The COVID-19 crisis dominates our coverage this week:

• The state of Louisiana orders schools to close and halts gatherings of more than 250 people as the number of coronavirus cases rises. We replay portions of a joint news conference by Gov. John Bel Edwards and Mayor Latoya Cantrell.

• Michael Isaac Stein has been following City Hall’s response all week and has more on the economic and labor impacts of the outbreak.

• Environmental opinion writer Bob Marshall of the Times-Picayune/New Orleans Advocate talks about another crisis we can’t forget about — that of climate disruption and our disappearing coast.
