Faegre Drinker Biddle & Reath has reopened nearly all of its offices, except for its two Washington, D.C., locations, after its personnel there were potentially exposed to Covid-19 on two separate occasions, the firm said.

Although none of the firm’s lawyers and staffers have tested positive for the coronavirus, Faegre Drinker said Wednesday that two people who visited the firm last week did. The firm closed all 22 of its offices Tuesday, including those in London, Beijing and Shanghai, after learning a guest who visited its D.C. office at 1500 K Street on March 3 was diagnosed with the coronavirus.
