Gene Editing Can Stop Covid 19 Virus Transmission

Scientists have used CRISPR gene-editing technology to successfully block the transmission of the Sars-CoV-2 virus in infected human cells. This could pave the way for Covid 19 treatment. The study was published in the journal Nature Communications.

Researchers in Australia said the tool was effective against viral transmissions in laboratory tests, adding that they were hoping to begin animal trials soon.CRISPR, which allows scientists to alter DNA sequences and modify gene function, has already shown promise in eliminating the genetic coding that drives the development of cancer among children.

The team in Tuesday’s study used an enzyme, CRISPR-Cas13b, that binds to relevant RNA sequences on the coronavirus and degrades the genome it needs to replicate inside human cells. Lead author Sharon Lewin from Australia’s Peter Doherty Institute for Infection and Immunity said the team designed the CRISPR tool to recognise Sars-CoV-2. She said that once the virus is recognised, the CRISPR enzyme is activated and chops up the virus.

Facial recognition tech linked to personal health codes has been rolled out in the Chinese city of Ruili bordering Myanmar as authorities seek to squash a Covid 19 outbreak. This is the first publicly reported instance in China of facial recognition being used to track a person’s movements and health status as they enter and exit residential areas, supermarkets, transport hubs and other public places.The technique also succeeded in stopping viral replication in samples of so-called variants of concern such as Alpha. Although there are several Covid 19 vaccines already on the market, available treatment options are still relatively scarce and only partially effective.
