WASHINGTON — Planners for the Democratic National Convention are looking at “contingency options” in case the mid-July gathering in Milwaukee can’t take place because of the coronavirus, officials said on Monday for the first time.

“As we navigate the unprecedented challenge of responding to the coronavirus, we’re exploring a range of contingency options to ensure we can deliver a successful convention without unnecessary risk to public health,” said Katie Peters, a convention spokeswoman. “This is a very fluid situation — and the convention is still more than three months away. We are committed to sharing updates with the public in the coming weeks and months as our plans continue to take shape.”

One person with knowledge of the discussions said Monday that “intensive scenario-planning” was taking place among officials from the Democratic National Committee, the convention committee and the Milwaukee host committee, who were all determining what to do about the convention, which is scheduled for July 13 to July 16 at the Fiserv Forum in Milwaukee.

Among the complicating factors are the uncertain nature of the professional basketball season — the arena hosting the convention is home to the Milwaukee Bucks, a top N.B.A. team likely to play deep into the playoffs if the league’s season were to restart — and how the party’s delegates will be selected. Delegates in most states are elected to the national convention from state conventions, but many state conventions, scheduled for late spring and early summer, are also being postponed.
