The cruise industry has taken a major hit amid the ongoing novel coronavirus outbreak, or officially known as the COVID-19. Two cruise ships in particular gripped international attention, where the Diamond Princess broke out the largest concentration of the virus outside Chinese mainland and the MS Westerdam was only able to discharge people on board in Cambodia after being denied entry by a number of countries.

In comparison, another cruise ship which escaped such a fate is less well-known. The experience of Costa Serena in China's Tianjin port warrants attention as it might show a textbook handling for public health emergency.

Emergency handling in three cruise ships

Costa Serena, an Italian-operated cruise ship with 3,706 customers and 1,100 crew members on board, witnessed a race of emergency relief within 24 hours.

During the period, after the Tianjin government was notified that 15 people on Costa Serena approaching Tianjin port became feverish, the government has made in-time and effective response to deal with the emergency, eventually forbidding the outbreak of the COVID-19.

However, compared with the Costa Serena, emergency handling in the other two ships raised much concern. First, the outbreak of COVID-19 in the U.S.-operated Diamond Princess on February 1 has shown the poor management of Japan, the U.S. and the UK. As a ship headed toward Japan, it took Japanese officials more than 72 hours to impose a lockdown after they were first notified about the case connected to the ship. And for blocking the spread of the virus, it demanded the passengers stay on board for 14 days as quarantine, which can increase the infection rate of passengers.

For the U.S. and the UK, the two countries tried to shave their responsibility though they are the owners of the ship and many passengers are Americans. The U.S. only decided to take action and accepted the uninfected Americans on February 18, 17 days later than the outbreak was first known.

And for the MS Westerdam, the ship was departing from Hong Kong with 1,455 passengers on February 1 and was drifting on the ocean for two weeks owing to the fear of COVID-19 infection among passengers. It finally discharged people on board in Cambodia on February 14 after quarantine inspection ensures that there were no infected passengers.

What made the difference?

It is understandable that handling an emergency of unknown virus is extremely demanding. A couple of things are the key to make the difference.
