The locally developed Feluda, named for 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 low cost 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 in just a few minutes at a limited cost but with significantly lower accuracy.

India cinemas reopen, hoping to lure back movie-mad fans

  India cinemas reopen, hoping to lure back movie-mad fans The films may be old, masks mandatory and the usual lavish menus absent, but Indian cinema-owners hope movie-lovers will still flock back Thursday when theatres begin reopening after a nearly seven-month coronavirus shutdown. The pandemic has clobbered cinemas around the world, but in India, it has upended a culture that treats movies as something of a religion, and its stars as gods. After the recent loss of several luminaries to coronavirus, cancer and even suicide -- as well as a raging scandal over drug use in Bollywood -- the world's most prolific film industry is desperate for some good news. require(["inlineoutstreamAd", "c.

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 timeframe, 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 500 rupees ($6.80) -- around a fifth of what a PCR test costs in New Delhi.
