COVID019 cases - patients will be isolated in Dedicated Covid Health Centre (DCHC) or District hospital or Medical College hospitals.
      • Severe - Hydroxychloroquine (HCQ) may be considered for any of those having high risk features for severe disease
  • Policy Responses to COVID19: Policy tracker by International Monetary Fund, summarizes the key economic responses, governments are taking to limit the human and economic impact of the COVID-19 pandemic
  • COVID-19 Economic Stimulus Index (CESI)
    • By Columbia University and World Bank, the index standardises the economic responses taken by governments, thus allowing use to study cross-country differences in policies
    • The two main components of index are: fiscal stimulus package (as a percentage of GDP) and the interest rate cut by the monetary policy authority 


  • Pre-symptomatic spread - Pre-symptomatic spread is the transmission of the virus by people who don't look or feel sick, but will eventually get symptoms later. 
  • Asymptomatic spread  - Asymptomatic spread is the transmission of the virus by people who do not have symptoms and will never get symptoms from their infection.
  • Spike protein / S protein - A protein that protrudes from the surface of SARS-CoV-2 virus that attaches it to human enzyme ACE2 receptor, after which the virus enters the cell and makes multiple copies of itself.


  • Enzyme-Linked Immuno-Sorbent Assay antibody test (ELISA)
    • developed by National Institute of Virology in Pune along with Zydus Cadila. 
    • The blood sample is placed inside the small wells of an ELISA plate. These plates are coated with the antigen or the inactivated form of the virus. If the blood contains antibodies, it binds to the antigen and a substrate solution is added to the well. The reaction usually produces a colour change, thus detecting antibodies.
    • In India, the ELISA test for Covid-19 is only approved for serosurveys - which estimate the proportion of the population exposed to infection, and for surveys in high-risk areas and segments like containment zones
  • Rapid Antigen Detection Test (RADT)
    • Approved by ICMR. RADT checks for antigen production from a nasal swab.
      • An antigen means any toxin in the body which produces an immune response.
    • It takes about 30 minutes to give result. However rapid test has been found to have a higher chance of false negatives.
  • Real Time Reverse Transcription–Polymerase Chain Reaction (RT-PCR)
    • Real time RT–PCR is one of the most precise (and expensive) laboratory methods for detecting the COVID-19 virus.
    • Cleared by ICMR, it takes about 1 day to get result
    • Once the swab is taken, RT–PCR checks for virus's RNA
    • RT–PCR cannot be used for detecting past infections, only for active infections.
  • TrueNat
    • Commonly used for tuberculosis and HIV 
    • Cleared by ICMR, it works on same principle of RT-PCR. It involves taking nasal or oral swabs
    • The TrueNat machine is small and portable, mostly running on batteries, and provides result within 60 minutes.

A positive result from ELISA or rapid antibody test may not mean the person needs isolation or is infectious; it may simply mean the person was exposed to the virus and has developed antibodies. These two tests, being cheaper than RT-PCR, are employed in large-scale population surveys


  • Convalescent plasma therapy
    • Convalescent plasma therapy is a passive immunisation process. It is simply the transfusion of plasma containing antibodies from immune survivors of infectious diseases to the affected individuals
    • As per protocol by Ministry of Health and Family Welfare , Convalescent plasma therapy may be considered for patients with moderate illness with no improvement in condition despite the use of steroids.

United Nations

The United Nations is an international organization founded in 1945.  It is currently made up of 193 Member States. The UN also provides a forum for its members to express their views in the General Assembly, the Security Council, the Economic and Social Council, and other bodies and committees. By enabling dialogue between its members, and by hosting negotiations, the Organization has become a mechanism for governments to find areas of agreement and solve problems together.

The main organs of the UN are the General Assembly, the Security Council, the Economic and Social Council, the Trusteeship Council, the International Court of Justice, and the UN Secretariat.

