23:47 President Donald Trump said he was hopeful that the US could be seeing a ''leveling-off'' of the coronavirus crisis in some of the country's hot spots for the viral outbreak.  

"We see light at the end of the tunnel. Things are happening," the president said during his daily White House briefing on the subject. But he warned that still, the US would reach ''a horrific point'' in terms of deaths. 

Trump added that some 1.67 million Americans had been tested so far and he again pushed the notion that hydroxychloroquine would be effective against the virus.  

Despite the fact that no conclusive evidence exists to support the claim, Trump said that there were ''some very strong signs'' that the drug helped and announced that the government had purchased ''a tremendous amount'' of it.

22:37 A 4-year-old Malayan tiger at New York's Bronx Zoo has tested positive for COVID-19. It is the first recorded case of a tiger testing positive for coronavirus in the US and globally. 

The zoo has been closed to the public since March 16 and the tiger began showing respiratory illness symptoms on March 27. An asymptomatic zoo employee is believed to have infected the animal. 

Some six other cats have also fallen ill, though they have not yet been confirmed positive for COVID-19. 

"We tested the cat out of an abundance of caution" and aim to "contribute to the world's continuing understanding of this novel coronavirus," said Dr. Paul Calle, the zoo's chief veterinarian. 

The zoo said there is "no evidence that animals play a role in the transmission of COVID-19 to people other than the initial event in the Wuhan market, and no evidence that any person has been infected with COVID-19 in the US by animals, including by pet dogs or cats." 

Other cases of human-to-animal transmission of coronavius have been documented, including a pet cat in Belgium and two dogs in Hong Kong. No animal deaths from the virus have been registered so far.
