Indian-origin researcher develops antiviral therapy that block Covid transmission

"To our knowledge, this is the only single-dose antiviral that reduces not only symptoms and severity of Covid-19, but also shedding of the virus," said Chaturvedi, first author of the paper.

A team of US scientists, including research investigator Sonali Chaturvedi, has developed a single-dose, intranasal treatment that not only reduces symptoms of multiple Covid variants but also shedding of the virus.

In a new study published in Proceedings of the National Academy of Sciences, the team from Gladstone Institutes in San Francisco showed that this new treatment, called a therapeutic interfering particle (TIP), also decreases the amount of virus shed from infected animals and limits transmission of the virus.