United Nation's Security Council (UNSC)

The Security Council has primary responsibility, under the UN Charter, for the maintenance of international peace and security

  • UNSC held its first session in 1946, India was first elected as non-permanent member of the Council in 1950-51.
  • UNSC consists of 15 members- 5 permanent, and 10 non-permanent who serve for a term of two years. 
  • Only UNSC can issue binding resolutions on its state members as per Article 25 of UN Charter.
    • UN General Assembly resolutions are recommendatory in nature, and can issue binding resolution but only on its internal functioning.
  • Every member-country of the council, including the non-permanent members, assume the presidency of the council every month. The presidency is determined in an alphabetical order.
  • To be elected as a non-permanent member of the council, each member-country requires a two-third majority of the entire assembly. The veto does not apply to procedural style (functioning of ) of council, which needs support from 9 members
  • Permanent members have veto power but they can not prevent or end a debate through this power. Non permanent members have a sort of "collective right of veto" wherein a resolution can not pass if more than six members vote against it, as a resolution needs 9 votes for majority
  • UNSC can set up subsidiary bodies called "Committees" as needed. Currently there are four committees - Counter-Terrorism Committee, Non-Proliferation Committee, United Nations Military Staff Committee, ans Sanctions Committee

International Court of Justice

  • The International Court of Justice is the principal judicial organ of the United Nations. Its seat is at the Peace Palace in the Hague (Netherlands).
    • It is the only one of the six principal organs of the United Nations not located in New York (United States of America).
  • The Court’s role is to settle, in accordance with international law, legal disputes submitted to it by States and to give advisory opinions
  • It has no jurisdiction to try individuals accused of war crimes or crimes against humanity. As it is not a criminal court, it does not have a prosecutor able to initiate proceedings
  • Its decisions are final and binding on UN members, however there is no mechanism of enforcing them.

Vaishnavism is one of the major Hindu denominations along with Shaivism, Shaktism, and Smartism. The tradition is notable for its avatar doctrine, wherein Vishnu is revered in one of many distinct incarnations.  The tradition has traceable roots to the 1st millennium BCE, as Bhagavatism, also called Krishnaism. Later developments led by Ramananda created a Rama-oriented movement. The Vaishnava tradition has many sampradayas (denominations, sub-schools) ranging from the medieval era Dvaita school of Madhvacharya to Vishishtadvaita school of Ramanuja

Sri Vaishnava Sampradaya (Sri Vaishnavism)

Sri Vaishnava Sampradaya is a contemporary sampradaya(denomination) within the Vaishnavism tradition. It was founded by Nathamuni, and its central philosopher has been Ramanuja who developed Vishishtadvaita vedanta 

Nathamuni (823 CE–951 CE)

Nathamuni (823 CE–951 CE) was a Vaishnava theologian who collected and compiled the Divya Prabandham (a collection of tamil verses). Considered the first of Sri Vaishnava acharya, Nathamuni is also the author of 'Yoga rahasya' and 'Nyaya tattva'.

Alavandar (Yamunacharya , Periya Mudaliar)

He was a Vishistadvaita philosopher in Srirangam, Tamil Nadu in early 10the century. He was the grandson of Nathamuni, and Ramanuja was his disciple. His important works were

  • Stotraratnam - a prayer in praise of Narayana
  • Siddhitrayam - which describe the Vishistadvaita school of thought, describing a relation between the soul, god and the universe
  • Agama Pramanya - stating the authority of Pancharatra agama

Ramanuja (Ramanujacharya) 1017–1137 CE

He was a Tamil Brahmin and one of the most important exponents of Vaishnavism. He wrote Sri Bhasya and Gita Bhasya. His disciple Ramananda spread his guru’s message in the northern parts of India. He was the founder of Vishishtadvaita (Vishist Advaita) philosophy that competed with the Dvaita (theistic dualism) philosophy of Madhvacharya, and Advaita (non-dualism) philosophy of Adi Shankara, together the three most influential Vedantic philosophies of the 2nd millennium.

Vishishtadvaita (Vishist Advaita)

Vishishtadvaita (Vishist Advaita) is one of the most popular schools of the Vedanta school of Hindu philosophy. It is a non-dualistic school of Vedanta philosophy. It is non-dualism of the qualified whole, in which Brahman alone exists, but is characterized by multiplicity.  Tt has been key to the spread of the Bhakti movement in South Asia. Key texts in Vaishnavism include the Vedas, the Upanishads, the Bhagavad Gita, the Pancharatra (Agama) texts, divya prabhadam, and the Bhagavata Purana.

There are three key principles of Vishishtadvaita:

  1. Tattva: The knowledge of the 3 real entities namely, jiva (living souls; the sentient); ajiva (the nonsentient) and Ishvara (Vishnu-Narayana or Parahbrahman, Supreme-self and the cause of all manifestations and in-dwelling giver of grace based on Karma).
  2. Hita: The means of realization, as through bhakti (devotion) and prapatti (self-surrender).
  3. Purushartha: The goal to be attained, as moksha or liberation from bondage.
