The National Institutes of Health is launching a new initiative to research the long-term effects of COVID-19.
A study published Friday found 30% of people who have had COVID-19 still have symptoms nine months after infection.
Scientists refer to this phenomenon as a post-acute sequel of SARS-CoV2 infection, or PASC.
In December, the federal government gave the NIH $1.5 billion over four years to study the long-term consequences of COVID.
