The Centers for Disease Control and Prevention announced Thursday it will extend its No Sail Order for cruise ships through Sept. 30 amid "ongoing" outbreaks on some ships.

Why it matters: The order continues the suspension of cruise ships with the capacity to carry at least 250 passengers in waters subject to U.S. jurisdiction. At the start of the COVID-19 pandemic, cruise ships were hotbeds for the virus given passengers' close proximity to each other.

What they're saying: "On cruise ships, passengers and crew share spaces that are more crowded than most urban settings," the CDC stated. "Even when only essential crew are on board, ongoing spread of COVID-19 still occurs."

Flashback: Most notably, the Diamond Princess cruise ship was docked for days as more than 600 passengers were infected and the rest were quarantined starting in January.

Major League Baseball announced in a statement Sunday that it has postponed the St. Louis Cardinals' three-game series against the Pittsburgh Pirates, set to start Monday, because of a coronavirus outbreak.

Why it matters: St. Louis has had 13 games in a row postponed after seven players and six staff members tested positive for COVID-19 last week. The MLB announced Friday another Cardinals staff member and two more players tested positive for the virus. The MLB said "in light of the most recent positive test results," the league and the Cardinals "believe it is prudent to conduct additional testing while players and staff are quarantined before the team returns to play."
