  • The Indian Council of Medical Research (ICMR)-National Institute of Virology (NIV) at Pune has developed and validated the indigenous IgG ELISA test “COVID KAVACH ELISA” for antibody detection for COVID-19.
  • Most of the diagnostic material for COVID19 is imported into India from other countries. Therefore, Indian scientists are tirelessly engaged in developing indigenous diagnostics for SARS-CoV-2.
  • While real time RT-PCR is the frontline test for clinical diagnosis of SARS-CoV-2, robust antibody tests are critical for surveillance to understand the proportion of population exposed to infection.

Significance and Advantages of IgG Elisa

  • ICMR-National Institute of Virology (NIV) scientists have Developed and Validated – completely indigenous IgG ELISA test for antibody detection for SARS-CoV-2 with high sensitivity and specificity.
  • The test will have the advantage of testing 90 samples together in a single run of 2.5 hours.
  • ELISA based testing is easily possible even at district level as the ELISA kit has inactivated virus.
  • There are also minimal bio-safety and bio-security requirements as compared to the real-time RT-PCR test.
  • The test has an advantage of having much higher sensitivity and specificity as compared to the several rapid test kits which have recently flooded the Indian market.
  • ICMR has partnered with Zydus Cadila for mass scale production of the “COVID KAVACH ELISA” test kits, and this becomes one of the most crucial examples of “Make in India” in record time.

What is IgG and How does ELISA work?

  • Immunoglobulin G (IgG) belongs to immunoglobulin family, and consists of gamma (γ) heavy chain in the constant (C) region. IgG is a widely expressed serum antibody.
  • This ELISA (enzyme-linked immunosorbent assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of a target protein in biological samples such as serum, plasma, cell culture supernatants, urine and/or cell and tissue lysates.
  • Human IgG ELISA Kit has been used to determine the total IgG antibody levels in serum samples.

INS Jalashwa, deployed for “Operation Samudra Setu”, entered Kochi harbour with a total of 698 Indian nationals stranded at Maldives.

INS Magar, the second Indian Naval ship to reach Male, Maldives for evacuation of Indian citizens.

Operation Samudra Setu

  • The Indian Navy has launched ‘Operation Samudra Setu’ as a part of national effort to repatriate Indian citizens from overseas.
  • It envisages to bring back around two thousand Indians in two ships during the first phase of evacuation.
  • INS Jalashwa and INS Magar are being operated as part of efforts to repatriate Indian nationals from foreign shores.
  • INS Jalashwa is the largest amphibious platform in the Navy. It can normally accommodate 1,000 people but will take about 800.

Vande Bharat Mission

  • Vande Bharat Mission will become the biggest evacuation exercise to bring back Indian citizens stranded abroad amidst the coronavirus-induced travel restrictions.
  • ‘Vande Bharat Mission’ will see 64 flights being operated from May 7 to May 13 to bring back around 15,000 Indian nationals stranded abroad.
  • Air India and its subsidiary Air India Express will operate 64 flights to bring back stranded Indians from 12 countries.
  • The mission has given priority to Indian citizens with “compelling reasons to return” – like those whose employment have been terminated, those whose visas have expired and not expected to be renewed under the present circumstances and those who have lost family members in recent times.

Defence Research and Development Organisation (DRDO) has developed an automated contactless UVC sanitisation cabinet, called Defence Research Ultraviolet Sanitiser (DRUVS).

It has been designed to sanitise mobile phones, iPads, laptops, currency notes, cheque leafs, challans, passbooks, paper, envelopes, etc.


DRUVS UltraViolet to Sanitise
  • The DRUVS cabinet is having contactless operation.
  • It provides 360-degree exposure of UVC to the objects placed inside the cabinet.
  • The RCI has also developed an automated UVC currency sanitising device, called NOTESCLEAN.
  • Bundles of currency notes can be sanitised using DRUVS, however disinfection of each currency notes using it will be a time consuming process.
  • It picks the notes one by one and makes them pass through a series of UVC lamps for complete disinfection.

How does UV help in Disinfection and how is it better?

How UV Works in Disinfection
  • UV light in the range of wavelengths between 200 and 300 nm is capable of inactivating microorganisms, such as bacteria and viruses, thus disinfecting both air and solid surfaces.
  • Often, chemical disinfectants are not enough to remove the bacteria and viruses found in hospitals and other contamination prone environment.
  • Rapid decontamination of the used patient-care beds and hospital rooms before admission of subsequent occupants is a major requirement in hospitals in view of the limited availability of beds.
  • Coronavirus is sensitive to UVC light, as in the case of other viruses and bacteria.
  • The germicidal effects of UVC irradiation with a peak intensity at 254 nm results in cellular damage of the virus, thereby inhibiting cellular replication.
  • Unlike chemical approaches to disinfection, UV light provides rapid, effective inactivation of microorganisms through a physical process.
