Gilead Sciences drug may help treat coronavirus symptoms, according to WHO

Gilead Sciences (GILD) was the top performing stock in the S&P 500 and was just one of two stocks in the Nasdaq-100 that was trading higher on Monday, a day when the Dow plunged more than 1,000 points due to fears about the disease spreading to Italy, South Korea and Iran.

"There is only one drug right now that we think may have real efficacy and that's remdesivir," Bruce Aylward, an assistant director-general of the World Health Organization (WHO), said at a press conference in Beijing.

WHO officials added that clinical trials for remdesivir in humans are now taking place and results could be available within weeks. Gilead Sciences was not immediately available for comment about the WHO's claims.

But Gilead Sciences said earlier this month that it has been working with Chinese health authorities to see if remdesivir, an experimental drug that has been used to treat the Ebola virus, can combat coronavirus symptoms.
