Newpaper test can be a game changer in India

ITS LOWCOST AND EASE OF USE CAN HELP STEM PATHOGEN SPREAD IN POOR, REMOTE AREAS

- NEWDELHI

Afast and cheap paperbased coronaviru­s test will soon be available across India, with scientists hopeful it will help turn the tide on the pandemic in one of the world’s worst- hit nations.

India has recorded more than 7.5 million infections and the outbreak has spread from densely packed megacities like Mumbai to rural communitie­s with limited medical services.

The locally developed Feluda, named after a detective in a famous Indian novel series, resembles a home pregnancy paper- strip test and delivers results within an hour. Researcher­s are optimistic that its lowcost and ease of use can help stem the pathogen’s spread in poor and remote areas. “This test doesn’t require any sophistica­ted equipment or highly trained manpower,” said co- creator Souvik Maiti, a scientist at New Delhi’s CSIR- Institute of Genomics and Integrativ­e Biology ( IGIB).

“There are lots of remote parts of India where you do not have any sophistica­ted laboratori­es ... ( The test) will be much easier to deploy; it will have much more penetratio­n.”

India currently diagnoses Covid- 19 with either RT- PCR tests, which are highly accurate but require advanced lab machinery, or antigen tests, which can give results injust a few minutes at a limited cost but with significan­tly lower accuracy.

Feluda, like other inexpensiv­e paper- based tests being developed in other countries, claims to combine the accuracy of the PCR test with the accessibil­ity of the antigen kits.

It uses the gene- editing technique CRISPR- Cas9, which recently earned its inventors Jennifer Doudna and Emmanuelle Charpentie­r the Nobel Prize in Chemistry.

Feluda has been granted government regulatory approval and Health Minister Harsh Vardhan said last week it could be rolled out in the next few weeks by Indian conglomera­te Tata Group.

If made available within that time frame, India will be one of the first countries in the world to begin mass use of such a test.

The price has not been released, but local media said it could cost around Rs500 ($ 6.80)— around a fifth ofwhat a PCR test costs in New Delhi.
