US based physician and immunoplogist, Anthony Stephen Fauci, on Tuesday dismissed the validity of hydroxychloroquine as a Covid- 19 cure.
The reaction comes after the US president, Donald Trump shared a tweet of Nigerian doctor, Stella Emmanuel, who claimed the drug was a potential cure for the virus.
Although the viral tweet has been deleted by Trump, many experts have described the claim as fraudulent.
The drug had earlier been discredited by the World Health Organisation.
In an interview on ABC News, Fauci said that clinical trials of the drug proved that it was not a cure for Covid- 19.
He further called on US residents to adhere to the wearing of masks.
The Nigerian had during a two-day “White Coat Summit” in Washington, claimed that hydroxychloroquine, zinc, and antibacterial drug, Zithromax, were effective cures for the Covid-19.
The Nigerian spoke during a news conference held by a group of American doctors under the aegis of “America’s Frontline Doctors” in front of the U.S. Supreme Court in Washington DC.
