A new cruise ship study suggests that the number of people who are infected by the new coronavirus but have no symptoms may be much higher than believed.

More than 80% of those who tested positive for the infection had no symptoms, according to the study published online May 27 in the journal Thorax. The findings could be important as lockdown restrictions begin to be eased, and they highlight the need for accurate data on how many people worldwide have been infected.

The study focused on a ship having 128 passengers and 95 crew that left Argentina in mid-March for a planned 21-day cruise of the Antarctic. The voyage began after the World Health Organization (WHO) had declared the new coronavirus a global pandemic.

Passengers who in the previous three weeks had been in countries where coronavirus infection rates were high were not allowed to board. All passengers who were allowed to board had their temperature taken before embarkation, and the ship had numerous hand sanitizing stations, particularly in the dining room. After the first case of fever was reported on day 8 of the voyage, infection control measures were immediately implemented, including confining passengers to their cabins and the use of personal protective equipment by any crew member in contact to sick passengers.

The ship arrived in Uruguay on day 13, where eight passengers and crew eventually required medical evacuation to hospital for COVID-19-related respiratory failure. On day 20, all remaining 217 passengers and crew were swab tested for the new coronavirus, and more than half (59%) tested positive. However, 81% of those who tested positive had no symptoms.

The findings suggest that coronavirus infection rates on cruise ships are likely to be "significantly underestimated," and that passengers should be monitored after leaving the ships to reduce the risk of community spread of the virus, according to the researchers. The study authors also said that the potentially high rate of false negative results obtained by current swab tests suggests the need for secondary testing.

This is an explanation as to why the testing is being reduced drastically instead of even more capacity building of Laboratories across India. The true numbers,should really proper and intensive testing would be done,would certainly reveal true numbers enough to scare us all ! What an irony that we as a human race,inspite of so much progress,are not even possesing the willpower to help fellow unemployed helpless poor populations running into billions, and neither has the populations shown any significant monetary reserves for survival . Clearly, Strict voluntary population control is the only way ahead.... Read more
