"Those are really important people because they can actually help us stop this epidemic.

The Stanford test will observe whether favipiravir will not only reduces symptoms but also shortens viral shedding, the spread of the virus to others.
Transmission among family members is a major concern.

"It's honestly a disservice when we say 99% of cases are harmless or, hey, 80% of cases are asymptomatic or mildly have nothing to worry about. There's still a large portion of people who could really benefit from an outpatient treatment," said Patel.
Other oral drugs are also being evaluated.
"One drug or another might not work, or it may not work all by itself. And so the question is, might it be possible to combine drugs?" said Dr. Maldonado.
