New intranasal anti-viral treatment may block Covid transmission

Covid news: Researchers have developed an intranasal anti-viral treatment for COVID-19 that decreases the amount of SARS-CoV-2 shed from infected animals and limits transmission of the virus. By the time people test positive for COVID-19, the SARS-CoV-2 virus has already taken up residence in their respiratory system. With each breath, people expel invisible viral particles into the air -- a process known as viral shedding.
