Small luxury operators have tried strict testing requirements and capacity limits, but onboard outbreaks persist

Authorities around the world halted voyages on large passenger ships in March after Covid-19 tore through scores of vessels, but cruising never really stopped.
Smaller cruise ships exempted from the suspension continued to sail selected routes. To keep the deadly virus off ships, these boutique operators experimented with a variety of new precautions.
The result: They mostly failed.
Coronavirus infections repeatedly pierced so-called safety bubbles promoted by luxury cruise lines. Since June, about 200 people have tested positive for the virus on nearly two dozen cruises, according to a Wall Street Journal tally. At least one person, a crew member, died in his cabin with the virus, according to the U.S. Centers for Disease Control and Prevention.
Transmission has not been controlled sufficiently, the CDC said in a September report that cited the viruss continued spread on smaller cruise ships as one of the agencys reasons for extending its ban on sailing for large ships.
