Texas sees record number of daily coronavirus deaths, cases

The novel coronavirus pandemic has now killed more than 583,000 people worldwide.

Over 13.5 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some governments are hiding or downplaying the scope of their nations' outbreaks.

The United States has become the worst-affected country, with more than 3.4 million diagnosed cases and at least 137,358 deaths.

10:49 p.m.: 15 jockeys test positive at Del Mar, races canceled

Del Mar Thoroughbred Club in California has canceled three days of horse races after 15 jockeys tested positive for COVID-19.

The races had been set to take place July 17, 18 and 19.

"Racing will return on July 24," Joe Harper, Del Mar's CEO, said in a statement. "Canceling this weekend’s races will give us additional time to monitor the situation and give the individuals who tested positive additional time to recover."

The entire group of jockeys competing at the track was tested after two -- Flavien Prat and Victor Espinoza -- tested positive individually.

Prat won the 2019 Kentucky Derby aboard Country House after a disqualification of Maximum Security. Espinoza is a legendary jockey, winning the Triple Crown aboard American Pharaoh in 2015 and taking the Kentucky Derby three times.
